What are the benefits?

Sildenafil citrate tablets are available in a 25mg, 50mg or 100mg dose.

Sildenafil citrate is prescribed for the treatment of erectile dysfunction (also called impotence) in men.

How does this treatment work?

Sildenafil citrate improves blood flow by blocking the action of a chemical called phosphodiesterase type 5. This relaxes your blood vessels and boosts blood flow to the penis, which can help you maintain an erection.

It is also the ingredient found in the branded medicine Viagra, and is often called generic Viagra.

How do you use it?

You should take one sildenafil citrate tablet one hour before having sex. Please read the printed information leaflet inside the pack for full details of how to take this treatment.

Please Note: Do not take more than your prescribed dose of sildenafil citrate if you do not get an erection or if it does not last long enough. If you take more than your prescribed dose, seek medical advice immediately.

Who can use it?

Sildenafil citrate should not be used by women or anyone under the age of 18.

Also, if any of the following apply to you, sildenafil citrate may not be suitable for you, or you may have to take extra care while taking it:

  • You have a disease, injury or deformity of your penis (eg. Peyronie’s disease)
  • You have heart disease or circulation problems such as angina
  • You have low blood pressure
  • You have had a stroke or heart attack
  • You have an allergy or sensitivity to sildenafil citrate

Did you know?

Erectile dysfunction is very common, and is thought to affect around half of all men between the ages of 40 and 70.

However, many people may not realise it’s often linked with other medical conditions, including:

  • Diabetes
  • High blood pressure
  • High cholesterol

According to the Sexual Advice Association, two thirds of men with raised blood pressure are affected to some degree by erectile dysfunction. Sixty-four percent of men who have had a heart attack were also affected by erectile dysfunction for up to three years before their attack.

Other conditions that may cause erectile dysfunction include:

  • Multiple sclerosis
  • Parkinson’s disease
  • Spinal injury
  • Stroke
  • Over or underactive thyroid gland
  • Hypogonadism

Other considerations
