Can Cyclobenzaprine be used when it expires?

No, Cyclobenzaprine is a muscle relaxant used primarily for the short-term treatment of muscle spasms and certain other musculoskeletal pain. It is usually administered orally and commonly comes in tablet or capsule form. It usually begins to work about an hour after ingestion, relaxing muscles and relieving muscle spasms. The expiration date of the drug is estimated using stability tests based on good manufacturing practices as determined by the U.S. Food and Drug Administration (FDA). In most cases, there is no harm in taking medications that have expired. However, this is not true for many liquid-based medications. And by taking expired medications there is no guarantee that the medication will be effective, and there may be an increased risk of symptoms or unknown adverse reactions. In addition, expired medications carry the risk of bacterial growth. This can lead to infection, irritation and other potentially harmful side effects. For this reason, it is often recommended that expiration dates be adhered to in order to obtain optimal effectiveness and safety.
