Hyalgan is a solution of sodium hyaluronate. Hyaluronate is a natural chemical found in the body.
Hyalgan is injected directly into the knee joint to restore the cushioning and lubricating properties of normal joint fluid.
Hyalgan is used to relieve knee pain due to osteoarthritis, for those who failed to respond to simple painkillers, exercise or physical therapy.
Hyalgan injections are typically given once a week, one week apart, for a total of five injections. Some may benefit with only three.
Hyalgan is considered a treatment or therapy, not a drug.
