Sildenafil Summary

What Are Sildenafil Tablets?

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.

You can also read more about Sildenafil, other ED treatments and condition information at the NHS Choices website.

Effectiveness

The effectiveness of Sildenafil is proven in clincail trials against placebo. In men who suffered from erectile dysfunction, ~80% of those who took Sildenafil managed to achieve an erection, compared to around 17% of the group who were given water pills.

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. It is advised to try it at least 5 times before giving up. However, 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.

Cautions

Alpha-blockers and Sildenafil

If you are taking alpha-blocking medicines for high blood pressure or pulmonary arterial hypertension, such as tamsulosin or trazodone, you are advised to leave at least six hours between taking your alpha-blocker and Sildenafil.

Nitrates and Sildenafil

Sildenafil cannot be prescribed by our doctor if you are taking nicorandil or nitrate-based medication, such as GTN spray or isosorbide mononitrate tablets for angina, chest pain or heart problems. It is not recommended to take SIldenafil if you are at risk of a heart attack.

Side Effects of Sildenafil

With any medication you take, there is always a risk of side effects occurring. Some are more common than others, and often side effects may subside with the regular usage of the medicine. If the side effects do not subside, you should report them to us, or call your doctor.

• Sudden vision loss in one or both eyes. Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION).

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. If you have difficulty swallowing tablets, Nipatra (chewable sildenafil), is available.

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 benefits if successful. 

Comparisons of Sildenafil with other main ED medications are below.

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 ingredients 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.
