Chlorzoxazone
Summary
Chlorzoxazone is used to relieve muscle pain and discomfort, which are often caused by muscle strains, sprains, or injuries. It helps reduce muscle spasms, which are sudden, involuntary muscle contractions, allowing for easier movement and less pain.
Chlorzoxazone works as a muscle relaxant by acting on the central nervous system, which includes the brain and spinal cord, to reduce muscle spasms. It calms the muscles and reduces tension, helping you feel more comfortable and move more easily.
The usual dose for adults is 250 mg to 750 mg taken 3 to 4 times a day. The maximum recommended dose is 3 grams per day. It's important to follow your doctor's specific dosing instructions based on your condition and response to treatment.
Common side effects of Chlorzoxazone include drowsiness, which means feeling sleepy, dizziness, which is a sensation of spinning, and lightheadedness, which is feeling faint. These effects are usually mild and temporary.
Avoid alcohol while taking Chlorzoxazone, as it can increase drowsiness and the risk of liver problems. Elderly patients may need a lower dose due to increased sensitivity. Do not use if allergic to Chlorzoxazone or its ingredients. Consult your doctor if you have liver disease.
