What is Sildenafil and how does it work?

Sildenafil is used to help men who have trouble achieving or maintaining their erection. Its active ingredient sildenafil belongs to a group of medications known as phosphodiesterase type 5 inhibitors (PDE5). Sildenafil helps relax the blood vessels in the penis, which, in the presence of sexual stimulation, allows blood to flow into the penis and helps with achieving or maintaining an erection.

How do I take it?

The recommended starting dose is 50mg of the treatment once a day maximum (24 hours). For the best results swallow the medication whole with water on an empty stomach one hour before sexual activity as food will slow down the absorption of Sildenafil and meaning it will take slightly longer to work. Eating an hour after taking the pill will not affect its activity.

How long does it take to work?

Sildenafil takes approximately 1 hour to work. It will not work without sexual stimulation.

How long does it last?

Sildenafil works with sexual stimulation and its effects can last about four hours. This does not mean that you will have an erection for four hours, but rather that you have the potential for an improved erection as long as the drug lasts in your body.

What is the difference between Viagra and Sildenafil?

Viagra is a brand name for sildenafil citrate, which is also sold as a generic Sildenafil at different doses. They are essentially the same treatment, with the generic medicine sold at a fraction of the cost but medically equivalent in its efficacy, quality, and strength.

Can I buy Sildenafil over the counter?

You can buy Sildenafil from some UK pharmacies after a consultation with the pharmacist. However, not all pharmacists and pharmacies offer this service.

Can I take Sildenafil with other ED medications?

You should not take Sildenafil with any other PDE5 inhibitor unless specifically instructed by your doctor. If you would like to try different ED medications, you can do as long as only 1 tablet is taken in a 24 hour period. You can see our specially priced ED Trial Packs here


FAQs (skip)

What is Sildenafil?

Sildenafil Citrate is the active ingredient found in the erectile dysfunction medication Viagra. Since Pfizer’s patent on Sildenafil expired, other manufacturers have been able to produce a generic form of the medication which is generally available at a much lower cost. Sildenafil is available in three strengths: 25mg, 50mg and 100mg.

How long does Sildenafil last?

For most men, Sildenafil (Viagra) remains effective in the body for up to four hours. Sildenafil (Viagra) will reach peak effectiveness around thirty minutes after taking the tablet and usually last for up to four hours before the effectiveness starts to diminish.

What is Sildenafil used for?

Sildenafil (Viagra) is a medication primarily used to treat erectile dysfunction. Erectile dysfunction can be caused by a problem with one of the many complex biological or psychological processes responsible for achieving and maintaining an erection. Sildenafil (Viagra) is used to treat erectile dysfunction by increasing blood flow to the penis during sexual arousal.

How does Sildenafil work?

Sildenafil (Viagra) works by inhibiting the action of a chemical called Phosphodiesterase type-5 (PDE5). When released by the body, PDE5 contributes to the loss of an erection by causing a reduction in blood flow to the penis. Sildenafil (Viagra) works by blocking the effect of PDE5 to increase blood flow, helping the patient to achieve an erection and maintain it for longer.

How long does it take for Sildenafil to take effect?

Sildenafil (Viagra) starts to work in the body after just 30 minutes. Sildenafil (Viagra) can take longer to work if the tablet has been taken with food. For Sildenafil (Viagra) to work and cause the patient to get an erection, they will need to be sexually aroused.

What is the difference between Viagra and Sildenafil?

Viagra contains the active ingredient Sildenafil Citrate. Viagra is produced by the pharmaceutical company Pfizer. The generic Sildenafil has been available for alternative manufacturers to produce since the Pfizer patent for Viagra expired. Medically, Sildenafil and Viagra are equivalent as they both contain Sildenafil Citrate, however, the excipients used to formulate the tablets may differ.

Who manufactures Sildenafil?

Originally, Sildenafil was manufactured under the brand name of Viagra by the company Pfizer. Sildenafil is now able to be manufactured by other companies as the original product patent by Pfizer has now expired. There are many manufacturers that currently produce Sildenafil to be sold in the UK market.

Will Sildenafil help with premature ejaculation?

Sildenafil (Viagra) is used to treat erectile dysfunction (ED) and will not directly help with premature ejaculation (PE). An alternative medication that has been proven to help with premature ejaculation is Dapoxetine (Priligy), which can be found here.

Can you take Sildenafil with alcohol?

Taking Sildenafil (Viagra) with alcohol is not recommended for a number of reasons. Taking Sildenafil (Viagra) with alcohol can increase your risk of experiencing side effects, it could also adversely affect your ability to achieve and maintain an erection.

Can Sildenafil be taken daily?

Sildenafil (Viagra) is not intended for use as a daily medication. Sildenafil (Viagra) has an effective time frame of four hours and should be taken as and when required, at least thirty minutes before intercourse. For a longer lasting daily effect, Tadalafil (Cialis) is available in a daily dose and is equally as effective as Sildenafil (Viagra) or Sildenafil (Viagra Connect).
