Important Facts About Sildenafil (Viagra)

Most frequent questions and answers about Sildenafil for erectile dysfunction.

Sildenafil is the active ingredient of the branded medication called Viagra. Sildenafil relaxes blood vessels in your penis, increasing blood flow when sexually stimulated.

Sildenafil (Viagra) is used for the treatment of men with erectile dysfunction (impotence).

This therefore helps when a man is unable to get or keep a hard, erect penis suitable for sexual activity. 

Sildenafil is the active ingredient of the branded medication called Viagra. The two work exactly the same but Viagra is much more expensive because of the brand name. Since Viagra has come off patent, it has become possible for other manufacturers to produce generic versions of the active ingredient sildenafil. 

An example of this can be seen with over-the-counter pain killers such as paracetamol. The brands are much more expensive but function in exactly the same way. 

Individuals react differently to medications in different ways due to various factors such as genetics and body weight. 

We recommend to start using sildenafil (or Viagra) at the 50mg dose. If this results in significant side effects like headaches, you should reduce this dose to 25mg. If you find that 50mg does not work well enough, you can try the 100mg dose. 

You can NOT take Sildenafil if you:

  • Are allergic to any of the ingredients 
  • Are taking any nitrates
  • Are taking any nitric oxide donors
  • Have a severe heart or liver problem
  • Have recently had a stroke or heart attack
  • Have low blood pressure
  • Have rare inherited eye diseases
  • Have ever lost vision to to non-arteritic anterior ischaemic optic neuropathy (NAION)

 

Sildenafil (Viagra) is the original PDE5 inhibitor, initially designed for pulmonary hypertension. It is now significantly cheaper as generic sildenafil is now available since Viagra has come off patent. 

Tadalafil (Cialis) has a much longer duration of action. 

Levitra (Vardenafil) has a slightly longer duration of action compared to Sildenafil and begins to work faster. However, no generics are available.

Spedra (Avanafil) has the fastest onset of action. No generics are available for this medication yet.

REF: The Hard Truth About Erectile Dysfunction Medication

Always take Sildenafil (Viagra) exactly as your doctor or pharmacist has prescribed. Contact your doctor or pharmacist if unsure.

Do not take Sildenafil film-coated tablets in combination with
Sildenafil orodispersible tablets.

You should take Sildenafil about one hour before you plan to have sex. Swallow the tablet whole with a glass of water.

If you feel the effect of Sildenafil is too strong or too weak, talk to your doctor or pharmacist.
