Sodium hyaluronate is similar to the fluid that surrounds the joints in your body. This fluid acts as a lubricant and shock absorber for the joints.

Sodium hyaluronate is used to treat knee pain caused by osteoarthritis.

Sodium hyaluronate is usually given when other arthritis medications have not been effective.

Sodium hyaluronate may also be used for purposes not listed in this medication guide.

You should not receive a sodium hyaluronate injection if you have an infection in your knee or in the skin around your knee.

Sodium hyaluronate is injected directly into your knee joint. A healthcare provider will give you this injection.

Sodium hyaluronate is usually given once every week for 3 to 5 weeks. Follow your doctor's dosing instructions very carefully.

To prevent pain and swelling, your doctor may recommend resting your knee or applying ice for a short time after your injection.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Tell your doctor if your symptoms do not improve, or if they get worse.

Usual Adult Dose for Osteoarthritis:

Hyalgan: 2 mL by intra-articular injection into the knee once weekly for 5 weeks
Supartz: 2.5 mL by intra-articular injection into the knee once weekly for 5 weeks

Use: For the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics (e.g., acetaminophen)

You should not receive sodium hyaluronate if you are allergic to it, or if you have an infection in your knee or in the skin around your knee.

Sodium hyaluronate is not approved for use by anyone younger than 21 years old.

Tell your doctor if you have ever had:

• blood clots or circulation problems in your legs; or

It is not known whether sodium hyaluronate will harm an unborn baby. Tell your doctor if you are pregnant.

It may not be safe to breast-feed a baby while you are using this medicine. Ask your doctor about any risks.

Call your doctor for instructions if you miss an appointment for your sodium hyaluronate injection.

Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

For at least 48 hours after your injection, avoid jogging, strenuous activity, or high-impact sports such as soccer or tennis. Also avoid weight-bearing activity or standing for longer than 1 hour at a time. Ask your doctor how long to wait before you resume these activities.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
