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, such as swelling of the face, tongue or throat, respiratory difficulty, rash, itching or hives to SYNVISC or any hyaluronan-based products. Allergic reactions, some which can be potentially severe, have been reported during the use of Synvisc-One. Should not be used in patients with an infected knee joint, skin disease or infection around the area where the injection will be given, and should be used with caution when there is swelling of the legs due to problems with venous stasis or lymphatic drainage.
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 (≤ 21years old), 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 sometimes seen after Synvisc-One include (<2% each): pain, swelling, heat, redness, and/or fluid build-up in or around the knee. Tell your doctor if you experience any side effects after treatment with Synvisc-One.
