What side effects can Lomustine cause?

​Side Effects​Management ​
​Nausea and vomiting may occur within 45 minutes to 6 hours. May last for 24 hours.
  • Take anti-nausea/vomitng medicines if prescribed.
  • Eat small but frequent meals.
  • Avoid drinking too much water during meals.​ ​

  • Seek medical attention immediately if you or your child experience persistent vomiting.

Low white blood cell count.

May occur 4-5 weeks after the dose and persist for 1-2 weeks. White blood cells protect the body by fighting bacteria (germs) that cause infection.

To help prevent infection:

  • Wash hands regularly, especially before eating and after using the bathroom.

  • Blood in stools or urine
  • Any uncontrollable or persistent bleeding or bruising.

Low platelet counts.

May occur 4 weeks after the dose and persist for 1-2 weeks.

Platelets are important for blood clotting. With low platelets, you or your child may bruise or bleed (e.g. gums or nose) more easily than usual.

  • ​Be safety conscious.
  • Brush teeth gently with a soft-bristled toothbrush.
  • Clean your nose by blowing gently.
  • Avoid constipation by increasing fluid and fiber intake.

Loss of appetite may occur and may last for 2 to 3 days.

 

  • ​​Eat small but frequent meals.
  • Eat whenever hungry, even if it is not meal time yet.
  • If you or your child is not eating well, try some nutritional supplements such as Pediasure, Ensure and Enercal Plus.
​Pulmonary toxicity is rare but can be serious.

Effects may be delayed. Onset can occur as early as 6 months from the start of therapy or as late as 17 years after treatment.
