enoxaparin alopecia low-molecular-weight heparin warfarin Naranjo Adverse Drug Reaction Probability Scale hair loss blood thinner

TLDR Some patients lost hair after being treated with the drug enoxaparin for a brain vein clot.

The document describes three cases where female patients with cerebral venous thrombosis developed alopecia after being treated with enoxaparin, a low-molecular-weight heparin. The patients were given 1 mg/kg of enoxaparin subcutaneously twice daily for 3 weeks, followed by oral warfarin for 6 months. Hair loss began approximately 3 weeks after the start of enoxaparin treatment and resolved within 1 month of stopping the drug. The Naranjo Adverse Drug Reaction Probability Scale indicated a score of 6, suggesting enoxaparin as the probable cause of the hair loss. The report highlights the need for awareness of this potential side effect among healthcare professionals.
