What Is Euflexxa?

Euflexxa Injections Used in Viscosupplementation


Updated June 27, 2014

Definition: Euflexxa is an ultra-high purity hyaluronan, also called hyaluronic acid (HA) or sodium hyaluronate. Euflexxa is similar to healthy human synovial fluid, a substance that lubricates the joints.

Euflexxa is one of the hyaluronates used in viscosupplementation. Euflexxa is injected directly into the knee joint to restore the cushioning and lubricating properties of normal joint fluid.

Euflexxa is indicated for the treatment of knee pain in osteoarthritis of the knee in patients who have failed to respond to more conservative non-pharmacologic therapy and to simple analgesics (e.g. acetaminophen.) Use for other joints is being investigated.
