What Is Sildenafil?

Sildenafil is a drug used for erectile dysfunction in men. It is the generic form of the well-known drug, Viagra. The patent for Viagra expired in 2013, which allowed manufacturers other than Pfizer to make the medication. This, in turn, drove down the price of the active ingredient, Sildenafil. Sildenafil is a popular choice of treatment for erectile dysfunction, as medically there is no difference between Sildenafil and its branded alternative, yet Sildenafil is a much more affordable option.

How it works

Sildenafil is from a class of drug called PDE inhibitors. Men who suffer from ED are unable to pump enough blood into the penis to achieve a hard enough erection. Sildenafil helps men achieve a harder and longer-lasting erection, by stimulating blood flow to the penis, resulting in longer and harder erections for men who struggle. 

How to take Sildenafil

The typical starting dose for Sildenafil is ONE 50mg tablet 30 minutes before sexual activity. Most men will find this dose effective, however, if 50mg is too strong, you may wish to half the tablet the next time you are taking the medication. If successful, a 25mg tablet may be more suitable for your next prescription. 

If the 50mg does not achieve the desired result, you should try the same dose 2-3 more times, to see if you can achieve a satisfactory erection. If this is not successful, you can increase your dosage to 100mg. If a 100mg dose is also ineffective, speak to us about the next steps. Sildenafil should not be taken more than once in 24 hours.

If you have already used a few erectile pills without success, a face to face referral may be required. 

If you have not yet tried one of the other ED medications, you may find that Tadalafil or Vardenafil is effective for you.

Patients will find different drugs more effective. This does not necessarily mean one drug is more effective than another. It can be that your body responds slightly differently to a particular medication.

Sildenafil Alternatives

Although Sildenafil provides the most affordable treatment, it may not always be best suited to your needs. Levitra (or Vardenafil) is the most suitable treatment for people who suffer from diabetes, while Cialis (or Tadalafil), provides a longer-lasting effect. There is also now an over the counter option of Sildenafil in the form of Viagra Connect. This contains Sildenafil 50mg. 

Vitaros cream is another alternative to oral medications in treating erectile dysfunction. 

You can also look at counselling since some men suffer from erectile dysfunction as a result of nerves. If you think your ED is psychological, therapy may provide long term benefit if successful. 

Different Manufacturers

As Sildenafil is a generic medication, there are multiple manufacturers of the same drug. This means you may see differences in packaging and even the colour of the tablet from prescription to prescription. All manufacturers must meet MHRA standards, and so you can be confident the medication you receive contains exactly the same amount of active ingredient as any other.

In rare instances, some patients may notice one manufacturer is more suitable for them. This can be due to other ingredients in the medication such as colouring, which they may be allergic to. If you have noticed a particular manufacturer is better for you, please e-mail us after placing your order requesting which manufacturer you would like. We will then do our best to accommodate your request, or offer a refund if this is not possible.

Manufacturers of Sildenafil tablets in the UK include Teva, Mylan, Accord, Actavis, Dr Reddys, Sandoz and Zentiva amongst others. 

Teva Sildenafil

Many men request Sildenafil by Teva from our pharmacy. It's difficult to obtain scientific data to demonstrate that Teva Sildenafil is any more effective than any other manufacturer. Often, trends towards a particular manufacturer of a drug can be driven by online discussion forums and boards. All medication sourced by our pharmacy is from MHRA regulated wholesalers and manufacturers. There should be no medical difference between manufacturers in terms of effectiveness.
