  • A prescription medication, Synvisc injections contain a combination of chemicals known as Hylan GF-20. Doctors commonly prescribe injections of Synvisc for the treatment of osteoporosis in knee joints.

    Identification

    The Hylan G-F20 chemical in Synvisc is a type of sugar that comes from the combs of roosters. The medication comes in pre-measured doses for injection and is clear in color.

    Function

    Osteoarthritis of the knee occurs when the cartilage, or tissue, in your knee joint is damaged, causing pain and inflammation. Synvisc functions as a lubricant for your knee joint and helps alleviate this pain, the Mayo Clinic says.

    Features

    Doctors typically restrict use of Synvisc injections to instances in which patients have not received relief from their symptoms when using other treatments such as rest and the use of non-steroidal anti-inflammatory medications or acetaminophen (Tylenol).

    Time Frame

    Doctors typically administer one injection of Synvisc weekly for three weeks, according to RxList.

    Side Effects

    Side effects of Synvisc injections include pain and swelling at the site of the injection, reports RxList. Sometimes, this swelling is caused by the accumulation of fluid in the knee joint and requires draining.
