Asperag 10000IU Injection is used in the treatment of some kinds of cancer of white blood cells (leukemia). It may also be used to treat other types of cancer as determined by your doctor. It may be used on its own, or sometimes given together with certain other medicines as part of combination chemotherapy. Asperag 10000IU Injection is given as an injection by the doctor, but try to have it the same time each day to make sure it has the best effect. Your doctor will decide what dose is necessary and how often you need to take it. This will depend on what you are being treated for and may change from time to time. You should take it exactly as your doctor has advised. Taking it in the wrong way or taking too much can cause very serious side effects. It may take several weeks or months for you to see or feel the benefits but do not stop taking it unless your doctor tells you to. The most common side effect of this medicine includes breathlessness, rash, vomiting, angioedema (swelling of deeper layers of skin), and nausea. It might cause increased blood sugar levels, hence regular blood tests are required to monitor your blood sugar levels, response to the therapy, and any side effects. It is advised that you drink extra fluids so that you pass more urine. This will help prevent bladder and kidney problems and keep your kidneys working well. This medicine may lower your body's resistance and increase susceptibility to infections. Infections can sometimes be life-threatening. It is important to use effective contraception to avoid getting pregnant or fathering a child during treatment. Before taking this medicine, inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
