A member asked:
Acyclovir 400 mg medicine for my cold sore expired 2 months ago? can i still use it?
A doctor has provided 1 answer
It is never a good: idea to use expired medicine, as you cannot expect the same level of potency as it should have before that expiration date. Please see your healthcare provider to see about giving you a new prescription right away. Thanks for trusting in HealthTap.
