Flexura Capsule: Uses, Dosage, Side Effects, Precautions and Alternates

Quick overview

Flexura Capsule contains Metaxalone, a muscle relaxant used to relieve pain and discomfort from sprains or other muscle injuries, often alongside rest and physical therapy. Some versions, called Flexura D, combine metaxalone with diclofenac, a pain and anti-inflammatory medicine. It works by acting on the central nervous system to relax muscles and, in the combination form, also reduces pain and inflammation.

How Flexura Capsule works
