Tell your doctor if you have ever had an allergic reaction to metaxalone, any of the active or inactive ingredients in metaxalone tablets, or any other drugs. Your pharmacy can give you a list of ingredients.
Give your doctor and pharmacist a complete list of your medications, including prescription drugs, over-the-counter medicines, dietary supplements, vitamins, and herbal remedies. This can help avoid potentially dangerous drug interactions.
Check all medicine labels to see if they contain metaxalone. This medication may be present in combination products with other medicines. Taking multiple products containing metaxalone can put you at risk of an overdose.
Give your doctor a complete medical history. Metaxalone may not be safe for people with certain medical conditions, including blood disorders such as low red blood cells, kidney disease, liver disease, or seizures.
Inform your doctor if you are pregnant, might be pregnant, are planning a pregnancy, or are breast-feeding a nursing baby. It is unclear if this drug can harm an unborn baby or if it passes into breast milk.
If you are age 65 or above, talk to your doctor about the potential benefits versus risks of taking metaxalone. There may be other safer muscle relaxants available for older adults.
