Prosoma 500mg contains the muscle relaxant carisoprodol as its active ingredient. It's prescribed for acute aches and pains in the muscles and joints, such as those brought on by sprains or other accidental injuries. By interfering with pain and muscle-relaxation signals on their way to the brain, prosoma helps to alleviate both. You should take it exactly as prescribed by your doctor because it is meant for temporary use only. Since Prosoma might produce drowsiness, dizziness, and other side effects, care should be exercised while using heavy machinery or driving a vehicle. Before beginning treatment with any medication, it is important to discuss the potential side effects and advantages with your doctor.
