Synvisc Side Effects

May 18th, 2012 by Paul Jude

Synvisc (hylan G-F 20) is similar to the fluid that surrounds the joints in your body. This fluid acts as a lubricant and shock absorber for the joints.

Synvisc is used to treat knee pain caused by osteoarthritis.

Synvisc is usually given after other arthritis medications have been tried without successful treatment of symptoms.

You should not receive Synvisc if you are allergic to hylan G-F 20, or if you have an infection in your knee or in the skin around your knee.

Before you receive a Synvisc injection, tell your doctor if you have blood clots or circulation problems in your legs, or an allergy to birds, feathers, or egg products.

For at least 48 hours after your injection, avoid jogging, strenuous activity, high-impact sports, or standing for longer than 1 hour at a time.

Call your doctor at once if you have severe pain or swelling around the knee after the injection.

You should not receive Synvisc if you are allergic to hylan G-F 20, or if you have an infection in your knee or in the skin around your knee.

To make sure you can safely receive Synvisc, tell your doctor if you have:

  • blood clots or circulation problems in your legs; or
  • an allergy to birds, feathers, or egg products.

It is not known whether Synvisc will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using Synvisc. It is not known whether hylan G-F 20 passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby. Synvisc is generally not used in anyone younger than 21 years old.

Get emergency medical help if you have any of these signs of an allergic reaction to Synvisc: hives; difficult breathing; swelling of your face, lips, tongue, or throat. Call your doctor at once if you have severe pain or swelling around the knee after the injection.

Less serious Synvisc side effects may include:

  • warmth, pain, stiffness, swelling, or puffiness where the medicine was injected;
  • muscle pain, trouble walking;
  • fever, chills, nausea;
  • numbness or tingly feeling;
  • headache, dizziness;
  • tired feeling; or
  • itching or skin irritation around the knee.
