Cyclobenzaprine is an effective muscle relaxant used to treat muscle spasms. It is particularly beneficial for short-term relief of acute muscle pain, often prescribed after injuries or for conditions like fibromyalgia. The medication works by influencing the central nervous system, helping to reduce muscle tightness and improve mobility. Although cyclobenzaprine can be very effective, it should be used with caution, especially in older adults who may be more sensitive to its side effects. Common side effects include drowsiness and dry mouth. It's crucial to follow the prescribed dosage and consult with a doctor for any concerns.
