Key takeaways
Methocarbamol (Robaxin) and tramadol (ConZip, Qdolo) are both medications used to manage pain, but they belong to different classes and have distinct uses. Methocarbamol is a muscle relaxer primarily used to treat muscle pain and discomfort, while tramadol is an opioid used for pain that isn't relieved by non-opioid medications. Methocarbamol is taken orally, typically 3 to 4 times a day, and is not a controlled substance, whereas tramadol is a Schedule IV controlled substance with a risk of misuse and dependence. Tramadol is available in both immediate-release and extended-release forms. Methocarbamol's side effects include dizziness and drowsiness, while tramadol can cause constipation, nausea, and potentially life-threatening side effects like dangerously slow breathing. Nether methocarbamol nor tramadol interacts with common pain relievers like acetaminophen (Tylenol) or ibuprofen (Advil, Motrin). Tramadol has many drug interactions, including with medications that affect serotonin levels.
