Key takeaways
Methocarbamol (Robaxin) and carisoprodol (Soma) 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 pain. However, methocarbamol is not a controlled substance, while carisoprodol is a Schedule IV controlled substance due to its potential for misuse and dependence. Methocarbamol is typically taken three to four times a day, and it is available in both oral and injectable forms. Carisoprodol is typically taken four times a day. Methocarbamol is less likely to cause drowsiness compared to carisoprodol, which commonly causes drowsiness and dizziness. Methocarbamol does not interact with acetaminophen or ibuprofen, while carisoprodol has interactions with several medications, including omeprazole and aspirin. Additionally, methocarbamol is not habit-forming, whereas carisoprodol can lead to dependence and withdrawal symptoms if stopped abruptly.
