Rydapt Overview

Reviewed: May 4, 2017
Updated: 

Rydapt is a prescription medication used with other chemotherapy drugs to treat certain types of acute myeloid leukemia (a type of cancer of the white blood cells) in adults. Rydapt is also used to treat certain types of mastocytosis (a blood disorder in which there are too many mast cells, a certain kind of white blood cells) in adults.

Rydapt belongs to a group of drugs called kinase inhibitors. These work by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of mast and cancer cells.

This medication comes in a capsule form and is taken orally twice daily, with food.

Common side effects of Rydapt include nausea, vomiting, diarrhea, and headache.

Rydapt Interactions

Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your doctor if you take:
