Warning: There have been some reports of Leukeran causing other forms of cancer in patients that are taking it. It is not known whether it is the patient’s medical condition or this treatment. Consult your doctor for more information.

This medication may also cause damage to the genes and birth defects. It may also make women and men sterile.

Overdose: It is very important to avoid Leukeran overdose. As all chemotherapy drugs, Leukeran can cause serious health problems including the development of other types of cancers. If you think you have taken an overdose of the drug, you should immediately contact your doctor or the poison control center nearest you. A health care provider can give you an antidote, symptomatic treatment or blood transfusion to slow or stop the toxic effects of the medication.

Missing dose: Leukeran can be taken one or several times per day. If you have been recommended to take the drug once a day and you miss a dose until the next day, do not double the dose. If you have been recommended to take medication several times a day and forgotten until the next dose, skip the missed dose; do not double the dose. Don’t ever take less or more of the prescribed dose.
