    Does penicillin expire?

    A:

    Although penicillin does not necessarily go bad, it should not be taken past its expiry date as it will lose effectiveness with time, according to Mayo Clinic. When doctors prescribe penicillin, patients need to take the full course of the antibiotics to clear up the infection completely. If a dosage is missed, the patient should take it as soon as possible but should not double the dose.
