Specific Synvisc Warnings and Precautions
Warnings and precautions to be aware of prior to taking Synvisc include the following:
- If you are allergic to any bird products, such as feathers or eggs, you might also be allergic to Synvisc, since it is made from chicken combs.
- Your healthcare provider should not inject any medications (such as steroids or anesthetics) into the knee joint along with Synvisc, as this would dilute Synvisc and make it less effective. It is okay for your healthcare provider to inject a local anesthetic to help numb the area prior to the injection.
- In the United States, Synvisc is not approved for injection into any other joint except the knees.
- This product should not be injected into the bloodstream or anywhere else except the knee joint.
- Synvisc should be used with caution if you have swelling of the leg, ankle, or foot.
- It is unknown if Synvisc passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Synvisc and Breastfeeding).
- It is not known if Synvisc is safe for use during pregnancy (see Synvisc and Pregnancy).
