Cancer Home > Ontak Dosage
Before your healthcare provider gives you Ontak, he or she will calculate an appropriate dosage based on factors like your weight and how much medicine you may need to treat your lymphoma. The drug is slowly injected into a vein once a day for five days. This five-day treatment is repeated every three weeks for eight cycles, unless you develop potentially serious reactions.
An Introduction to Dosing With OntakThe dose of Ontak® (denileukin diftitox) your healthcare provider recommends will vary, based on a number of factors, including:
- Your weight
- Your healthcare provider's impression of how much medicine you may need to treat your condition.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
What Is the Recommended Ontak Dosage?The usual recommended dosage of Ontak for treating cutaneous T-cell lymphoma is 9 or 18 micrograms (mcg) per kg body weight (about 4.09 or 8.18 mcg per lb) given once a day for five days in a row. This five-day treatment is normally given every 21 days for eight cycles, as long as potentially serious side effects do not occur.
You will be given acetaminophen (Tylenol® and others) and an antihistamine, such as diphenhydramine (Benadryl® and others), before each dose. These medicines are given to reduce your risk of developing a potentially serious reaction to the Ontak infusion.
Your healthcare provider will check your blood levels of albumin (a protein found in the body) before each dose. If the levels are too low, your treatment will be temporarily interrupted until the levels return to normal.
