Introduction
Sonib belongs to the class of medicines known as tyrosine kinase inhibitors used in the treatment of liver cancer, kidney cancer, and thyroid cancer.
Sonib should be taken on an empty stomach, but try to have it at the same time every day to get the most benefits. 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.
Fatigue, nausea, loss of appetite, hair loss and diarrhea are some common side effects of this medicine. It might cause high blood pressure, so the doctor may ask you for a regular check-up of blood pressure. You must inform your doctor if you notice severe skin reaction such as skin rash, or any pain, swelling, and redness of your hands and feet.
Before taking it, tell your doctor if you have heart disease, liver, or kidney problems or high blood pressure. Many other medicines can affect, or be affected by, this medicine so let your healthcare team know all medications you are using. This medicine is not recommended during pregnancy or while breastfeeding. The use of effective contraception by both males and females during treatment is important to avoid pregnancy.
