Rasmus Huan Olsen

Rasmus Huan Olsen serves as a Clinical Associate Professor in the Department of Clinical Medicine at the University of Copenhagen's Faculty of Health and Medical Sciences, with clinical duties at Bispebjerg Hospital (Bispebjerg Bakke 23, 2400 København NV) and academic operations at Blegdamsvej 3, 2200 København N. His dual affiliation bridges clinical pharmacology practice with academic research through Region H (Capital Region of Denmark).

His research centers on pharmacovigilance and adverse drug reaction analysis, specializing in vulnerable populations including infants, breastfeeding mothers, and patients with cardiovascular or dermatological conditions. Key methodologies involve Danish national health registries and international databases like EudraVigilance, with particular focus on drug safety in pulmonology, congenital malformations, and severe cutaneous reactions. This work directly informs clinical guidelines and regulatory decisions.

Recent publications (2024-2025) demonstrate consistent registry-based investigation into real-world drug safety issues, spanning from mebendazole-associated Stevens-Johnson syndrome to hypercholesterolemia management post-cardiovascular events. His collaborative approach with the Danish Medicines Agency and epidemiological teams yields actionable insights for medication risk mitigation across multiple therapeutic areas.
