CeeNU (generically known as Lomustine Capsules) is a cancer medication used to treat brain tumors and Hodgkin's disease. Lomustine belongs to a class of drugs known as alkylating agents. It works by slowing or stopping the growth of cancer cells by interfering with the DNA within the cells.

The dosage adjustment of CeeNU must be considered based on nadir blood counts from prior doses as the bone marrow toxicity of CeeNU is cumulative. The drug is potent and should be used only by physicians experienced with cancer chemotherapeutic drugs.

Use and Dosage

CeeNU is available in capsule form to be taken orally as a single dose by following your doctor's instructions, usually once every 6 weeks. Swallow the capsules whole, don’t chaw, crush it down. Your dose may consist of capsules of 2 or more different strengths/colors. Take the medication on an empty stomach at least 1 hour before or 2 to 3 hours after a meal, with a full glass of water unless directed otherwise by your doctor, to avoid nausea and vomiting.

The dosage of CeeNU is based on numerous factors including your medical condition, response to treatment, body size, and lab tests. Do not increase your dose or use CeeNU more often or for longer than prescribed, as it may increase the risk of side effects and will not improve your condition any faster.

Make sure to wear rubber or latex gloves while handling the capsules, as CeeNU capsules can be absorbed through the skin and lungs. Pregnant women or women who may become pregnant should avoid handling CeeNU or breathing the dust from the capsules, as it may harm the unborn baby.
