Gelsyn-3

Indications

Gelsyn-3 is a treatment for knee pain caused by osteoarthritis (OA).

Gelsyn-3 is a next-generation hyaluronic acid (HA) that is indicated for patients who have not responded adequately to conservative non-pharmacologic therapy and simple analgesics.

Gelsyn-3 is used when other arthritis medications have not been effective in relieving knee pain.

Gelsyn-3 is one of several hyaluronic acid derivatives used for the treatment of knee osteoarthritis, along with other products like SUPARTZ FX and DUROLANE.

Use and Dosage

Gelsyn-3 is injected directly into your knee joint. A healthcare provider will give you this injection.

Gelsyn-3 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.
