Sildenafil is the name given to the generic version of the blue pill used to treat erectile dysfunction. This is why Sildenafil is often known as “generic Viagra”. The branded treatment originally came onto the market in 1998, and was made exclusively by Pfizer until 2013, when the patent became available to other manufacturers. The name Sildenafil comes from the name of the main functioning ingredient in Viagra, sildenafil citrate.

  1. Rapid-response, long-lasting treatment.
  2. One tablet - no fuss.
  3. Offers a cheaper yet safe alternative to the branded version.

What is erectile dysfunction?

Although erectile dysfunction, or ED, is often referred to in medical terms as a ‘condition’, it is thought that it will affect most men at some stage during their sexually active lives. In fact, it is estimated that over 20 million men have sought treatment for the situation worldwide.

Because it is so common, and because of the more private nature of it, ED is not always an easy condition to diagnose, but most would define it as being apparent when a lack of erectile activity persistently presents a considerable obstacle to regular sexual intercourse.

What causes it?

Stress is often the cause of symptoms in those who experience ED at a younger age. This might be brought on by issues at work, or by the pressure of a sexual situation.

However, ED is much more likely to occur in men over a certain age. Lifestyle habits and lower circulation can contribute to the condition, which is thought to affect over a third of all men in the UK over the age of 60, and as many as 50 per cent of men aged 70 and over.

How is it treated?

Addressing related health issues can help, and so can treatment. Medications for ED aim to increase erectile function by improving blood flow. The presence of the condition often stems from a lack of adequate blood supply to the penis. By alleviating restrictive tension in muscles and blood vessels close to the penis, Sildenafil increases the current of blood in that area, enabling more stable and durable erections.

What is Sildenafil?

Sildenafil is named after the main component of the drug, sildenafil citrate.

Those who buy Viagra or have done so before will recognise the name sildenafil, as it is the functioning agent in this drug too.

This substance belongs to a group of medicines which are referred to as PDE5 inhibitors. Phosphodiesterase 5 (or PDE5) is a naturally-occurring enzyme in the male body, which helps to regulate blood flow. Sometimes, this enzyme can contribute to a restriction of blood flow to the penis, impairing erectile function.

PDE5 inhibitors like Sildenafil work by limiting the activity of the enzyme, and allowing muscle walls near the penis to relax and blood vessels in the area to widen. This helps to facilitate the movement of blood to the penis, and enables substantial erections.

As with most medications, you can buy Sildenafil tablets in a range of different dosage amounts, including 25, 50 and 100 milligrams. 50 mg is the typical inaugural dose for those who are trying this treatment for the first time. A doctor may see fit to increase or decrease the dosage, depending on how the user reacts to the treatment.

At present, Sildenafil is the only generic medicine for ED currently available on the UK market. You should never use treatments made by companies you don’t know and trust, and when you buy Viagra or sildenafil online, you should always use a GPhC registered pharmacy.

How is Sildenafil different to Viagra?

Viagra is the name of the original drug made by Pfizer containing the active ingredient sildenafil, and was the first prescription pill to be released on the market for the treatment of ED. Between its 1998 release and 2013, Pfizer owned the exclusive rights to produce a drug containing sildenafil for this purpose.

In 2013, this patent expired, permitting other companies to produce their own versions of the drug. These companies are however unable to call their sildenafil products Viagra, as Pfizer continued to have sole ownership of this name. The hard tablet versions produced by other companies must be simply named Sildenafil.

Sildenafil is a type of medicine called a generic. This is why it is widely referred to as generic Viagra.

There are regulations governing generics concerning their manufacture. Consequently, generic sildenafil must contain the same active ingredients in the same amounts and be manufactured under the same conditions as Viagra. So, just as you can buy Viagra in 25mg, 50mg and 100mg doses, you can also buy Sildenafil in these same dose denominations.

Interestingly, since other companies began manufacturing sildenafil for ED patients to buy in 2013, Pfizer has also entered the generic sildenafil market in addition to continuing to produce Viagra.

So even those who choose to buy Sildenafil over Viagra might in some cases still be getting a Pfizer-made treatment.

Do I need a prescription to buy Sildenafil tablets?

Yes. Because the contents of Viagra and Sildenafil are the same the UK requirements for patients to buy them from pharmacies are also the same. This means that you will need to complete a consultation with a doctor and have a prescription issued for sildenafil before a pharmacy can provide it, just as you would if you were looking to buy Viagra online or in person.

Taking it with other medicines

In the event that you are using other medication when undergoing consultation for this treatment, you should disclose the nature of these to your doctor, whether they are prescription, non-prescription or remedial. Do not cease or commence taking any other treatments without first speaking to your physician.

Medications for angina, for irregular heartbeat, nitrate-based medicines, HIV treatments, blood pressure treatments and medications for enlarged prostates may affect or inhibit your suitability to Sildenafil.

Under no circumstances should you ever use Sildenafil in addition to other treatments for impotence, or vice versa.

Q&A: our Sildenafil discussion forum

Can I still drink alcohol?

We advise against it, as alcohol may reduce the effectiveness of this medicine, and can be a contributory factor in the cause of erectile dysfunction.

Will I still be able to drive?

The treatment should not directly affect your capacity to drive. But if you experience any adverse effects which could affect your judgment or motor functions, you should avoid driving or operating heavy machinery.

How should I store it?

The tablets needs to be kept at room temperature in a dry environment. Keep them sealed in their respective blister packs until you intend to take them.

Am I allergic to anything in the medicine?

As well as the active ingredient sildenafil citrate, sildenafil tablets contain microcrystalline cellulose, calcium hydrogen phosphate (anhydrous), croscarmellose sodium, magnesium stearate, hypromellose, lactose, triacetin and titanium dioxide (E171).

If you are allergic to any of these elements, do not use this treatment.

Is it available over-the-counter?
