CompositionLMWX 40 Injection is used to prevent blood clots in the deep veins of the legs (deep vein thrombosis) and clots that travel to the lungs (pulmonary embolism) in people at raised risk, such as after surgery or during a long illness with reduced mobility. It is a single-ingredient medicine containing enoxaparin sodium 40mg (4000 IU), which belongs to a class of medicines called low molecular weight heparins (anticoagulants).
The 40mg dose is the usual preventive dose for people having higher-risk surgery, such as hip or knee replacement, and for bedridden medical patients. Treatment of existing clots and some heart conditions uses higher, weight-based doses decided by the doctor. It is given as an injection under the skin of the tummy, usually once a day, by a healthcare professional or by you after training. Do not expel the air bubble from the pre-filled syringe, and rotate injection sites.
Moving around and doing leg exercises as soon as your doctor allows, and wearing compression stockings if advised, help reduce the risk of clots.
Before treatment, tell your doctor if you have active bleeding, a bleeding disorder, a stomach ulcer, recent stroke, eye or brain surgery, severe liver or kidney disease, uncontrolled high blood pressure, or have ever had a low platelet count with heparin, and about other medicines you take, especially other blood thinners and painkillers. Tell your doctor if you are due to have a spinal or epidural injection. Your doctor may check your platelet count. Seek urgent medical help for bleeding that will not stop, black or tarry stools, vomiting of blood, blood in the urine, a severe headache, sudden weakness or confusion, or a fall or head injury. Do not stop the treatment unless your doctor advises you to do so.
