Healthy Knees

Indication
Synvisc-One^® (hylan G-F 20) is indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics, e.g., acetaminophen.

Important Safety Information
Before trying Synvisc-One, tell your doctor if you have had an allergic reaction to SYNVISC or any hyaluronan-based products; or if you have an infected knee joint, skin disease or infection around the area where the injection will be given, or circulatory problems in the legs. Synvisc-One is only for injection into the knee, performed by a doctor or other qualified health care professional. Synvisc-One has not been tested to show pain relief in joints other than the knee. Tell your doctor if you are allergic to products from birds – such as feathers, eggs or poultry – or if your leg is swollen or infected. Synvisc-One has not been tested in children, pregnant women or women who are nursing. You should tell your doctor if you think you are pregnant or if you are nursing a child. Talk to your doctor before resuming strenuous weight-bearing activities after treatment.

The side effects (also called reactions) sometimes seen after any injection into the knee, including Synvisc-One, include (<2% each): pain, swelling, heat, redness, and/or fluid build-up in or around the knee. These reactions were generally mild and did not last long, but in rare occasions these side effects were more severe. The most commonly occurring adverse events outside of the injected knee were headache, back pain, sore throat, the flu and faintness. Allergic reactions such as rash and hives have been reported rarely in association with SYNVISC.
