Uses For bosutinib
Bosutinib is used to treat chronic myeloid leukemia (CML) that is Philadelphia chromosome-positive (Ph+). Leukemia is a type of cancer where the body makes abnormal white blood cells.
Bosutinib is an antineoplastic (cancer) medicine. It interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal cells may also be affected by bosutinib, other side effects can occur. Before you begin treatment, talk to your doctor about the benefits of bosutinib as well as the possible risks of using it.
bosutinib is available only with your doctor's prescription.
Before Using bosutinib

Tell your doctor if you have ever had any unusual or allergic reaction to bosutinib or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Proper Use of bosutinib
Take bosutinib exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.

Ask your doctor which stomach medicines are safe for you to take. Wait at least 2 hours before or after you take bosutinib. Do not take a proton pump inhibitor (PPI).

Precautions While Using bosutinib
It is very important that your doctor check your progress at regular visits to make sure that bosutinib is working properly. Blood tests may be needed to check for unwanted effects.
Using bosutinib while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during therapy and for at least 30 days after the last dose. If you think you have become pregnant while using bosutinib, tell your doctor right away.
Bosutinib can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
Check with your doctor right away if you have stomach pain, pale stools or dark urine, loss of appetite, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Cancer medicines can cause diarrhea, nausea, vomiting, or stomach pain, even after receiving medicines to prevent it. Ask your doctor or nurse about ways to control these side effects.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
