Based on U.S. Food and Drug Administration (FDA) prescribing information, about 73% of men reported an improvement in their erections after taking sildenafil.

However, as with all other medications, individual results may vary between users because everyone’s physical response to medications may be unique to themselves only.

There are many reasons why sildenafil may not be as effective for you. Some examples include, but are not limited to, the following:

  • You have not waited long enough or have waited too long to have sex after taking it.
  • The dose is not high enough (Please speak to our doctors before increasing the dose).
  • You are not sexually aroused enough (Sildenafil does not work without sexual stimulation).
  • You do not react to the medication.

Depending on your situation, our doctors may recommend trying sildenafil multiple times under different circumstances. They may also increase your dose, depending on your reaction to the medication and the influence of any side effects
