What does HYALURONATE INJECTION look like?
Synvisc 16mg/2 mL Intra-articular Syringe
Uses:
This medication is used to treat knee pain in patients with joint inflammation (osteoarthritis). It is usually used in patients who have not responded to other treatments such as acetaminophen, exercise, or physical therapy. Hyaluronate (also known as hyaluronan) is similar to a substance that occurs naturally in the joints. It may work by acting as a lubricant and shock absorber in the joint, helping the knee to move smoothly, thereby lessening pain.
Missed Dose
If you miss a dose, consult your doctor as soon as possible to establish a new dosing schedule.
How To Use
Read the Patient Information Leaflet provided by your health care professional before you start using hyaluronate and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Your doctor will give this medication by injection into the affected joint, usually once a week. Skin disinfectants that contain ammonium salts (such as benzalkonium chloride) should not be used to prepare the injection site. Your doctor may need to remove extra fluid from the joint before injecting the medicine. Dosage is based on your medical condition and response to treatment. Hyaluronate should not be injected into a vein or artery because increased side effects may occur. After receiving an injection of hyaluronate, you should avoid any activities that put stress on your knee (such as jogging, tennis, heavy lifting, standing on your feet for more than an hour) for 48 hours. Also, after the injection, you may experience increased pain and swelling in the knee at first. If the pain or swelling continues or worsens, talk to your doctor promptly. It is important to have this medication injected on schedule. It may take up to 3 injections before the full benefits of this medication occur. Tell your doctor if your condition persists or worsens.
Drug Interactions
The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring. To help your doctor or pharmacist give you the best care, be sure to tell your doctor or pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval. Keep a list of all the products you use.

Notes
Do not share this medication with others. Non-drug treatments for osteoarthritis include exercising, doing physical therapy, losing weight, having extra fluid removed from the knee, and avoiding activities that cause pain in your knee.
