Indications
Hyalgan is a synovial fluid replacement therapy used to treat knee pain caused by osteoarthritis. It is injected into the knee and contains sodium hyaluronate which acts as a lubricant and shock absorber in the joint. It works by acting as a lubricant and shock absorber in the knee joint, helping the joint to move more smoothly and reducing pain.
Sodium hyaluronate is a natural substance found in the body, and Hyalgan is made from a purified form of this substance. The treatment involves a series of injections directly into the knee joint, and the number of injections required can vary depending on the severity of the condition.
Hyalgan is typically used in patients who have not responded to conservative treatment options and have failed to find adequate pain relief. Hyalgan should only be used under medical supervision.
Uses and Dosage
Hyalgan is given by injection into the affected joint once a week. To prepare for the injection, avoid using skin disinfectants that contain ammonium salts like benzalkonium chloride. Your doctor may need to remove extra fluid from the joint before injecting the medicine.
Dosage is dependent on your medical condition and response to treatment. Avoid injecting hyaluronate into veins or arteries due to increased side effects. After receiving the injection, refrain from activities that put pressure on the knee for 48 hours. It is normal to experience increased pain and swelling in the knee after the injection, but if this persists, consult your doctor. Stay on schedule with injections, as it may take up to 3 injections before the full benefits of this medication occur.
