Does lurbinectedin cause hair loss?
Lurbinectedin (Zepzelca), used for small cell lung cancer, lists alopecia (hair loss) as a common side effect in clinical trials, affecting 20-35% of patients depending on the study dose and combination.[1][2] It occurs due to the drug's interference with rapidly dividing cells, including hair follicles, similar to other chemotherapy agents.
Is the hair loss reversible?
Yes, hair loss from lurbinectedin is typically reversible. Regrowth starts 1-3 months after treatment ends, with full recovery in 3-6 months for most patients. Severity varies—mild thinning regrows faster than complete baldness—but no permanent alopecia is reported in trial data or post-marketing surveillance.[1][3]
How long until hair grows back?
- Timeline: Follicles enter a resting phase during treatment; anagen (growth) phase resumes post-treatment.
- Factors affecting speed: Younger patients, shorter treatment duration, and good nutrition accelerate regrowth. Scalp care (gentle shampoos, avoiding heat) helps.
- Patient reports note initial regrowth as fine or curly hair, normalizing over time.[4]
What if hair doesn't grow back?
Rare cases of delayed regrowth (beyond 6 months) link to ongoing treatment, nutritional deficiencies, or concurrent therapies like immunotherapy. Consult an oncologist—tests for thyroid issues or iron levels may be needed. No evidence ties lurbinectedin to irreversible damage.[2][5]
Tips to manage hair loss during treatment
Cooling caps reduce incidence by 50% in studies by constricting scalp blood flow.[6] Wigs, scarves, or minoxidil (post-treatment) aid appearance and regrowth. Avoid dyes or tight styles.
