Lomustine

Lomustine is a chemotherapy medicine used to treat certain types of cancer. It is also sometimes known as CCNU. This page from Great Ormond Street Hospital (GOSH) explains what lomustine is, how it is given and some of the possible side effects. Lomustine is given by mouth in the form of a capsule.

Anti-sickness medicines can be given to reduce or prevent these symptoms. Please tell your doctor or nurse if your child’s sickness is very bad or continues for more than a few days.

It is possible that your child may ‘go off’ food and their appetite may reduce while having treatment. The dietitians may be able to suggest ways of making food more attractive to your child.

There will be a temporary reduction in how well your child’s bone marrow works. This means your child may become anaemic (reduced red blood cells), bruise or bleed more easily than usual, and have a higher risk of infection.

Your child’s blood counts will be checked regularly to see how the bone marrow is working. Please tell your doctor if your child seems unusually tired, has bruising or bleeding, or any signs of infection, especially a high temperature.

Your child may lose some or all of their hair, including eyebrows and eyelashes. This is temporary and the hair will grow back once the treatment is finished.

Your child may get painful or bleeding gums, ulcers or a sore mouth. You will be given advice about appropriate mouth care including a copy of our leaflet. If your child complains of having a sore mouth, please tell your doctor or nurse.

Lomustine can cause some mild changes to your child’s liver function. This should return to normal when the treatment is finished. Blood tests (LFTs) may be taken to monitor your child’s liver function. Please contact your doctor immediately if your child complains of pain in their right side or the whites of their eyes or their skin develops a yellow tinge.

Some medicines can react with lomustine, altering how well it works. Always check with your doctor or pharmacist before giving your child any other medicine, including medicines on prescription from your family doctor (GP), medicines bought from a pharmacy (chemist) or any herbal or complementary medicines.

You can mix the medication with ice cream, yoghurt or similar food like chocolate mousse, as below. You should do this away from bright sunlight.

• If you accidentally spill the tablets or mixture medicines on the work surface or floor, wearing gloves, cover the spillage with kitchen paper. Wipe the area with water then clean with household cleaner and water. 
• If the mixture gets onto your skin, you must wash the area immediately, using plenty of water. If the skin is sore you should contact your GP (family doctor) for advice.
• If the mixture accidentally gets into your eyes, wash with plenty of running water for at least 10 minutes. If your eyes are sore after this, you should go to your nearest Accident and Emergency (A&E) department.
• If the mixture is spilt on clothing, the spill should be blotted dry with kitchen paper. Clothing should be removed immediately and washed separately from other items. Used kitchen paper should be disposed of as above.
• Used paper towels, masks, vomit and dirty disposable nappies should be placed inside two rubbish bags and disposed of along with your normal rubbish.

• Keep all medicines in a safe place where children cannot reach them.
• Lomustine should be kept in a cool, dry place away from direct sunlight or heat.
• You should handle these medicines with care, avoiding touching them where possible. If you are pregnant or think you could be pregnant, please discuss handling instructions with your doctor, nurse or pharmacist. Please see our Special handling requirements information sheet for further details.
• If your child vomits straight after taking the dose, inform your local doctor or nurse, as your child may need to take another one. Do not give them another dose without informing the doctor or nurse.
• If you forget to give your child a dose, do not give a double dose. Inform your doctor or nurse and keep to your child’s regular schedule.
• If your doctor decides to stop treatment with lomustine or the medicine passes its expiry date, return any remaining tablets to the pharmacist. Do not flush them down the toilet or throw them away.
