What is erectile dysfunction?

Erectile dysfunction is a term that broadly covers a wide range of symptoms. It can explain the inability to obtain an erection, the inability to sustain an erection or the inability to climax. There are a number of physiological and psychological issues which can cause erectile dysfunction.

Psychological causes of erectile dysfunction include:

  • Stress
  • Anxiety
  • Depression

Physiological causes of erectile dysfunction include:

Erectile dysfunction may not affect men all the time. It is possible to experience erections in the morning soon after waking up, but not experience erections during sexual activity. If this is the case, it may be an emotional factor at play.

Speak to your doctor about the options available, including cognitive behavioural therapy (CBT), sex therapy or other psychotherapy treatments.

Sufferers of erectile dysfunction experience it differently from one another, which is why there are a variety of treatments for this condition.

What type of erectile dysfunction is Sildenafil suitable for?

Sildenafil is an erectile dysfunction medication that is suitable for those that have trouble obtaining an erection. Where Cialis and Levitra work by sustaining an erection for someone who is already aroused and sexually stimulated, Sildenafil works similarly to Viagra, in that it increases blood flow to the penis just before sex begins.

What is Sildenafil?

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor that works by relaxing the blood vessels, increasing the blood flow to the penis during sexual stimulation.

During sexual arousal, tissues within the penis release a chemical called cyclic guanosine mono-phosphate (cGMP) which causes vasodilation (dilation of the blood vessels), increasing blood flow to the corpora cavernosa - a pair of cylindrical chambers which fill with blood, producing an erection.

PDE5 inhibitors, such as Sildenafil, stop the enzyme (phosphodiesterase) from degrading the cGMP. These cause blood vessels to stay dilated, resulting in a longer lasting erection.

The medicine typically starts to work between 30 and 60 minutes after dosage, though the tablet can be taken up to 4 hours before engaging in sexual activity.

At least two-thirds of men who took Sildenafil for erectile dysfunction reported an improvement in erections. Please understand that Sildenafil is not an aphrodisiac and does not cause sexual excitement. Taking a tablet will not instantly cause an erection, but will make it easier for an erection to happen when sexually stimulated.

Does sildenafil make you last longer?

While sildenafil helps to achieve and sustain an erection in men with erectile dysfunction, it does not treat premature ejaculation.

If you are experiencing premature ejaculation, speak to your doctor.

Warning: You should never take treatments for erectile dysfunction alongside medicines for premature ejaculation.

How to take Sildenafil?

On an empty stomach, swallow one tablet with water an hour before having sex. It will take longer to work if you've eaten a heavy meal.

The effects of Sildenafil can last for up to four hours.

If you experience an erection which lasts longer than 4 hours, speak to your doctor or go straight to your nearest A&E department. Prolonged erections can cause damage to the penile tissue.

What forms of Sildenafil are available?

Sildenafil has different dosages. Our online doctor will prescribe the most suitable dosage for you, based on your medical questionnaire.

You can buy Sildenafil online from our online prescription service in blister packs containing 2, 4, 8, 12 or 24 tablets, in dosages of 25 mg, 50 mg and 100 mg.

To begin your order, simply fill out our medical questionnaire and our online prescriber will determine whether Sildenafil is suitable for you.

Staying safe with Prescription Doctor

We want you to stay safe when taking Sildenafil which is why we ask you to to provide important information during your online consultation.

Speak to your doctor before taking Sildenafil if you:

  • Have heart, blood or circulation problems
  • Have problems with your liver or kidneys
  • Are taking any other kind of medication, especially any kind of erectile dysfunction treatment or nitrates (commonly prescribed for chest pain)
  • Have any deformity of the penis, such as scarring, severe curvature or Peyronie's disease
  • If you have vision problems.
  • Have a condition which causes prolonged erections (priapism)

Sildenafil should not be used by women. Keep Sildenafil and other medicines out of reach from children.

Side effects of Sildenafil

All medications have side effects, some worse than others. Educating yourself can significantly reduce your risk of side effects as you know just what to look for. Always read the patient information leaflet and contact your GP if you have any queries about your medication.

Side effects can include:

  • Dizziness
  • Headache
  • Vision problems
  • Back or chest pain
  • Skin problems
  • Increased heartbeat (tachycardia)
  • Awareness of heartbeat (palpitations)
  • Digestion problems.

If the treatment does not work, do not take another dose. Contact a doctor or pharmacist.

If you experience an erection lasting longer than 4 hours, consult a doctor immediately. If left untreated for longer than six hours, prolonged erections can cause permanent, irreversible damage to the penile tissue.

Speak to a doctor or pharmacist if you are concerned about any of the above side effects.
