WebMD reports that patients frequently use the drug in conjunction with rest and physical therapy. Patients take the drug orally up to three times a day. A time-release, once-daily version of the drug is available under the brand name Amrix, and some compounding pharmacies incorporate cyclobenzaprine into topical creams. The drug is designed for short-term use, which is usually a period of three weeks or less unless otherwise specified by a physician.
