EUFLEXXA (1% sodium hyaluronate) is a hyaluronic acid (HA) product that is manufactured through a precise, multistep cleansing and filtering process that creates a highly purified, gel-like HA fluid. Unlike other HAs, EUFLEXXA is not derived from birds and is instead naturally created in a controlled environment. EUFLEXXA is designed for injection into the knee to help replace your knees own HA.
HA is a natural substance that is found in the human body as well as in animals and bacteria. In the human knee, HA is a thick, slippery fluid that helps cushion, lubricate, and protect the bones and joint tissue. In patients with osteoarthritis (OA) of the knee, the HA gets thinner over time and becomes less able to provide protection.3
EUFLEXXA is used to relieve OA knee pain in people who do not get enough relief from simple pain medications such as acetaminophen, ibuprofen, or naproxen or from exercise and physical therapy.2
When EUFLEXXA is injected into the knee, it temporarily replenishes the HA you have lost while stimulating the knee to produce its own healthy HA.4,5 Clinical studies have shown that EUFLEXXA may help provide pain relief for up to 6 months.
