Does propranolol expire?

Yes. Propranolol, like other medicines, has an expiration date printed on the bottle or blister pack.

What that means:
- The manufacturer guarantees potency and safety up to that date. After it passes, potency may decline and safety cannot be guaranteed.
- Do not use propranolol after the expiration date.

Storage tips:
- Keep as directed on the label (usually at room temperature, away from moisture and heat, in the original container).

If you have expired propranolol:
- Do not take it. Dispose of it responsibly. Check local guidelines or ask a pharmacist about a drug take-back program or safe disposal.
- If you need propranolol now, contact your healthcare provider or pharmacist for a replacement prescription.

If you want, tell me the exact form (tablet, ER capsule, etc.) and the printed expiration date, and I can help you interpret it. This is general information and not a substitute for professional medical advice.
