Cancer Home > CeeNU Side Effects
Because CeeNU is an older medication, the specific side effects and how frequently they occur have not been extensively studied. However, possible reactions may include nausea, vomiting, and loss of appetite. Serious complications may also occur, such as fever, unusual bleeding, or mental confusion, which will require prompt medical attention.
An Introduction to CeeNU Side EffectsAs with any chemotherapy medicine, CeeNU® (lomustine) can cause side effects. In fact, most people will experience some type of reaction to this drug, and some side effects can be quite significant. Talk to your healthcare provider about ways to prevent or lessen reactions to this medicine.
(This article covers many, but not all, of the possible side effects with CeeNU. Your healthcare provider can discuss a more complete list with you.)
Common Side Effects With CeeNUFor many medications, the prescribing information carefully explains the exact percentage of side effects that were reported in clinical trials. However, the prescribing information for almost all older medications, including CeeNU, includes only vague information on potential side effects, with no exact information on how frequently the reactions may occur. Therefore, it can be difficult to know exactly how common they may be.
Based on available information, some of the more common CeeNU side effects may include:
- Nausea and vomiting (see Chemotherapy and Nausea)
- Loss of appetite
- A decrease in white blood cells, which could increase the risk for infections (see Chemotherapy and Infections)
- A decrease in platelets, which could increase the risk for bruising and bleeding (see Blood Clotting Problems and Chemotherapy)
- Anemia (see Chemotherapy and Anemia)
- Lung problems
- Mouth sores or ulcers (see Mouth and Gum Problems During Chemotherapy)
- Hair loss (see Chemotherapy and Hair Loss)
- Problems with vision, such as blurred vision or problems with peripheral vision
- Problems with balance or coordination.
Nausea and vomiting from CeeNU may occur 3 to 6 hours after your dose, and usually lasts less than 24 hours. Loss of appetite may last for several days after your dose.
