INTRODUCTION

HYALGAN 20MG contains Sodium hyaluronate which belongs to the group of medicine called viscoelastic supplements. It is used to manage pain in knee osteoarthritis among patients who have failed to respond adequately to simple analgesics and conservative non-pharmacologic therapy. Sodium hyaluronate is available as a salt form of hyaluronic acid. Hyaluronic acid is a natural polysaccharide present in very high amounts in the synovial fluid (fluid surrounding the joint) and acts as a lubricant and shock absorber in between joints.

People with knee osteoarthritis suffer a very low concentration of hyaluronic acid in their synovial fluid. Intra-articular administration of HYALGAN 20MG supplements hyaluronic acid to the synovial fluid and lubricates and cushions the joint. It also provides relief from joint friction and pain. It helps in absorption of shock created from normal physical activity like walking, running, jumping etc. This medicine should only be given as an intra-articular injection (in between joints). People taking this injection, or any other visco-supplementation should be advised to avoid any prolonged (for more than an hour) or strenuous activities (like lifting heavy weights, running, jumping) within 48 hours following intra-articular injection. Before administration, remove any joint effusion if present.

The most common side effect of this medicine are injection site reactions such as joint pain, swelling, redness and warmth. Contact your doctor if these symptom bothers you. HYALGAN 20MG is not recommended for use in pregnant or breastfeeding women and children under 18 years of age. Consult your doctor before taking. Before taking this medicine, inform your doctor if you have liver disease or had it in the past. Do not take this medicine, if you have any infection or inflammation at the joint cavity. Consult your doctor before taking.

• Manages osteoarthritis of the knee

HOW HYALGAN 20MG WORKS

In people with knee osteoarthritis, intra-articular administration of HYALGAN 20MG supplements the required amount of hyaluronic acid directly into the synovial fluid. This leads to enhanced joint lubrication and absorption of shock created from normal physical activity like walking, running, cycling or jumping. As a result, friction in between joint and pain are relieved.

DIRECTIONS FOR USE

This medicine will be given to you only by an orthopedic surgeon in between the joints (intra-articular injection). Your doctor will decide the correct dose and duration for you depending upon your age, body weight and health condition. Strict aseptic condition must be followed during the process.

Before administration, remove any joint effusion if present. Do not inject this medicine intravascularly because it may lead to unwanted systemic side effects. Continue to take this medicine, as long as your doctor tells you to do so, to obtain better results.
