As a rule of thumb, Viagra and other medications have a shelf life of about 2 years. Viagra's expiration date is comparable to other common ED medications, including: Stendra (avanafil) Cialis (tadalafil)

Can Viagra be used after expiration date?

Does Viagra Expire? Like most medications, Viagra can become less effective over time and expire if it's left unused for too long. Take note of the expiration date printed on your Viagra or generic sildenafil and aim to use the medication as prescribed before it expires. If your Viagra has expired, do not use it.

What happens if I take an expired Viagra pill?

Whilst the chances are that expired Viagra will do nothing for you or your erections, you don't need to worry about specific side effects associated with taking it after its expiry date. The side effects of Viagra instead remain the same: dizziness, headaches, indigestion, and, in rare cases, priapism.
