When you get Viagra from the pharmacy, the pharmacist will add an expiration date to the label on the bottle.
This date is typically 1 year from the date they dispensed the medication.
The expiration date helps guarantee that the medication is effective during this time. The current stance of the Food and Drug Administration (FDA) is to avoid using expired medications. If you have unused medication that has gone past the expiration date, talk to your pharmacist about whether you might still be able to use it.
Storage
How long a medication remains good (also called shelf-life) can depend on many factors. These factors include how and where you store the medication.
Viagra tablets should be stored at room temperature between 68oF and 77°F (20oC and 25°C). It should be kept in a tightly sealed container away from light. Avoid storing this medication in areas where it could get damp or wet, such as in bathrooms.
