Supartz 2.5ml injection for knee osteoarthritis treatment
Sodium hyaluronate is a linear polysaccharide which is naturally present in the synovial fluid and protects and lubricates your joints during movement. Supartz is indicated for patients with osteoarthritis to treat their knee pain and inflammation. Supartz is used in osteoarthritis patients who have already tried non-pharmacologic therapies such as diet and exercise and pharmacologic therapies such as pain medications but didn’t show any improvement.
Mechanism of action:
Your knee is protected from the injuries and shocks due to the presence of synovial fluid in the knee joints. Synovial fluid acts as a lubricant and cushion with viscous and rheological properties due to the presence of sodium hyaluronate. With the loss of synovial fluid, the protection is lost and it leads to osteoarthritis and knee pain. Supartz functions similar to the synovial fluid due to the presence of sodium hyaluronate as an active ingredient and thereby it gives relief from the knee pain for up to six months.
How to use Supartz:
Supartz is a sterile and visco-supplement injection and it is injected into your knee joints by your doctor. You should never try it by yourself. The procedure is called as viscosupplementation because you are supplementing the viscous and rheological properties of Supartz to protect and lubricate your knees. Skin disinfectants which contain quaternary ammonium salts should not be used to prepare the injection site as ammonium salts can precipitate sodium hyaluronate. Any extra fluid present in the joint is removed and then Supartz is injected only into the knee joint but not into any vein or artery or tissue. A total of five injections are given consecutively for five weeks with one injection per week and it provides relief from the knee pain for up to 6 months. Pain relief after an injection differs from person to person. The dose of Supartz varies from patient to patient based on their medical condition and based on their response to the treatment. Your doctor may suggest a repeat treatment if necessary based on your condition.
Supartz side effects:
Common side effects are redness, rashes, bruises, pain, itching, swelling and effusion in and around the injected joint, nausea and tiredness, flu like symptoms, headache, numbness and overall body pains.
