Vilitra (which contains vardenafil, like Levitra). The expiration date indicates the point at which the manufacturer can guarantee the drug's safety, effectiveness, and full potency. After that date, the effectiveness of the drug can be reduced, and there might be changes in how it works.

Why it matters: Reduced effectiveness: Over time, the active ingredients in medications like Vilitra can break down, meaning the pill might not work as well or as quickly.  Vilitra concerns: While most medications don’t become harmful after they expire, there's a chance that they could cause side effects or interact unpredictably with other medications.

Degradation of active ingredients: For something like Vilitra, which is meant to treat erectile dysfunction, the reduction in potency could result in insufficient effects, meaning you might not get the desired result. If you've found expired Vilitra in your medicine cabinet, it’s best to dispose of it properly and get a fresh prescription. It's always safer to use medications within their expiration period.
