Lomustine is used to treat certain types of brain tumors. Lomustine is also used with other medications to treat Hodgkin's lymphoma (Hodgkin's disease) that has not improved or that has worsened after treatment with other medications. Lomustine is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in your body.

⏳ Availability & generic status
This product is an FDA-approved generic. Other versions of the same drug are listed under Therapeutic equivalents, least expensive first.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

🚨 Boxed Warning ▾
WARNING: DELAYED MYELOSUPPRESSION and RISK OF OVERDOSAGE DELAYED MYELOSUPPRESSION Lomustine Capsules cause myelosuppression including fatal myelosuppression. Myelosuppression is delayed, dose-related, and cumulative; occurring 4 to 6 weeks after drug administration and persisting for 1 to 2 weeks. Thrombocytopenia is generally more severe than leukopenia.
Cumulative myelosuppression from Lomustine Capsules is manifested by greater severity and longer duration of cytopenias. Monitor blood counts for at least 6 weeks after each dose. Do not give Lomustine Capsules more frequently than every 6 weeks [see Warnings and Precautions (5.1) , Dosage and Administration (2.2 , 2.3) ].
RISK OF OVERDOSAGE PRESCRIBE, DISPENSE, AND ADMINISTER ONLY ENOUGH CAPSULES FOR ONE DOSE. Fatal toxicity occurs with overdosage of Lomustine Capsules. Both physician and pharmacist should emphasize to the patient that only one dose of Lomustine Capsules is taken every 6 weeks [see Dosage and Administration (2.1) , Warnings and Precautions (5.2) , Overdosage (10) ].

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Do not breastfeed. (8.2)
8.1Pregnancy Risk Summary Based on animal data and its mechanism of action, Lomustine Capsules can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ]. There are no available data on Lomustine Capsules exposure in pregnant women. Lomustine was teratogenic in rats and embryotoxic in rabbits at total dose levels approximately two to four times the total human dose of 130 mg/m 2 over 6 weeks (0.18 to 0.27 times the single human dose of 130 mg/m 2 ) based on BSA [see Data] .
Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Lomustine was administered by intraperitoneal injection daily to pregnant rats during the period of organogenesis at dose levels of 0, 2, 4, 6, and 8 mg/kg.
Resorption rates and post-implantation loss occurred at doses greater than or equal to 4 mg/kg (approximately 0.18 times the clinical dose of 130 mg/m 2 based on BSA or approximately twice the total clinical dose of lomustine over 6 weeks). Malformations (omphalocele, ectopia cordis, scoliosis, syndactyly, hydrocephalus, microphthalmia, anophthalmia, anomalies of aortic arch, dextrocardia, malpositioning of the ovaries and testes, sternoschisis, and shortened/misshapen bone of the fore or hind limbs) and decreased fetal body weight occurred at all dose levels.
In pregnant rabbits treated with lomustine at 3 mg/kg (approximately 0.27 times the 130 mg/m 2 clinical dose based on BSA or approximately four times the total clinical dose of lomustine over 6 weeks) during organogenesis, there were increases in abortions and decreases in surviving pup weight that persisted postnatally.
8.2Lactation Risk Summary There is no information on the presence of lomustine or its metabolites in human milk, its effects on the breastfed infant, or its effects on milk production. Because of the potential for serious adverse reactions in breastfed infants from Lomustine Capsules, advise women not to breastfeed during treatment with Lomustine Capsules and for 2 weeks after the final dose.
8.3Females and Males of Reproductive Potential Contraception Females Based on animal data and its mechanism of action, Lomustine Capsules can cause fetal harm [see Use in Specific Populations (8.1) ]. Advise females of reproductive potential to use effective contraception during treatment and for 2 weeks after the final dose. Males Based on Lomustine Capsules's mechanism of action, advise males with female partners of reproductive potential to use effective contraception during treatment with Lomustine Capsules and for 3.5 months after the final dose [see Clinical Pharmacology (12.1) ].
Infertility Based on animal findings and its mechanism of action, Lomustine Capsules may result in reduced fertility in males and females of reproductive potential [see Nonclinical Toxicology (13.1) ].
8.4Pediatric Use Pediatric use, including dose, is not based on adequate and well-controlled clinical studies.
8.5Geriatric Use No data in the clinical studies of Lomustine Capsules are available for patients 65 years of age and over to determine whether they respond differently than younger patients. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.
Lomustine and its metabolites are known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and ren…
