Cyclobenzaprine has been shown to reduce or abolish skeletal muscle hyperactivity. It is thought to act within the CNS at brain stem rather than spinal chord levels, although the latter may contribute to some of its therapeutic effect on skeletal muscle relaxant activity. Pharmacological studies in animals have shown a similarity between the effects of the structurally-related tricyclic antidepressants and cyclobenzaprine 10mg . The most frequently encountered adverse effects of cyclobenzaprine include the anticholinergic effects of drowsiness, dry mouth and dizziness. Other CNS effects include blurred vision, confusion, anxiety, agitation, psychosis, abnormal thinking, and hallucinations. Cardiovascular effects include increased heart rate and palpitations. The likelihood of experiencing many of these effects is dose related.
What is the most important information I should know about cyclobenzaprine?
• Do not take cyclobenzaprine if you have used an MAO inhibitor such as isocarboxazid (Marplan), tranylcypromine (Parnate), phenelzine (Nardil), or selegiline (Eldepryl, Emsam) within the past 14 days.
