What Is Robaxin Used For?Robaxin® (methocarbamol) is a prescription muscle relaxant used to treat muscle spasms. It is approved to be used along with rest, physical therapy, and other treatments to relieve pain from acute (short-term) painful muscle spasms. The injectable form of Robaxin is also used to treat tetanus (lockjaw) in combination with other standard treatments.
A muscle spasm is an uncontrollable contraction of a muscle. Muscle spasms can cause pain, tenderness, and stiffness, and they are a frequent cause of back pain. Most often, muscle spasms are caused by injury, overuse, or similar problems (like sleeping in a strange position). Robaxin usually works quite well for these types of muscle spasms.
