Phentermine expiration?

Phentermine expiration works like other meds. The manufacturer guarantees potency and safety only up to the date printed on the bottle or blister pack (the EXP date). Do not use phentermine after that date.

Helpful tips:
- Where to look: On the bottle cap label or the blister/box it came in. It will say EXP or Exp followed by a month/year (e.g., Exp 08/2026).
- Storage: Keep in the original container, tightly closed, at room temperature (about 68–77°F / 20–25°C), away from light and moisture. Check your packaging for any specific storage notes.
- If it’s expired: Do not take it. Ask your pharmacist or prescriber how to dispose of expired medication. Safe options include drug take-back programs or, if none are available, disposal with other household trash after following local guidance (do not flush).
- Potency: Expired meds may have reduced potency; they’re not guaranteed to work as intended and could be less effective for weight loss or symptom control.
- If you’re unsure: Contact your pharmacy for the exact expiry date of your lot, or ask your clinician about renewing.
