Hylasto S injection contains an active ingredient called Sodium Hyaluronate, which belongs to the group of medicines called "intra-articular agents." It is like the natural fluid that cushions your joints, which helps lubricate and protect your joints, acting as a shock absorber. This medicine relieves knee pain in patients with osteoarthritis (OA). It is usually given to patients who have not responded well to the other arthritis medications. 

Do not use Hylasto S injection if you are allergic to Sodium Hyaluronate or any of its ingredients. Do not use this medication if you have an infection in your knee or in the skin around your knee. Before taking the medicine, notify your doctor if you have had a history of blood clots or circulation issues in your legs or if you have an allergy to birds, feathers, or egg products. Report to your doctor if you have pre-existing chondrocalcinosis (cartilage calcification). Not recommended for children aged 21 years and younger as its safety and effectiveness have not been proven.

Before starting to take the Hylasto S injection, inform your doctor if you are pregnant, planning to get pregnant, or think you may be pregnant or breastfeeding. Notify your doctor if you have a history of any disease. The common side effects of the medicine are pain, redness, stiffness, bruising, or puffiness at the injection site, nausea, stomach pain, trouble walking, back pain, joint pain, muscle pain, numbness or tingling, headache, dizziness, and a runny or stuffy nose.

Treatment for osteoarthritis.

Hylasto S injection works by providing extra lubrication and cushioning to the knee joint affected by osteoarthritis. It helps reduce friction and protect the joint, which can ease pain and improve movement. The injection replenishes the natural fluid in the joint, providing relief and support for better knee function.

Hylasto S injection will be administered to you by a healthcare professional in a hospital setting. Do not self-administer. It is usually administered into the knee joint. Your doctor will decide the dose, route of administration, and frequency based on your disease condition and other factors.
