Viagra

When Does It Start Working?

Many men wonder how long they will have to wait for the drug to work. The waiting time varies, depending on the individual. In clinical studies, Viagra began to work in as little as 14 minutes. For most men, however, it begins working within 30 minutes. The drug can continue to work for at least four hours, but, on average, the response decreases after about two hours.
 

When and How to Take Viagra

General considerations regarding when and how to take Viagra include the following:
 
  • The medication comes in tablet form. It is taken as needed, usually one hour before sexual activity. However, you should not take it more than once a day.
     
  • You should take your dose with a glass of water, although you can take it with or without food. If you take it with food, keep in mind that fatty meals may decrease the levels of Viagra in the blood.  

 

  • For the medication to work properly, you have to take it as prescribed. It will not work if you stop taking it.
     

Dosing Information

The dose of Viagra your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • Your age
  • Other medical conditions you may have
  • Other medications you may be taking.
     
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
