Lorazepam, a medication commonly prescribed for anxiety and insomnia, has an expiration date that indicates when the drug may begin to lose its potency or change in composition. The exact shelf life of lorazepam can vary depending on its formulation, storage conditions, and the manufacturer.
How Long Can You Keep Lorazepam?
Generally, lorazepam tablets and oral solutions are considered stable for their labeled expiration date when stored properly. This date is determined through stability testing by the manufacturer. After this date, the drug's efficacy may decrease, though it does not typically become harmful unless there are signs of degradation like changes in color or texture [1].
What Happens if You Take Expired Lorazepam?
Taking expired lorazepam is generally not advised. While it's unlikely to cause immediate harm, the medication's effectiveness may be reduced, meaning it might not work as well as intended. In some cases, degraded medication could potentially have altered chemical properties. It is always best to consult a pharmacist or healthcare provider if you have concerns about taking expired medication [1].
Where Can I Find Lorazepam Patent Expiration Dates?

When Does Generic Lorazepam Become Available?
The availability of generic lorazepam is directly tied to the expiration of patents held by the original brand-name manufacturers. Once these patents expire, other companies can seek regulatory approval to produce and market generic versions of the drug, which are typically less expensive [2].
Who Manufactures Lorazepam?
