Has anyone used expired Mucinex and had it worked?

Medically reviewed by Last updated on Nov 27, 2023.

I have Mucinex that is exactly one year expired. I know that the general rule is don’t take expired medicine, it might not work or even harm. I also know that with expiration dates they ere on the side of caution, and sometimes medicines are still effective past the date. Anyone know? Thanks.

Throw it out! The expiration date is the final day that the manufacturer guarantees the full potency and safety of a medication.
