Tizanidine is a muscle relaxant medication commonly prescribed to treat muscle spasms and stiffness caused by conditions such as multiple sclerosis, spinal cord injuries, and musculoskeletal disorders. While tizanidine can be an effective treatment option, it's essential to be aware of its potential side effects, which can range from mild to severe. In this article, we'll explore the common and less common side effects of tizanidine, as well as provide guidance on how to manage them and what to do if you experience any adverse reactions.
Tizanidine works by stimulating certain receptors in the brain and spinal cord, which helps to relax muscles and reduce muscle spasms. However, this mechanism of action can also lead to a range of side effects, including drowsiness, dizziness, and dry mouth. Some people may experience more severe side effects, such as hallucinations, seizures, or allergic reactions, which require immediate medical attention.
