You should avoid these medications if you have a personal or family history of substance use disorder. There are no over-the-counter (OTC) muscle relaxants in the United States.

Missed Dose

Antispasmodics have more side effects than NSAIDs and acetaminophen, so it’s important to talk to your healthcare provider about the benefits and risks of taking these medications. Although antispastics and antispasmodics are both types of skeletal muscle relaxants, they have specific and different uses. In addition, some of these medications treat conditions not related to muscle function. For example, providers sometimes prescribe diazepam to treat anxiety and seizures. Because it’s generally prescribed as a short-term response to acute pain, Flexeril abuse is rather unlikely. However, cyclobenzaprine and other muscle relaxants can be abused if they’re taken in excessive doses, so patients should be careful to adhere to their doctor’s instructions.
