What are the side effects of Synvisc?
Synvisc® (hylan G-F
20) is an injectable drug used to treat people with osteoarthritis of the knee. It thickens the
fluid inside the joint to its natural shock-absorbing consistency. This helps to prevent pain
and stiffness in the joint. Doctors prescribe it when nondrug treatments, nonprescription
drugs, and other prescription drugs don't work. The most commonly reported side effects of
Synvisc® are mild pain or swelling caused by the injection. These effects usually go away
within three days after the injection. To lessen side effects, don't do any strenuous or
weight-bearing exercises immediately after receiving your shot. Allergic reactions or damage to
the joint occur rarely. Also, there are a few reported cases of gout in the knee occurring
after an injection of Synvisc®. If you have allergies to feathers, eggs, or other bird
products, you should tell your doctor before using Synvisc®. Promptly report any symptoms of an
allergic reaction to your doctor. Such symptoms might include a rash, itching, or trouble
breathing. People with infections in their joints should not get Synvisc® injections.
