Finasteride

Experiencing hair loss can be quite a stressful time for men, potentially leading to a dip in confidence. The good news is, however, that you’re not alone. Certain medications have been clinically proven to help with the problem, and you can also find support from experienced clinicians to guide you on your way.Finasteride is one such treatment. Licensed for men aged 18-41, it is only available on private prescription in the UK, so you can’t get it on the NHS. But exactly how does it help, how effective is it, and how long does Finasteride take to work?  Join us as we answer all of these questions and more, so you can make a more informed decision about whether Finasteride is right for you. Let’s get started. [medical_form product_id="168" text="START YOUR CONSULTATION TODAY" type="button"] How Does Finasteride Help With Hair Loss? Finasteride is a type 2 5α-reductase inhibitor that lowers dihydrotestosterone (DHT) levels in the scalp. DHT is the hormone that causes male pattern baldness because it reduces the size of the hair follicles until they no longer produce hair.  By blocking the conversion of testosterone to DHT, finasteride can reverse hair loss and even promote new hair growth. Research shows that after 5 years of taking finasteride 1 mg tablets daily, 48% of men rated their hair growth as improved, while 42% reported no further hair loss.  How Quickly Does Finasteride Work?Finasteride begins to lower DHT levels almost straight away, but it can take 3 to 6 months before you notice an improvement in your hair's appearance. That’s because hair follows a cycle, so it can take at least 3 months for hair to grow back and for the follicle to return to its full growth phase.    Hair growth occurs in 4 phases:Anagen: Active growth phase where cells divide quickly at the root to create new hair. This phase can last 3 to 7 years, but sometimes longer.  Catagen: A short phase that lasts 10 to 14 days during which hair stops growing, is no longer attached to the blood supply, and the follicle shrinks in size.Telogen: The resting phase, lasting about 3 months. Here, the follicle lies dormant, and 10 to 15% of hairs can be in this phase at the same time.Exogen: The shedding phase. This is where old hair falls out to make way for new, younger, healthier hair.Because it takes several months for new hair to grow from the root to a visible length, finasteride isn’t an overnight solution for hair loss. However, over time, you will notice a gradual improvement in the overall appearance of your hairline.Early Signs Finasteride is WorkingEarly signs that finasteride is working for hair loss usually appear within the first 3 to 6 months of starting treatment. The signs include reduced shedding, increased hair density, and a stabilised hairline and crown. You may notice a higher rate of hair shedding in the first few weeks of use as your hair follicles reset, but this is only temporary.How Long For Finasteride to Work: Results TimelineIf you’re considering finasteride, you're likely experiencing hair loss or are unhappy with the appearance of your hairline. Finasteride starts working immediately, but results may take some time to become apparent. It's important to understand what to expect before you start treatment so you don’t stop too soon.In this section, we’ll outline what to expect if you choose to start finasteride for hair loss.  3 Month Finasteride Results From the moment you start finasteride, it begins working, with research showing it can lower scalp DHT levels by 61.4% and serum DHT levels by 71.4%. However, in the first 3 months of treatment, you may not notice many, if any, changes; this does not mean finasteride is not working. Your hair needs to grow before the results of finasteride become obvious.It’s important that you continue finasteride treatment, even if you don't notice any results in the initial stages. Stopping treatment early means you are unlikely to see any improvements. Finasteride Results After 6 MonthsAfter 6 months, you will see better results. One study found that after 12 weeks, there was a significant improvement in male pattern hair loss, and after 48 weeks, 58% of men had improved hair growth with finasteride 1 mg tablets.    After 48 weeks, the anagen-to-telogen ratio improved by 47% in men treated with finasteride compared with placebo. This indicates that finasteride can help hair follicles transition into an active growth phase.  1 Year Finasteride ResultsAfter 1 year of consistent finasteride use, you should notice an improvement in your hair's appearance. An early study found a significant increase in hair growth on the frontal scalp after 12 months.  Everyone is different, so it may take longer for finasteride to have a noticeable effect on hair growth and thickness. However, you may notice that you are losing less hair than before. If you don’t think your hair appearance has improved after 12 months, you should speak to your clinician about alternative hair loss treatments. Long-Term Effects of FinasterideThe best results with finasteride are achieved when it is used daily for an extended period. 5-year studies have shown that finasteride is effective in up to 90% of men, with 1mg per day resulting in:48% of men have improved hair growth42% of men have no additional hair lossIn a 10-year Japanese study, finasteride improved hair loss or prevented further hair loss in 91.5% and 99.1% of men, respectively. The study also found that starting finasteride early in androgenetic alopecia (male pattern baldness) is more effective. Does Finasteride Work for Everyone?No, finasteride does not work for everyone, with clinical trials showing that it works for around 90% of men with male pattern baldness. It’s also not suitable for women with female pattern baldness, but there are treatments available for this.  Some of the common reasons finasteride does not work for all men include:Advanced stages of balding: If your hair follicles have already been destroyed, finasteride cannot restore them.Wrong type of hair loss: Finasteride is for androgenetic alopecia (male pattern baldness); it will not work for other types of hair loss.  Not using it properly: If you do not use finasteride exactly as prescribed or are inconsistent in use, it will not work effectively.  If finasteride isn’t working for you, speak to your clinician about alternative hair loss treatments.   How to Improve Finasteride ResultsIt’s easy to take finasteride: take one pill every day consistently. There are also steps you can take to support its effectiveness. From simple lifestyle changes to tracking your progress with photos, here are some ways to get the most out of finasteride for hair loss.  Take finasteride alongside minoxidil: Combining the two is more effective than using finasteride alone. Minoxidil is an over-the-counter topical solution, available under the brand name Regaine, and clinical trials show that using both improves male pattern hair loss in more than 94% of men.  Eat a healthy diet: A balanced diet rich in iron, zinc, protein, and vitamins D and B12 can help support hair health. You should be wary of excessive supplementation with vitamins A and E and minerals such as selenium, which can cause hair loss.  Be consistent: Take finasteride exactly as your clinician prescribes, as it will only be effective if used consistently.Monitor progress: Take photos of your hairline, crown, and other areas that are affected by hair loss each month. This will provide a benchmark and make it easier to track your progress with finasteride.  Avoid harsh hair care routines: Where possible, avoid harsh chemicals, excessive heat styling, and tight hairstyles that can cause damage.Remember, it can take several months to see visible results with finasteride, so it is important to continue the treatment and avoid stopping too early. If you’re concerned or don’t feel like you’re getting the results you expected, speak to your clinician for more advice.Frequently Asked QuestionsHair loss can be worrying and can cause stress and anxiety, but there are treatments like finasteride available that can improve your appearance. Before you begin treatment, it’s possible that you have questions about how it works and what results you might expect. Here, we answer some of the most common questions about finasteride.What Happens After 1 Month of Finasteride?It’s unlikely you will see any visible effects from finasteride after 1 month, but it's already working to lower scalp DHT levels. Some people notice increased hair shedding in the first few weeks to months of treatment, but this is temporary: weak hairs shed to make way for new growth. Does Everyone Shed on Finasteride?No, not everyone experiences shedding when they take finasteride, but it is a common, temporary side effect. It’s usually a sign that the medication is working and happens during the first few weeks to months of treatment as hair follicles move from a resting phase to a growth phase. This forces old, weak hair to shed, making way for new, healthier growth. Can Finasteride Grow New Hair?Yes, finasteride can help regrow new hair for many men with male pattern baldness. Studies have shown that after 1 year of finasteride treatment, 48% of men had improved hair growth, while 83% had no further hair loss, compared with 28% on placebo.  Finasteride works by blocking DHT in the scalp, which shrinks hair follicles and causes hair loss. It is more effective when started early, but results can vary, and hair loss is likely to return if treatment is stopped. {add_product_block(168)} Does Finasteride Speed Up Hair Growth?No, finasteride does not directly speed up hair growth, but it can support regrowth and increase hair density. After 2 years, finasteride improved hair growth in 66% of people, compared with 7% on placebo. It can take several months of consistent finasteride use before you notice improvements in your hair. A Consultation Service Built Around YouFinding the right support for conditions like hair loss can be challenging.

Finasteride is a popular and effective treatment for hair loss, but like all medications, it may not be suitable for everyone. There could also be life events, such as planning for a baby, that can cause you to want to stop taking it.It’s therefore essential to have a clear understanding of what to expect if you decide to come off a medication, so you can prepare yourself for potential outcomes. You should also consult a medical professional, such as a clinician, before making a final decision.So, what happens when you stop taking Finasteride? This article outlines everything you need to know.  [medical_form product_id="168" text="START YOUR CONSULTATION TODAY" type="button"] Can You Stop Taking Finasteride Suddenly?Yes, you can stop taking Finasteride suddenly. The medication is not addictive, so there’s no medical reason why you can’t cease treatment abruptly. That being said, some patients report persistent side effects after stopping Finasteride. This makes consulting a clinician beforehand crucial.Stopping Finasteride treatment can also cause hair loss to return. Indeed, most people need to take finasteride for several months or years to get the full benefit. It’s always best to discuss your reasons for wanting to cease treatment with a medical professional, as an alternative solution may be more suitable.  Reasons to Stop Taking FinasterideThere are several reasons why you might stop taking finasteride for hair loss. You might be thinking about ending your treatment if you are getting side effects that are difficult to manage, you’re not getting the results you expected, or you and your partner are considering having a baby.Some of the common reasons for stopping finasteride are:You’ve had an allergic reaction: Rarely, finasteride can cause an allergic reaction, which includes symptoms such as a rash, difficulty breathing, and facial swelling. If this happens, you’ll need to stop taking finasteride immediately and get urgent medical attention. You’re not getting the results you wanted: Although finasteride can either help regrow hair or prevent further loss in up to 90% of men, it’s not guaranteed to work for everyone. If you have been taking finasteride for 3 to 6 months and are not happy with the appearance of your hair, it may be time to discuss stopping finasteride and look at alternative hair loss treatments with your clinician.You’re thinking about starting a family: Finasteride can impact male fertility by lowering sperm counts in some people, especially if it is taken long-term. However, research shows that after stopping finasteride treatment, sperm count dramatically improved in most users.  You’re getting side effects: The most common finasteride side effects, which can affect more than 1 in 100 people, include erectile dysfunction, decreased libido, and ejaculation issues. The treatment has also been associated with depression and suicidal thoughts. If you experience finasteride side effects, let your clinician know, as they may suggest lowering your dose or switching to a topical solution, such as Regaine.    Whatever your reasons, your clinician can help you safely come off finasteride.    What Happens if I Stop Taking Finasteride?When you stop taking finasteride, you will no longer receive its benefits, so hair loss is likely to return, usually within 6 to 12 months. That’s because the effects of finasteride are not permanent, so when you stop taking it, your hormone levels will return to what they were before, leading to hair loss.You may decide to stop taking finasteride for a short period for a specific reason. For example, if you and your partner decide to have a baby, you may temporarily stop taking finasteride. Here, we discuss what could happen if you stop taking finasteride for a specific amount of time.Stopping Finasteride for a WeekIf you stop finasteride for a week, it is unlikely to have an immediate effect on your hair. Finasteride has a half-life of around 5 to 6 hours and can remain active in the body for up to 14 days, so your hormone levels are unlikely to be significantly affected if you stop finasteride treatment for a week. Stopping Finasteride for 2 WeeksThe effects of Finasteride on dihydrotestosterone (DHT) levels in the body can persist for up to 14 days after the last dose. DHT is the hormone that is closely linked to male pattern hair loss. After 2 weeks, your DHT levels will begin to rise. You’re unlikely to notice any immediate or noticeable hair loss at this time.If you continue not to take finasteride, DHT levels will return to pre-treatment levels, increasing the risk of hair loss.Stopping Finasteride for a MonthIf you stop taking finasteride for 1 month, you probably won’t notice any immediate hair loss in the first 30 days. However, your DHT levels will continue to rise because finasteride will have completely left your body. If you have stopped taking finasteride because you’re getting side effects, you should find that they will have improved or gone away in this time. Stopping Finasteride for 3 MonthsIf you stop taking finasteride for three months, you may notice that the hair growth that occurred starts to reverse, and your hair thins as it naturally would. That’s because your DHT levels have been rising and your hair follicles have begun to shrink. Stopping Finasteride for 6 MonthsAfter stopping finasteride for 6 months, hair loss is likely to return to its pre-treatment level. It can take up to one year for hair regrowth to occur or for hair retention to be lost after stopping finasteride.Some people report that they experience persistent sexual, neurological, and psychological side effects even after stopping finasteride. This is known as post-finasteride syndrome. Although more research is needed, it is important that you let your clinician know if you continue to experience side effects after stopping treatment.  How to Stop Taking Finasteride SafelyFinasteride is not addictive, so it can be stopped abruptly without gradually reducing your dose, and it will not cause withdrawal symptoms. However, it is important to discuss safely stopping finasteride with your clinician, as hair loss will return after treatment is stopped.Depending on your personal circumstances, your clinician may recommend:Stopping finasteride abruptly, also known as going cold turkeyStopping gradually by tapering your doseAn alternative topical hair loss treatment, such as minoxidilYour clinician will provide guidance on stopping finasteride based on your medical condition, personal circumstances, and future hair-loss goals. {add_product_block(168)} How Long After Stopping Finasteride Will Side Effects Stop?Finasteride side effects should go away within a few days to a few weeks after stopping the medication. It can take up to 14 days for the effects of finasteride to leave your body completely, so it may take up to a month for some sexual side effects to disappear.Although most men will not experience any long-term side effects after stopping finasteride, some report continuing to experience persistent sexual, mental (such as depression), or physical side effects. This is called post-finasteride syndrome and is an area of ongoing research, with more understanding needed to determine its causes and how to treat it.Find out more about managing finasteride side effects in our guide.Can I Start Taking Finasteride Again After Stopping?Yes, if you stop taking finasteride for a while and then decide you want to take it again, you can. You may have stopped finasteride treatment because you and your partner were trying to conceive or because you thought you had achieved the desired effect. You’ll need a hair-loss consultation with a clinician to see whether it is still suitable for you.It’s also important to note that any hair loss that occurred during the break from finasteride may not be completely regained, because earlier, continuous treatment tends to be most effective. What Happens When You Stop Taking Finasteride: Frequently Asked QuestionsStopping finasteride treatment requires careful consideration, as it may cause hair loss to return, but it may also be necessary if you are experiencing side effects or need to stop temporarily. Here, we answer some of the most common questions about stopping finasteride to help you make a more informed decision about your treatment. How Long After Stopping Finasteride Will Hair Fall Out?Hair loss will return 6 to 12 months after stopping finasteride, as DHT levels increase, causing hair follicles to shrink and shed. If you gained or maintained hair during finasteride treatment, it is likely to be lost over time. Finasteride is not a permanent cure for hair loss and needs to be used continuously and consistently for the best results.   When Does Finasteride Stop Working?Finasteride has a half-life of around 5-6 hours in men aged 18 to 60, so it can take up to 14 days for its effects on DHT levels to fully wear off. That means that after two weeks, your DHT levels will start rising.Once finasteride has left your system, it will no longer be working in the body. That means that when you stop taking it, your hair loss can return, usually within 6 to 12 months.  How to Stop Finasteride Without Losing Hair?Once you stop taking finasteride, it will no longer be working, and hair loss is likely to return. If you stop taking finasteride tablets, you may be able to switch to a topical treatment like Regaine, which contains the active ingredient minoxidil.It may also be helpful to gradually reduce your dose over several months, but you should speak to a clinician before doing this. There are also non-surgical procedures available to help manage hair loss, such as low-level laser therapy and microneedling.When Should I Stop Taking Finasteride When Trying to Conceive?Finasteride can impact male fertility by reducing sperm count. This returns to normal after treatment is stopped. If you and your partner are considering trying to conceive, you should stop taking finasteride 3 months in advance. This will give enough time for finasteride to leave your system fully and for your hormone levels to return to normal.Can I Switch to Minoxidil When I Stop Taking Finasteride?Yes, you can switch to minoxidil when you stop taking finasteride, and many men do. Minoxidil works differently from finasteride because it increases blood flow to the scalp and is available in a topical solution. After 48 weeks of treatment, topical minoxidil (Regaine) increased scalp coverage in about 60% of people.If you’re interested in trying Regaine, our clinicians can help you switch treatments. It is available as a topical foam or solution, and in 1- or 3-month supplies.  {add_product_block(321)} Support Whenever You Need UsStarting a medicated treatment programme for conditions such as hair loss is an important decision that shouldn’t be taken lightly.

If you’re experiencing male pattern baldness and hair loss, you may want to research the possibility of using medication to help with the condition. One of the options available to you is Finasteride, which is prescribed as 1mg tablets and has been shown to either help regrow hair or prevent further hair loss in around 90% of men.  While this is certainly encouraging, it’s important to note that there’s no one-size-fits-all solution, and what works for one person may not for another. This makes understanding things like side effects and how long the medication takes to work crucial.Another important piece of information is how to obtain the treatment you’re looking for, which is what we’ll cover here. So, join us as we explore where to buy Finasteride in the UK, the pros and cons of each option, and what to look for if you do decide to order online. Here we go. [medical_form product_id="168" text="START YOUR CONSULTATION TODAY" type="button"] Can You Get Finasteride on the NHS?No, finasteride 1 mg is not available on the NHS for male pattern baldness because it is considered a cosmetic treatment. You can obtain it only with a private prescription from a registered clinician at a private clinic or pharmacy. Because finasteride is only available in this form, you will need to pay the full cost of the medication.Can I Buy Finasteride Over the Counter in the UK?No, finasteride is not available over the counter in the UK because it is a prescription-only medication. You must have a prescription from a clinician to get finasteride because it is a potent treatment that can cause significant side effects, which need to be monitored.  This is especially the case with certain sexual and psychological side effects, which can persist even after treatment has stopped. Known as post-finasteride syndrome, these include conditions such as erectile dysfunction and ejaculation issues. How to Get Finasteride in the UKFinasteride can be obtained with a private prescription from a registered clinician, such as a private GP, or from an online pharmacy. You’ll need to be prepared to pay the full cost of the medication, but the prescribing clinician will provide support and advice on how best to take finasteride for hair loss. Your Local PharmacyAfter obtaining a private prescription for Finasteride, one option is to go to your local pharmacy to have it dispensed. While this sounds relatively straightforward, you may face delays if the medication is out of stock, and potentially have to deal with long queues at the desk before you can even get assistance.  Some pharmacies may be able to deliver your chosen treatment, but not all. You’d need to do your research beforehand to determine whether this is possible, which would further add to the inconvenience.    If you’re looking for a more convenient, highly confidential, and potentially cost-effective service, an online pharmacy is a better option. High street pharmacies require you to travel or queue, and if you feel anxious about discussing sensitive health issues like hair loss, a busy pharmacy may not be the most suitable option.  Private GPsIf you make an appointment with a private GP rather than an NHS one, then you may be able to be prescribed finasteride and buy it from the practice at the same time as your appointment. This may seem convenient and time-effective, but it is a costly way to obtain finasteride, and you will need to carefully consider those costs before committing to an appointment.You may need to see a private GP face-to-face to get your medication. The cost of a consultation, along with medication, can add up. This might not be the best option for you if you are worried about speaking face-to-face with someone about your condition.Online PharmaciesIf you’re wondering where to buy Finasteride in the UK, or any other treatment for that matter, online pharmacies such as Prescription Doctor are some of the most convenient, discreet, and cost-effective options. Their in-house clinicians can provide your medication after a short online consultation, usually consisting of a medical questionnaire and the uploading of photographs of the affected area. It may even be possible to receive your treatment the next day. How to Buy Finasteride OnlineYou can buy finasteride online from online pharmacies, like Prescription Doctor. The process is simple, convenient, and discreet, and you’ll usually need to complete a short online health questionnaire and, in some cases, upload photos of your hair loss for a clinician to review. Together, these will help the clinician determine if finasteride is safe for you.  Before buying any medication online, make sure you purchase from a reputable company. Here are some of the things you should look for:Check for UK registration: Make sure the pharmacy is registered with the General Pharmaceutical Council (GPhC). You should be able to find a green rectangular logo with a green cross; clicking it will take you to the pharmacy’s official entry on the GPhC register.  A physical address and contact information: Legitimate online pharmacies will have a physical street address and a phone number that you can use to contact them if you have a query. Our contact information is clearly displayed on our website.  Customer reviews: These can give you valuable insight into the pharmacy’s services, including customer care, the medications they offer, and overall service quality.Prescriptions for prescription-only medications: It is illegal for a website to sell you a prescription-only medication, like finasteride, without a valid prescription. To get one, you will need to complete an online consultation, which will be reviewed by a licensed clinician to ensure the treatment is safe and suitable for you.  If you are ever in doubt, trust your instincts. A legitimate online pharmacy will be willing to answer any questions you have before buying medications from them.  {add_product_block(168)} Here For You, For LifeAccessing the healthcare you need can be difficult. Not only do you have to deal with potentially lengthy waiting times to see a GP, but you may have to experience embarrassing face-to-face consultations.

Male pattern baldness and hair loss can be distressing and have a serious impact on confidence. While medication is available that may help, it, like all treatments, can cause adverse side effects. It’s therefore a good idea to have a clear understanding of what you could expect before you decide whether a particular treatment is suitable for you.Finasteride is one such option. Available for hair loss in 1mg tablets, it has been clinically proven to restore hair or prevent further loss in around 90% of men. The question is, what adverse effects could the treatment cause?Join us as we explore the potential impact of the medication, how long symptoms last, and how to reduce the side effects of Finasteride. We’ll also answer some frequently asked questions about the subject. Let’s get started.  [medical_form product_id="168" text="START YOUR CONSULTATION TODAY" type="button"] What are the Side Effects of Finasteride?Any medication has the potential to cause side effects, including finasteride. The most common side effects of finasteride are sex related, such as erectile dysfunction, loss of desire to have sex, and ejaculation issues. Although they are often mild and temporary, some men find they can persist, even after stopping the medication.So, it is important to understand what adverse reactions you may encounter and how they could affect you. Here, we explore the common, uncommon, and rare side effects of finasteride.  Common Side Effects of FinasterideThe most common side effects of finasteride for hair loss are related to sexual function. They are usually temporary, but they can affect your confidence if they continue. Speaking to your clinician as early as possible if you experience any of these adverse effects will help.Common finasteride 1mg side effects areErectile dysfunctionLow sex driveProducing less semenUncommon Finasteride Side EffectsUncommon finasteride side effects often affect up to 1 in 100 people who take it. Although they can be uncomfortable, they are often mild and manageable.

Potential rare side effects of finasteride are:Pain in the testiclesSigns of male breast cancerAllergic reactions (dizziness, swollen lips and tongue, itchy skin, breathing problems)  Likelihood of Experiencing the Side Effects of FinasterideSide effects are more common with the 5 mg finasteride dose than with the dose used for hair loss. One study found that adverse effects were minimal among people taking finasteride for hair loss. That said, side effects are possible, and some may persist even after treatment has stopped. It’s therefore important to have a clear understanding of what to expect before starting treatment. What are the Serious Side Effects of Finasteride?Serious finasteride side effects are rare and can range in severity. Some people may notice serious side effects after they have been taking finasteride for a few months. It is important to monitor how your body responds to finasteride so you can spot any changes as early as possible.You should see a doctor straight away if you are taking finasteride and you get:Signs of breast cancer: any lumps or swelling in your chest or nipple dischargeDepression: signs include a persistent low mood, sadness, loss of interest in activities you usually enjoy, changes in sleep or appetiteIf you get any of the following serious side effects, call 999 or get someone to take you to A&E:Thoughts of harming yourselfSuicidal ideations Serious allergic reactionSigns of a serious reaction include:Swelling of your lips, tongue, mouth, or throatDifficulty breathing or swallowingYour skin, lips, or tongue turn blue, grey, or paleYou’re confused, drowsy, or dizzyYou collapseIf you experience any side effects of Finasteride, serious or otherwise, you can report them via the Medicines and Healthcare products Regulatory Agency (MHRA) Yellow Card Scheme. Finasteride Long-Term Side EffectsLong-term finasteride use is generally safe, but it can cause persistent side effects in a small number of people. These include persistent sexual dysfunction, depression, anxiety, and, in rare cases, breast cancer. If these side effects persist after you stop taking finasteride for hair loss, it is called post-finasteride syndrome.Finasteride and Suicidal Ideations One of the most serious potential side effects of Finasteride is suicidal thoughts. In 2024, the MHRA said it had received 281 reports of depressed mood disorders and suicidal and self-injurious behaviours while taking the treatment since February 1993. If you experience any of these symptoms, it’s essential to seek emergency medical attention.Because of these risks, you will be asked some questions regarding your psychiatric history before being prescribed Finasteride. This is to help determine whether the medication will be safe and suitable for your circumstances. Are Finasteride Side Effects Permanent?Most finasteride side effects are not permanent and usually resolve on their own as your body adjusts to the medication. For some people, side effects, like erectile dysfunction, ejaculation issues, and having a low libido, can continue after they stop treatment.Finasteride clears the bloodstream relatively quickly, with a half-life (the time it takes for half the medication to be eliminated from the body) of between 5 and 6 hours in men aged 18-60. However, it may take up to 14 days for the medication's hormonal effects to wear off and DHT levels to return to normal. Most side effects should resolve or improve during this time period.If you get any finasteride side effects that continue after you have stopped treatment or do not seem to be getting better, contact your clinician for further advice.  {add_product_block(168)} How to Reduce Finasteride 1mg Side EffectsFinasteride 1mg side effects can be a bothersome consequence of taking hair loss medication. However, there are steps you can take to reduce your risk of experiencing them and to support the medication’s effectiveness. From only taking the prescribed dose to following proper storage guidelines, we discuss what you can do to lower your risk.1. Take Only the Prescribed DoseFinasteride for hair loss is prescribed at 1 mg per day; higher doses do not provide greater benefit. In fact, higher doses increase the chance of side effects. You should also aim to take the tablet at the same time every day. This will help to keep finasteride at consistent levels in your body.2. Store Finasteride ProperlyThe best way to store finasteride is at room temperature in its original packaging. This will help to keep it protected from direct light and ensure the medication remains effective. You should avoid storing finasteride in the bathroom or anywhere else where it may be exposed to excessive heat or moisture.3. Reduce Oestrogen LevelsOne reason some side effects of finasteride occur is the increase in oestrogen in the body.This accounts for erectile issues and breast tenderness or pain, for example. When DHT is eliminated, the body's oestrogen becomes stronger. Therefore, reducing oestrogen levels can help reduce side effects. Examples of how to do this include:Losing weightTaking zinc supplementsEating more cruciferous vegetables (such as broccoli, kale, Brussels sprouts, and cauliflower)You should speak to your clinician before starting any new supplements or medications while taking finasteride.4.  Take Regular ExerciseExercise is important, regardless of your activity level or the medications you may be taking for any condition. However, when it comes to reducing the side effects of finasteride, exercise can be extremely helpful.Staying active is a good stress reliever, reducing cortisol (the ‘stress hormone’) and increasing serotonin (the ‘feel good’ hormone). This can have a positive impact on any sexual issues you might be experiencing due to taking finasteride. For example, getting 160 minutes of weekly exercise for 6 months can reduce erectile problems in men. It will also help you lose weight, which, as mentioned above, is another effective way to reduce side effects.  5. Increase Vitamin DMany of us are deficient in vitamin D, so taking supplements to boost our levels is a good idea. There is some research suggesting a link between vitamin D deficiency and androgenetic alopecia.A vitamin D deficiency can affect sperm quality, and since this condition can be exacerbated by finasteride, vitamin D supplementation may help improve fertility. You can easily increase your vitamin D levels by spending time in the sun regularly. When exposed to sunlight, our bodies' cells produce vitamin D, which offers numerous benefits.6. Stop Taking the TreatmentThe easiest way to reduce (in this case, eliminate) the side effects of finasteride is to stop taking the drug altogether. Unlike some medications, finasteride is not addictive, and it will not harm you or make you unwell if you stop taking the pills each day. However, do bear in mind that if you do stop taking finasteride, your hair loss will begin again exactly as it did before – the effects of the drug only last while it is in your body.You will need to weigh up the pros and cons of what will happen if you stop taking the drug compared to the side effects you were experiencing when you did take it. The choice is ultimately yours, but it is wise to seek medical advice, especially if the side effects are more serious.Frequently Asked QuestionsAny medication can cause adverse events, but understanding what they are and how they may affect you is important. Here, we answer some of the most common questions about finasteride side effects. Do Finasteride Side Effects Go Away on Their Own?Yes, many finasteride side effects are mild and temporary and will go away on their own once your body adjusts to the medication. However, in a small number of people, finasteride side effects can persist, even after they have stopped treatment. You should let your clinician know if you experience any side effects from finasteride.Do Any Finasteride Side Effects Involve Memory?Although not listed as a side effect in the patient information leaflet, emerging research suggests there may be a link between finasteride use and cognitive dysfunction. This included activities involving memory. However, leading a healthy lifestyle, such as eating a balanced diet, getting regular exercise, managing stress, and prioritising sleep, can all help reduce the risk of memory issues.If you have any concerns about finasteride and memory, speak to your clinician for further advice.Are Finasteride Side Effects Overblown?Finasteride side effects are generally considered rare, but some people do get them. For most people, side effects like erectile dysfunction go away on their own once the medication is stopped. It is important to note that millions of people have taken finasteride and had no, minimal, or reversible side effects. {add_product_block(168)}  When Do Finasteride Side Effects Start?Finasteride side effects usually start within the first few weeks to a few months after starting treatment. Although side effects are rare, some people may get them earlier than this, while others may get them much later. You should monitor your body for any changes and discuss any side effects you get with your clinician.Are Finasteride Side Effects Reversible?Yes, most finasteride side effects are reversible and will improve after you stop taking the medication. However, in some cases, sexual side effects can last for months or years after stopping finasteride. If you are concerned about any side effects and you have stopped finasteride, contact your clinician for more advice. Reliable Support Whenever You Need ItIf you’re looking for assistance with medical conditions such as hair loss, smoking, obesity, or erectile dysfunction, you’ll want to be reassured that your situation will be handled with the utmost care, discretion, and efficiency.
