How Supplied


Hyalgan® is indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative nonpharmacologic therapy, and to simple analgesics, e.g., acetaminophen.


No information provided.

Sodium Hyaluronate 20.0 mg
Sodium chloride 17.0 mg
Monobasic sodium phosphate • 2H20 0.1 mg
Dibasic sodium phosphate • 12H20 1.2 mg

Directions For Use

Hyalgan® is administered by intra-articular injection. A treatment cycle consists of five injections given at weekly intervals. Some patients may experience benefit with three injections given at weekly intervals. This has been noted in studies reported in the literature in which patients treated with three injections were followed for 60 days.

Precaution: Do not use Hyalgan® if the package is opened or damaged. Store in the original packaging (protected from light) below 77° F (25° C). DO NOT FREEZE.

Precaution: Strict aseptic administration technique must be followed.

Warning: Do not concomitantly use disinfectants containing quaternary ammonium salts for skin preparation because hyaluronic acid can precipitate in their presence.

Inject subcutaneous lidocaine or similar local anesthetic prior to injection of Hyalgan®.

Precaution: Remove joint effusion, if present, before injection of Hyalgan®.

Do not use the same syringe for removing joint effusion and for injecting Hyalgan®.

Take care to remove the tip cap of the syringe and needle aseptically.

Inject Hyalgan® into the joint through a 20-gauge needle.

Precaution: The vial/syringe is intended for single use. The contents of the vial must be used immediately once the container has been opened. Discard any unused Hyalgan®. Inject the full 2 mL in one knee only. If treatment is bilateral, a separate vial should be used for each knee.
