Cephalon | Amrix (Medication)
Amrix is indicated as an adjunct to rest and physical therapy for relief of muscle spasm associated with acute, painful musculoskeletal conditions. Improvement is manifested by relief of muscle spasm and its associated signs and symptoms, namely, pain, tenderness, and limitation of motion.
Amrix has not been found effective in the treatment of spasticity associated with cerebral or spinal cord disease or in children with cerebral palsy. ...
Common side effects of Amrix include drowsiness, dry mouth, fatigue, headaches, and dizziness. Other reported side effects include nausea, constipation, blurred vision, unpleasant taste, nervousness, confusion, acid reflux, and abdominal pain or discomfort. Abrupt cessation after prolonged therapy may cause withdrawal symptoms such as headaches, nausea, and weakness. ...
Because of its atropine-like action, Amrix/cyclobenzaprine should be used with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic medication.
Do not take Amrix if you have used an MAO inhibitor within the past 14 days. Serious, life-threatening side effects can occur if you take cyclobenzaprine before the MAO inhibitor has cleared from your body.
You should not take Amrix if you have recently had a heart attack, or if you have a heart rhythm disorder, congestive heart failure, heart block, or an overactive thyroid.
Amrix can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert. Avoid drinking alcohol, which can increase some of the side effects of Amrix.
During pregnancy and breast-feeding it is recommended to consult your doctor before taking this medicine. ...
