This medication is used to treat knee pain in patients with joint inflammation (osteoarthritis). It is usually used in patients who have not responded to other treatments such as acetaminophen, exercise, or physical therapy. Hyaluronate (also known as hyaluronan) is similar to a substance that occurs naturally in the joints. It may work by acting as a lubricant and shock absorber in the joint, helping the knee to move smoothly, thereby lessening pain.
After receiving an injection of hyaluronate, you should avoid any activities that put stress on your knee (such as jogging, tennis, heavy lifting, standing on your feet for more than an hour) for 48 hours.
Also, after the injection, you may experience increased pain and swelling in the knee at first. If the pain or swelling continues or worsens, talk to your doctor promptly.
It is important to have this medication injected on schedule. It may take up to 3 injections before the full benefits of this medication occur.
Tell your doctor if your condition persists or worsens.
