Certain cancers can be treated with clofarabine powder, particularly acute lymphoblastic leukaemia (ALL), which can affect both children and adults. It is a member of the purine analogue drug subclass. The chemotherapy drug clofarabine works by preventing cancer cells from reproducing their DNA, which ultimately causes the cancer cells to die. It is often given intravenously in a medical facility or clinic. Clofarabine powder is frequently administered along with corticosteroids to help prevent this condition. It is sold as an injection-ready solution. This substance is usually given once a day for five days straight. Depending on how well you respond to the medication, this dose cycle may be repeated once every two to six weeks.
