How Supplied


CeeNU has been shown to be useful as a single agent in addition to other treatment modalities, or in established combination therapy with other approved chemotherapeutic agents in the following:

Brain tumors - both primary and metastatic, in patients who have already received appropriate surgical and/or radiotherapeutic procedures.

Hodgkin's disease - secondary therapy in combination with other approved drugs in patients who relapse while being treated with primary therapy, or who fail to respond to primary therapy.


The recommended dose of CeeNU in adult and pediatric patients as a single agent in previously untreated patients is 130 mg/m² as a single oral dose every 6 weeks (see PATIENT INFORMATION and HOW SUPPLIED: Directions to the Pharmacist). In individuals with compromised bone marrow function, the dose should be reduced to 100 mg/m² every 6 weeks. When CeeNU is used in combination with other myelosuppressive drugs, the doses should be adjusted accordingly.

Doses subsequent to the initial dose should be adjusted according to the hematologic response of the patient to the preceding dose. The following schedule is suggested as a guide to dosage adjustment:

Nadir After Prior Dose Percentage of Prior Dose to be Given
Leukocytes (/mm³) Platelets (/mm³)
≥ 4000 ≥ 100,000 100%
3000–3999 75,000–99,999 100%
2000–2999 25,000–74,999 70%
< 2000 < 25,000 50%

A repeat course of CeeNU should not be given until circulating blood elements have returned to acceptable levels (platelets above 100,000/mm³; leukocytes above 4000/mm³), and this is usually in 6 weeks. Adequate number of neutrophils should be present on a peripheral blood smear. Blood counts should be monitored weekly and repeat courses should not be given before 6 weeks because the hematologic toxicity is delayed and cumulative.


CeeNU® (lomustine) Capsules are available in individual bottles of 20 capsules each.

NDC 0015-3032-20 100 mg capsules (Green/Green)
0015-3031-20 40 mg capsules (White/Green)

CeeNU Capsules are stable for the lot life indicated on package labeling when stored in well-closed containers at 25°C (77°F); excursions permitted to 15°C–30°C (59°F–86°F) [see USP Controlled Room Temperature]. Avoid excessive heat (over 40°C, 104°F).

Directions to the Pharmacist

The total dose prescribed by the physician can be obtained (to within 10 mg) by determining the appropriate combination of capsule strengths. Only the appropriate number of CeeNU capsules required for a single administration should be dispensed.

The appropriate number of capsules of each size should be placed in a single vial. Each color-coded capsule is imprinted with the dose in milligrams. In order to provide the proper dose of CeeNU, patients should be aware that there may be 2 or more different types and colors of capsules in the container. Patients should be told that CeeNU is taken as a single oral dose and will not be repeated for at least 6 weeks.

Caution should be exercised when handling CeeNU Capsules. Procedures for proper handling and disposal of anticancer drugs should be utilized. Several guidelines on this subject have been published.1-4 To minimize the risk of dermal exposure, always wear impervious gloves when handling bottles containing CeeNU Capsules. CeeNU Capsules should not be broken. Personnel should avoid exposure to broken capsules. If contact occurs, wash immediately and thoroughly.
