Muscle relaxers, or muscle relaxants, are medications used to alleviate muscle spasms and pain. These drugs work by affecting the central nervous system, helping to relax muscles and reduce discomfort. They are commonly prescribed for conditions such as back pain, neck pain, and fibromyalgia. While muscle relaxers can provide significant relief, they should be used with caution due to potential side effects like drowsiness, dizziness, and dependency. Always consult your healthcare provider before starting any new medication, and ensure it fits into your overall treatment plan.
