Why is this medication prescribed?

Dasatinib is used as a first-line treatment for a specific strain of chronic myeloid leukaemia (CML; a form of white blood cell cancer) in individuals who have outgrown the benefits of other leukaemia drugs like imatinib (Gleevec) or who are unable to take these drugs due to negative effects. Children aged one year or older who have a specific kind of chronic CML may also be treated with dasatinib. Adults with a particular form of acute lymphoblastic leukaemia (ALL; a type of cancer of the white blood cells) who are no longer responding to other leukaemia drugs or who are unable to take these medications due to adverse effects can also be treated with dasatinib. A specific kind of ALL in children aged one year or older is also treated with it in conjunction with chemotherapeutic drugs. Kinase inhibitors are a group of drugs that includes dasatinib. It operates by obstructing the function of an aberrant protein that instructs cancer cells to proliferate. The spread of cancer cells is halted as a result.

How should this medicine be used?

Dasatinib is available as an oral tablet. It is typically taken once daily, with or without meals, in the morning or the evening. Take dasatinib every day around the same time. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Just as prescribed, take dasatinib. Never take it in larger or less amounts or more frequently than directed by your doctor.

Do not chew, break, or crush the tablets; instead, swallow them whole. Ask your doctor how to take dasatinib tablets if you are unable to swallow the pills whole or if you are giving this medication to a child. When handling tablets that have been accidentally crushed or broken, put on latex or nitrile gloves to avoid coming into contact with the medication.

Depending on how you respond to treatment and any adverse effects you experience, your doctor may change your dasatinib dose or temporarily or permanently cease your treatment. Discuss your feelings regarding your treatment with your doctor. Even if you feel well, keep taking dasatinib. Without first consulting your physician, do not discontinue taking dasatinib.

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at for additional information.
