When is HYALGAN® the right choice for me?
HYALGAN® is for the treatment of osteoarthritis knee pain, when simple painkillers (like Tylenol® or Advil®) or exercise and physical therapy are not enough. The treatment that's right for you will depend on how far your osteoarthritis has progressed, how much pain you are experiencing, and what has worked (or not worked) for you in the past.

Who should not receive HYALGAN®?
- Your health care provider will not administer HYALGAN® if you have had any previous allergic reaction to HYALGAN® or similar material; ie, other hyaluronate products
- You should not have a HYALGAN® injection into the knee if you have infections or skin diseases around the injection site
- Consult your physician if you are allergic to products from birds, such as feathers, eggs, and poultry
How soon will I get pain relief with HYALGAN®?
Pain relief varies from person to person and may depend on the severity of your pain. In medical studies, most patients noticed a difference within 1 week following the third injection. However, some patients did not get pain relief until after the 5 injections.
How long will pain relief from HYALGAN® treatment last?
Five injections given at weekly intervals can provide most patients with long-lasting pain relief for up to 6 months. The duration of pain relief you experience may vary.
Can I get pain relief with fewer than 5 injections of HYALGAN®?
Some patients may experience benefit with 3 injections given at weekly intervals. This has been noted in studies of patients receiving 3 injections who were followed for 60 days.
Will treatment with HYALGAN® be all that I need to relieve osteoarthritis knee pain?
Everybody responds differently to pain. For some people, HYALGAN® will provide all the osteoarthritis knee pain relief that's needed. Other people may get the greatest pain relief by adding HYALGAN® injections to the nonprescription or prescription medicines they're already taking. HYALGAN® has no known drug interactions, but if you have questions about other medications you may be taking, talk to your health care provider.
What are the most common side effects of treatment with HYALGAN®?
Side effects sometimes seen when HYALGAN® is injected into the knee are pain, swelling, heat, and/or redness of the joint, as well as rash, itching, or bruising around the HYALGAN® injection area. These reactions were generally mild and did not last long.
Can treatment with HYALGAN® be repeated?
Yes. HYALGAN® has been shown to be safe for repeat treatment in a 30-month study. In medical studies, 1 cycle (5 injections) of HYALGAN® treatment provided pain relief for 6 months. Because osteoarthritis is a chronic and degenerative condition, you and your health care provider can decide when it's time to repeat the treatment.
Can HYALGAN® help my knee work better?
Osteoarthritis of the knee is a chronic and degenerative condition that has no cure, but the pain can be controlled. Treatment with HYALGAN® can relieve the osteoarthritis knee pain that may be keeping you from doing the things you want to do.
