Does lorazepam expire?

Yes, lorazepam (like all prescription and over‑the‑counter medicines) does have an expiration date. The expiration date is the date the manufacturer guarantees the drug will remain safe, effective, and stable when stored under the specified conditions.

Typical shelf life

• Lorazepam tablets: most manufacturers label a shelf life of 2–3 years from the date of manufacture, but the exact date can vary by brand and lot.
• Lorazepam injections: similar shelf‑life periods apply, and the vial should not be used after the stamped expiration date.

Why the date matters

• Potency loss: Over time, the active ingredient can break down, making the medication less effective.
• Stability: Physical changes (e.g., tablets cracking, solutions clouding) may indicate the drug is no longer safe to use.
• Legal and safety: Using expired medication can be risky, especially for drugs that control anxiety or seizures where precise dosing is crucial.

What to do if you have an expired bottle

1. Check the label: If the bottle shows an expiration date that has passed, it’s safest not to use it.
2. Ask a pharmacist: They can advise whether the specific batch is still usable or if you should replace it.
3. Dispose properly: If you decide the medication is no longer safe, most pharmacies accept expired meds for safe disposal. Do not flush unless the pharmacist instructs you to.
4. Get a new prescription: If you need to keep taking lorazepam, schedule an appointment or call your prescriber for a refill.

Storage tips to maximize shelf life

• Keep it sealed: Store in the original container, tightly closed.
• Avoid extremes: Keep at room temperature (usually 20–25 °C/68–77 °F). Do not expose to heat, moisture, or direct sunlight.
• Avoid the bathroom: Humidity can accelerate degradation.
• Check the label: Some medications have “Use by” dates that are stricter than the generic expiration date, especially for injectable forms.

Bottom line: Lorazepam does expire. Use the drug only up to the date printed on the packaging, store it correctly, and replace any expired supply with a new prescription. If you’re unsure whether an expired vial is safe, consult your pharmacist or prescriber.
