The information provided in the summary table is for reference only. It is important to consult a qualified healthcare professional before starting any erectile dysfunction treatment, including Sildenafil.

Why choose Sildenafil?

ED can be a distressing problem, and it may have a negative impact on your self-esteem and your relationships. Sildenafil offers reliable and effective treatment. It contains the same active ingredient as Viagra (sildenafil citrate), but it is a cheaper alternative. The drug is effective within one hour, and its positive effects can last for up to six hours.

How effective is Sildenafil

The dose used in each patient's situation can ensure greater or less effectiveness depending on what someone desires to achieve from their treatment. For example, some may prefer to be able to use one tablet daily, whereas others may prefer or require a lower dose, such as those having more side effects from the treatment or an older patient or those with poor underlying health issues. Whatever your require, there are different doses of the product which can be used to benefit your personal situation.

It has been clearly shown to be effective for patients with severe ED, and as such, it also appears from studies that Sildenafil also improves the quality of the patient's relationship with their sexual partner overall.

How does Sildenafil work?

The medicine works by relaxing the muscles in the veins that carry blood to the penis by preventing the action of a certain natural chemical called phosphodiesterase type-5. By doing this, it promotes increased blood flow, making it possible to get an erection during sexual activity. Contrary to popular belief, the treatment does not cause spontaneous erections or have any effect on your sexual desire; instead, you must be sexually aroused to get an erection using Sildenafil.

It is important to be aware that PDE5 inhibitors do not treat the underlying causes of ED, which can include physical problems such as diabetes and high blood pressure and psychological issues like anxiety and depression. Because of this, it is important to seek medical advice to find out why you are experiencing ED.

What does Sildenafil contain?

The active ingredient is Sildenafil citrate in doses of 25mg, 50mg and 100mg per tablet.

The inactive ingredients are:

  • microcrystalline cellulose
  • anhydrous dibasic calcium phosphate
  • croscarmellose sodium
  • magnesium stearate
  • hypromellose
  • titanium dioxide
  • lactose monohydrate
  • triacetin

What is the difference between Sildenafil and Viagra?

In medical terms, Sildenafil and Viagra are the same things. Viagra is the brand name of Sildenafil. Sildenafil is the active ingredient in 'Viagra'. They are interchangeable and can be found in packs of 4 and 8 tablets. You can find both in strengths of 25mg, 50mg, and 100mg.

What dose should I choose?

The treatment comes in tablet form, and you should never take more than one within a 24-hour period.

There are three available dosages, 25mg, 50mg and 100mg, and whilst the higher dose can increase the effectiveness of the treatment, the lower dose can incur fewer side effects.

For further information on dosages, you can speak to your doctor or consult one of our knowledgeable healthcare professionals at Click Pharmacy.

How should I take Sildenafil?

The drug usually works best when taken an hour before sexual activity though it can be taken anywhere between 4 hours and 30 minutes before intercourse. It is most effective when consumed on an empty stomach and without alcohol, and certainly, if you do eat prior to taking it, then bear in mind that a high-fat meal will negatively affect its ability to work. Once taken, it can carry on working for between four and six hours.

Side effects

As with all medicines, there are potential side effects to consider. The most common include headaches, heartburn, flushed skin, nasal congestion, indigestion, nausea, vomiting and diarrhoea. Also, note that the treatment should never be taken with nitrates because it can cause a serious and potentially fatal drop in blood pressure.

Taking too much and overdosing can be highly dangerous and will not increase the desired effects of the treatment. But it can result in side effects such as chest pains, an irregular heart rate, nausea and priapism which is an erection which cannot subside. If left untreated, priapism can lead to permanent damage and future issues with achieving an erection. If this occurs, seek medical support right away.

For further information on these issues or if your treatment does not work satisfactorily, contact your GP or consult our specialists.

Can I drink alcohol while taking Sildenafil?

Drinking alcohol should be avoided as both alcohol and sildenafil lower blood pressure which could lead to extreme dizziness and feeling faint.

Why is Sildenafil cheaper than Viagra?

In 2013 Viagra lost its UK patent, meaning new and similar drugs were formulated. Sildenafil was one of the new drugs, so it is considerably cheaper despite it containing the same ingredients.
