Can your body build a tolerance to Viagra?

18th January 2021

Can you build a tolerance to Viagra? Will Viagra become less effective over time if you take it regularly? Below we discuss several studies which evaluate the effectiveness of Viagra over time, and whether you can build tolerance to it. In short, Viagra continues to work as intended for men who use it over long periods of time.

Not all men respond well to Viagra, in fact only 70% do. Some conditions of ED are not helped by taking Viagra. When a man experiences erectile dysfunction, typically it begins gradually and gets worse over time. Therefore, if Viagra loses efficiency over time, it can be difficult to tell if the Viagra is no longer doing the job, or if the ED condition has become worse so that the same dose of Viagra that used to work, no longer works.

Long Term Efficacy and Safety of Viagra

Viagra cannot cure ED, it only treats the condition. Therefore, most men who find that Viagra treats their ED will want to use it over an extended period of time. This presents two questions:

  • Is Viagra safe to use over an extended period of time?
  • Does a man build tolerance, making Viagra less effective of a treatment?

Is Viagra Safe for Long Term Use?

Viagra has now been with us for a quarter of a century. It has been found safe for use and is well tolerated both short term and long term.

oral sildenafil is effective and well-tolerated both at the initiation of therapy and during long-term treatment

Do Men Build Tolerance to Viagra?

Tolerance can be defined as medicine which becomes less effective over time because the body becomes more resistant to the benefits the medicine offers. An example of this is most prescription-strength sleeping medication, which are only recommended for two to four weeks. After using sleeping meds this long, the body no longer responds as well and users may find the pills actually begin to prevent sleep.

Does this happen with Viagra? One study was taken of a group of men. Originally, 74% of the group noticed improvements in their erectile dysfunction while taking Viagra.

After three years of use, investigators followed up with 82 of the menu. 43 were still using Viagra. Sixteen of the 43 men said they needed to increase the dose by 50mg to continue achieving an adequate erection.

While this may indicate tolerance from using Viagra for an extended period of time, it is also possible that the ED condition worsened in these men. In any event, the men were still able to enjoy using Viagra with an increased dose.

These are considered dangerous and could result in long term damage to the penis.
