How long does Viagra last?

14th October 2019

The time has come to try the blue miracle pill. You've heard it can help treat erectile dysfunction, and you are curious how long it should make you last in bed. There are several things to consider, such as:

  • how long Viagra remains in your system,
  • once it "kicks in", how long will your erection remain,
  • what is the "half-life" of Viagra in your body after taking it,
  • does food interact with Viagra, changing how it makes your body react to the medication?

We will discuss all of these questions below.

How long does Viagra remain in your system?

Depending on your metabolism, Viagra can take five to six hours to fully leave your system. A higher dosage will take longer to leave your body. A 25-mg dose may wear off after a few hours, but a 100-mg dose may take nearly four times as long to leave your system (up to 12 hours). Naturally, you want to take Viagra at a time when the peak dose in your system coincides with the time you anticipate having sex. Viagra typically "kicks in" within a half-hour to an hour after taking. This can change slightly based on what your last meal was. Following are food facts you should take into consideration when taking Viagra:

Foods to avoid when on Viagra

  • Don't consume Grapefruit. Grapefruit affects enzymes in your stomach in an odd way that changes the way Viagra works. You actually absorb more viagra when you consume Grapefruit, however, it takes longer for your body to process it. Remember above when we stated it takes around a half-hour to an hour for Viagra to "kick in"? A study found that Viagra absorption was 23% higher if consumed with Grapefruit, but that the desired effect was delayed. These changes in how Viagra works differed depending on the brand of grapefruit juice and the amount consumed. Because grapefruit juice effectively changes the dosage absorbed, and because the time Viagra begins to have its desired effect is altered, it is advised to not consume grapefruit juice when using Viagra.
  • Also avoid Pomegranate. Pomegranate can affect enzymes similar to grapefruit. Another study showed that the use of Viagra with pomegranate juice can lead to the development of priapism (priapism is a persistent and painful erection).
  • Don't consume a high-fat meal. If you consume Viagra after a high-fat meal, it can change the timing of Viagra's desired effect and amount absorbed. Fatty meals, such as steak or fries, can delay or prevent Viagra's absorption, giving less of the desired result and causing it to happen at an unpredictable time.

Is it ok to take Viagra on an empty stomach?

The best solution for using Viagra is to take it on an empty stomach. Because it takes effect between 30 minutes to an hour, it should not inconvenience your eating schedule too badly. Of course, you can eat after having sex!

How long does an erection last when taking Viagra?

When asking "how long does Viagra last?", perhaps you are more interested in "how long does the erection last", rather than how long does viagra remain in your system after having sex. No studies are addressing whether Viagra makes you last longer, however, it is possible to have multiple erections off one dose of Viagra. Viagra can reduce the "refractory period" (the period a man needs to recover after having an orgasm). One study showed that Viagra shortened the refractory period by an average of 11 minutes for a group of 20 men who were around 32 years old.

Will Viagra become less effective over time?

Becoming "used to" a medical treatment (where it becomes less effective over time) is called "tolerance". It is difficult to say whether Viagra makes people more "tolerant" over time. This is because the underlying condition causing the need for Viagra may have worsened and this may be the cause of Viagra no longer being as effective as it once was. While there is anecdotal examples of Viagra tolerance, there are others who report no increase in tolerance over many years. In one four-year study, men who suffered from radiation-associated erectile dysfunction reported their Viagra use. 363 men took part in the study. The following are findings of the study.

Initially 75% of the men responded to the treatment. After almost four years of follow-up, “96% of the men who initially responded to Viagra were still taking the drug, and all but six of the men said the drug was still effective,” Dr. Zelefsky said.

It is surprising that only 6% of the men no longer responded to Viagra as they once did, after four years. It is possible that the men could have reduced sensitivity to Viagra simply because they were four years older. The conclusion is that Viagra is not known to become less effective over time or cause issues of tolerance, such as you might expect from opioid-based pain medication.
