Cyclobenzaprine
Summary
Cyclobenzaprine is used to relieve muscle spasms, which are sudden and involuntary muscle contractions, associated with acute musculoskeletal conditions like strains or sprains. It helps relax muscles and reduce pain and discomfort, usually in combination with rest and physical therapy.
Cyclobenzaprine works by blocking nerve impulses, which are signals that cause muscles to contract, in the brain. This action helps relax muscles and reduce pain and discomfort, similar to turning down the volume on a loudspeaker to reduce noise.
The usual starting dose of Cyclobenzaprine for adults is 5 mg taken three times a day. Your doctor may adjust the dose based on your response, but the maximum recommended dose is 10 mg three times a day. It is taken orally, which means by mouth.
Common side effects of Cyclobenzaprine include drowsiness, which is feeling sleepy, dry mouth, which is a lack of saliva, and dizziness, which is feeling lightheaded. These effects are generally mild and occur in more than 10% of users.
Cyclobenzaprine can cause drowsiness, so avoid driving or operating machinery. Do not use it if allergic to its ingredients or if you have certain heart conditions like arrhythmias, which are irregular heartbeats. Avoid alcohol, as it can increase drowsiness.
