Generally it is not recommended that drugs are used past their expiry date. This is because the manufacturer can no longer guarantee their safety or efficacy. In this case Promethazine starts destabilising once the bottle is open and exposed to oxygen making it less effective. If you were to use the expired medicine it will probably be ineffective.

I have a box of PepcidAC that is 8months past the expiration date. It is still sealed, and I wanted to know if it will still be effective?
Are they safe to take after expiration date?
