EUFLEXXA® is an injectable solution made of highly purified sodium hyaluronate that has a high molecular weight of 2.4 to 3.6 million daltons, in phosphate-buffered saline. This sterile, viscoelastic solution helps to lubricate knee joints affected by osteoarthritis. After removing any joint effusion, inject EUFLEXXA® into the synovial space in the knee. Usually you would administer a 2ml dose of EUFLEXXA® once a week for three weeks, for a total of three injections, to give maximum effect. However, you should only use each EUFLEXXA® syringe once. Your patients can experience reduced osteoarthritis pain in their knee after a set of EUFLEXXA® injections along with greater mobility and flexibility. Only qualified medical personnel should administer EUFLEXXA®.
