MYOLAX PLUS 1ML is likely an injectable solution, though without specific information on its active ingredients, a precise description of its use cannot be provided. Medications labeled "PLUS" often indicate a combination of active ingredients intended to provide a synergistic or broader therapeutic effect compared to a single-ingredient product. If MYOLAX PLUS 1ML is indeed an injectable muscle relaxant, it might contain tolperisone along with another agent, such as a local anesthetic or another pain reliever, to provide both muscle relaxation and pain relief at the site of injection.
