Meloxicam is a prescription non-steroidal anti-inflammatory drug (NSAID) used for different types of arthritis pain. It comes as a capsule, tablet, or liquid that you take by mouth. It's also available as an injection that's given by a healthcare provider in a hospital setting. Common side effects include diarrhea, joint pain, and stomach upset. Like all NSAIDs, meloxicam can raise the risk for stomach bleeds.
