Has anyone used expired Mucinex and had it worked?

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.
