Muscles tend to seize up after an injury (called a muscle spasm). Spasms can get painful and can easily limit your activities. Sometimes skeletal muscle relaxants are prescribed in conjunction with physical therapy and rest to ease tension and help you make progress with exercises. Research comparing the different types of muscle relaxers shows that for the most part, they all work equally. So deciding on which one is about anticipating side effects and drug interactions and considering your preferences. All skeletal muscle relaxers cause drowsiness and dizziness, so don't drive when you take them.

Muscular relaxants are necessary for simplification of laryngeal catheterization and maintenance of myoplegia during operative interventions. Muscular relaxants will voluntarily paralyse and weaken muscles, but do not influence negatively the brain or blood circulation. With muscular relaxants as independently applied medicines, there has disappeared the necessity for greater dozes of medicines and the risk of surgery has decreased.
