Drugs associated with reversible cerebral vasoconstriction syndrome: A pharmacovigilance study in vigiBase.

Background: Data on drug-induced reversible cerebral vasoconstriction syndrome (RCVS) are scarce. We aimed to describe RCVS characteristics with drugs previously identified as associated with RCVS and investigate potential signals related to other drugs.

Methods: VigiBase was queried for all reports of RCVS until 31 May 2023.

Drug-induced hearing loss: a case/non-case study in the French pharmacovigilance database.

Hearing loss is defined as a decrease in the ability to perceive sounds which can occur suddenly or gradually and affects one ear or both. It is related to various etiologies, in particular drugs. The identification of all drugs that could be associated with hearing loss is essential for the patients' life quality.
