Back Pain Home > Amrix
Amrix is a prescription medication used for treating muscle spasms due to injury or other muscle problems. It comes in an extended-release capsule that prolongs the effects of the muscle relaxant. Amrix works only to relieve muscle spasms caused by problems in the muscle (not by the brain or spinal cord). While most people tolerate it well, potential side effects include fatigue, constipation, and dizziness.
- Amrix comes in capsule form. It is usually taken by mouth once a day.
- You can take the medication any time of the day, but it is best to take it consistently at the same time each day. Taking Amrix in the evening may help reduce daytime drowsiness.
- In general, Amrix should only be used for two to three weeks at a time.
- You can take the medication with food or on an empty stomach. If it bothers your stomach, try taking it with food.
- Be sure to swallow the capsules whole. Do not open, crush, or chew the capsules.
- For the medication to work properly, it must be taken as prescribed. It will not work if you stop taking it.
