What Is Naproxen Used For?

Naproxen is an anti-inflammatory that helps to reduce pain and swelling. It is often used to treat arthritis and gout. You can also take Naproxen to relieve period pain.

While Naproxen usually requires a prescription, 250mg Naproxen is often sold as an over-the-counter treatment for period pain.

Our online prescribers can determine the most suitable dosage of Naproxen for you, based on your condition, symptoms, overall health and age.

To begin your order of Naproxen, simply fill out our online questionnaire for one of our online doctors to review. If your order is approved before 3pm Monday-Friday, our UK pharmacy can dispatch your item the same day via a next-day delivery.

All items dispatched by our UK based pharmacy are shipped in plain packaging via next-day delivery.

How Does Naproxen Work?

Naproxen belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). These drugs are used to reduce pain and inflammation in the body.

NSAIDS work by blocking an enzyme in your body responsible for making chemicals called prostaglandins. Prostaglandins are made in response to tissue damage and, when present, cause pain and inflammation.

By blocking a specific enzyme called cyclo-oxygenase (COX), the production of prostaglandins in the body is reduced, thus reducing pain and inflammation.

How long does Naproxen take to work?

The effects of Naproxen should be noticeable after an hour of taking it. However, it may take up to 3 consecutive days of taking Naproxen for it to reach peak effectiveness.

If you feel you need to take Naproxen for longer, or you don't notice an improvement in your symptoms, speak to one our online doctors.

How Do I Take Naproxen?

Naproxen tablets are taken twice daily with food to avoid stomach ache.

You should take Naproxen around the same time every day.

Taking Naproxen alongside breakfast and your evening meal can help you to take them consistently and reduce the risk of side effects such as stomach ache.

Naproxen tablets should be swallowed whole with a glass of water.

You should take the smallest quantity of Naproxen for the shortest amount of time. Our online doctor will prescribe the most suitable dose for you during your consultation.

Can I take Naproxen with other medicines?

You should not take naproxen with other anti-inflammatory medicines, such as Ibuprofen. 

But you can take naproxen with paracetamol or over-the-counter opioid medication, such as Tramadol, for short amounts of time.

If you are not sure what you can take Naproxen with, speak to your doctor or pharmacist.

What should I do if I forget to take Naproxen?

If you forget to take Naproxen, take it as soon as you remember. If it is nearly time for your next dose, skip the missed dose and continue taking Naproxen as you normally would.

Do not take more Naproxen to make up for the missed dose.

What should I do if I accidentally take too much Naproxen?

If you accidentally take too many Naproxen tablets, seek immediate medical attention.

Go directly to your nearest accident and emergency department. Remember to take the packaging and any remaining medicine with you, so that doctors treating you know exactly what and how much you took.

Frequently Asked Questions

Will Naproxen affect my ability to drive or operate machinery?

Naproxen may cause dizziness, drowsiness or changes in vision. If you experience any of those side effects, you should not drive or operate machinery until you feel safe to do so.

Can I drink alcohol while taking Naproxen?

You should not drink alcohol while taking Naproxen. Drinking alcohol while taking Naproxen can exacerbate irritation to the stomach and increase your risk of side effects such as heartburn and stomach bleeding.

Does Naproxen cause stomach ache?

Naproxen can cause stomach ache. If you experience any stomach pain that you believe is caused by Naproxen, speak to your doctor.

You can take Omeprazole alongside Naproxen to protect your stomach. Our doctor can issue a prescription for Omeprazole if you require it.

Why can't you lie down after taking Naproxen?

Naproxen can irritate the lining of the stomach and cause gastro-oesophageal reflux or heartburn. Therefore, it is recommended not to lie down shortly after taking the medicine.

If you experience heartburn after taking Naproxen, speak to your doctor or ask a pharmacist for advice. Our online doctor may also be able to prescribe a heartburn treatment to take alongside Naproxen to prevent this side effect.

Can I take Naproxen and Ibuprofen together?

It is not recommended to take Naproxen and Ibuprofen together. This is because NSAIDs can irritate the lining of the stomach. Taking more than one NSAID can increase your risk of gastrointestinal problems such as stomach ache, heartburn, stomach ulcers, bleeding of the stomach and, in very rare cases, perforation of the stomach.

Can I take Naproxen with Paracetamol?

Yes, you can take Naproxen with paracetamol and opioid painkillers, such as Tramadol. However, you should only take pain relief medication for a short while. If you are unsure about what you can and cannot take with Naproxen, ask your doctor or a pharmacist for advice. Information on how to safely take Naproxen can be found in the patient information leaflet enclosed with your medicine.

How long can you take Naproxen for?

How long you should take Naproxen depends on the reason you are taking it. For period pain, you may only need to take Naproxen for 1 or 2 days. People with chronic pain conditions, such as arthritis, may need to take Naproxen for longer. You should discuss your condition with your doctor - they will be able to determine how long you should take Naproxen to manage your condition.

Is Naproxen addictive?

Naproxen is not an addictive substance. However, if you find yourself using more Naproxen than prescribed to manage your condition, speak to your doctor. They may be able to prescribe an alternative pain medication that may be more suitable for you.

Will Naproxen affect my fertility?

According to the NHS, Naproxen and other NSAIDs in large quantities for extended periods may affect fertility in women. There is no substantial evidence to suggest that NSAIDs affect male fertility. If you are concerned about how a medication may affect your fertility, speak to your doctor or ask a pharmacist.

Will Naproxen affect my contraceptive?

Naproxen does not reduce the efficacy of contraceptive pills, including the combined contraceptive pill, the progestogen-only pill (mini pill) or the emergency contraceptive pill. Regardless, if you have any concerns about how Naproxen may affect your contraception, ask one of our online doctors.
