Symptoms of an allergic reaction to Synvisc include hives; difficulty breathing; and swelling of the face, lips, tongue or throat. Patients who display any of these symptoms should seek immediate medical attention, advises RXList

Synvisc is one of several versions of hyaluronan injections used to treat osteoarthritis in the knee. It is injected directly into either both knees or a single knee joint, says Healthline. This gel-like substance mimics a substance that occurs naturally in the joints, and provides lubrication and allows the bones to move more smoothly. Synvisc does not reverse the damage or slow the progression of arthritis, even though it relieves pain and discomfort in the knee.

This drug is only approved for the treatment of mild to moderate knee arthritis. Patients usually experience pain relief by four to 12 weeks, and the effects of the injection can last for several months, explains WebMD.
