EUFLEXXA (1% sodium hyaluronate) is used to relieve knee pain due to osteoarthritis. It is used in people who do not get enough relief from simple pain medications such as acetaminophen or from exercise and physical therapy.
What is Euflexxa?
Euflexxa is a form of hyaluronic acid (HA) and is used to relieve knee pain due to osteoarthritis. HA is a natural substance found in the fluid that surrounds a healthy knee. This fluid is called synovial fluid, and it helps cushion, lubricate, and protect the knee. In people with osteoarthritis (OA) of the knee, the synovial fluid becomes thinner and less able to do its job.
Euflexxa is similar to the HA found in healthy knees. It is a prescription, non-surgical therapy that your doctor can treat you with, during three office visits, one week apart. Euflexxa is designed to help patients who are not getting enough relief from non-prescription pain relievers or from exercise and physical therapy. When Euflexxa is injected into the knee, it helps replenish the HA in the knee and helps restore the ability of the synovial fluid to cushion, lubricate, and protect the knee.
Each 1 ml of EUFLEXXA® contains:
Sodium hyaluronate 10 mg
Sodium chloride 8.5 mg
Disodium hydrogen phosphate dodecahydrate 0.56 mg
Sodium dihydrogen phosphate dihydrate 0.05 mg
