Let's take a minute to talk about your medication. 

This is Synvisc. It is designed to restore the natural cushion and lubricant in the knee. This may help relieve pain from osteoarthritis. 

Your doctor will inject Synvisc into your knee. You should ask your doctor if someone needs to drive you home. Many patients notice improvement in their knee pain about one month after the injection. Pain relief can last for up to 6 months. When your knee pain returns, you can ask your doctor about a second injection. 

After each injection, you should limit your physical activity for 48 hours. For example, do not stand for more than an hour at a time, and do not exercise. Normal walking is okay. This is important to help keep the swelling down. 

Most patients tolerate Synvisc well, but some side effects can occur. You could have pain at the injection site or in the knee. You could also have a little stiffness, swelling or warmth in or around the knee. Your doctor will tell you if it is okay to apply ice to the knee. These reactions are normal if they are mild, and should go away. 

You should call your doctor if the reactions are severe or if they get worse instead of better. Also, call if you notice any other unusual changes to your knee, leg or body. 

For best results with Synvisc, follow your doctor's advice for other helpful therapies that can improve your joint pain. Also, read the Patient Information leaflet for full information.
