About Myoril 4 Capsule
Myoril 4 Capsule contains Thiocolchicoside 4 mg. Thiocolchicoside is a muscle relaxant. It is used for a short time, along with other treatment, to ease painful muscle spasms, such as those in the back or neck. It is meant only for adults and teenagers over 16, and for a limited number of days, because of safety concerns with longer use or higher doses.
