Understanding Expiration Dates: Does Viagra Go Out Of Date?

Viagra, like all medications, has an expiration date. It's important you pay attention to it to ensure your medication remains safe to use and effective at improving your sexual confidence. Our MedExpress experts break down Viagra's shelf life, how to store it and how to dispose of your expired medication, to help you stay safe while taking your treatment.

About Viagra

Viagra is one of the most well-known treatments for erectile dysfunction. It's a prescription medication that contains the active ingredient sildenafil, which belongs to a group of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Viagra is available as a brand-name medication, or you can take generic sildenafil, which is medically equivalent but available at a lower price.

It affects the smooth muscles around your blood vessels, allowing them to relax and improve blood flow to your penis when you experience sexual stimulation. [1] This helps you get and maintain erections strong enough for sex. Clinical studies show that around 80% of men report improved erections after taking sildenafil. [2]

What is Viagra's shelf life?

Generally, Viagra has a shelf life of 2-3 years. Your Viagra tablets should have their expiration date printed on the original packaging, make sure you keep this for your reference.

Drug expiration dates are worked out through a process called stability testing. Pharmaceutical companies expose drugs to lots of different factors including temperature, light and humidity to see how they affect the quality of the medicine. This gives manufacturers an idea of how a drug might break down with time. The actual shelf life is never fully tested, so it could be longer than the expiry date. That said, you should never take medication past its expiration date to avoid possible adverse effects.

How to properly store Viagra 

To ensure Viagra remains safe for use, you should store it in the packaging it came in. Keep your Viagra tablets at room temperature, away from direct sunlight and excess moisture (so don’t keep it in the bathroom).

What happens if you use expired Viagra?

If the expiration date on your Viagra has passed, we advise you don’t use it. The drug may have started breaking down, which could reduce its strength. This means it might be less effective or work for a shorter period of time compared to unexpired medication. Taking an expired medication could also cause adverse effects.

Remember: You should regularly clear out your medicine cabinet and safely dispose of expired medications.

How to dispose of expired medications

If you have expired Viagra tablets, or any other prescription drugs, you should first look at the medicine label to see if it lists any specific disposal instructions. All pharmacies can accept unwanted or expired medications and dispose of them safely. Don’t put unwanted tablets in the bin, and never flush your medications down the toilet, this can be harmful to the environment. [3]

If you have any questions about disposing of expired medications, contact your clinical team or doctor for advice.
