If your doctor prescribed more than one rheumatoid arthritis (RA) medicine, there’s a good reason for that. One of those drugs may ease your pain, while the other helps to stop joint damage. If you’re not sure what your drugs do or why you need them, ask your doctor. Also tell your doctor if side effects or costs are problems. He or she can help you look for solutions, whether it’s another drug or help with costs, so you can keep up with your treatment.
