1. What Hyalgan is and what it is used for

Hyalgan contains sodium hyaluronate, which is a body-specific substance that is found in the body’s joints, among other things. In the case of joint wear and tear ( osteoarthritis ), the levels of sodium hyaluronate in the synovial fluid fall. By injecting the substance directly into the joint, the body is stimulated to produce more sodium hyaluronate.

Hyalgan is used to treat mild to moderate osteoarthritis of the knee joint. The drug reduces pain and improves joint function. The effect lasts for a few months.
