How does this medication work? What will it do for me?
Hyaluronic acid belongs to the group of medications known as synovial fluid replacements. It is used to relieve the symptoms of osteoarthritis (a condition causing joint "wear and tear" and pain) in the hip, knee, and shoulder joints. It works by mimicking the body's own synovial fluid (a fluid that lubricates and cushions the joints). Pain relief can last for 6 to 12 months after the injection schedule.
