Direct-acting oral anticoagulants and alopecia: The valuable support of postmarketing data.

Abstract:

:Little is known about the administration of direct-acting oral anticoagulants (DOACs) and the occurrence of alopecia. Our aim was to analyse the reports of alopecia following DOAC administration received until 2 May 2018 from VigiBase, the World Health Organization database. A descriptive analysis of age, sex, seriousness and dechallenge/rechallenge outcome was carried out. For each report, the time-to-onset was evaluated and the causality was assessed by using Naranjo algorithm. Overall, 1316 reports were retrieved, most concerning rivaroxaban (58.8%); 80% of the reports were related to females, in particular to those aged ≥65 years (23.1%). The median value of the time-to-onset was 28 days, with an interquartile range of 63 days. In 54.3% of the reports the causality was assessed as possible. In conclusion, a possible association could exist between DOACs administration and alopecia, but further observational studies are needed to confirm these findings.
