Key takeaways
Carisoprodol (Soma) and cyclobenzaprine (Flexeril) are both muscle relaxants used to treat muscle pain and discomfort. They are similar in that they are both prescribed for short-term relief of muscle-related conditions. However, they differ in several ways. Carisoprodol is a controlled substance due to its potential for misuse and dependence, while cyclobenzaprine is not. Carisoprodol is typically taken four times a day, whereas cyclobenzaprine is available in both immediate-release (taken three times a day) and extended-release forms (taken once a day). Both medications are available as a lower-cost generic and can cause drowsiness, dizziness, and headaches. Cyclobenzaprine may not be a good option for those over age 65 years or with liver problems. You should avoid drinking alcohol while taking either medication.
