Does naproxen expire?

Yes. Naproxen medications have an expiration date printed on the bottle. That date is the point up to which the manufacturer guarantees full potency and safety. After that date, potency isn’t guaranteed and you shouldn’t rely on it.

Quick tips:
- Storage: Keep at room temperature, in the original bottle, away from moisture and heat; keep the cap tightly closed and out of reach of children.
- Disposal: Do not flush. Use a local medication take-back program if available. If none, you can mix pills with unpalatable material (like used coffee grounds or cat litter), seal in a bag, and discard in the trash.
- If it’s expired: Replace it with a new bottle. If you have questions about whether you should still use it, ask a pharmacist.

If you have the exact expiry date or any medical conditions (ulcers, kidney disease, pregnancy), I can tailor the advice.
