Adverse drug reactions to self-medication: a study in a pharmacovigilance database.

Although self-medication is widely developed, there are few detailed data about its adverse drug reactions (ADRs). This study investigated the main characteristics of ADRs with self-medication recorded in the Midi-Pyrénées PharmacoVigilance between 2008 and 2014. Self-medication included first OTC drugs and second formerly prescribed drugs later used without medical advice (reuse of previously prescribed drugs). Among the 12 365 notifications recorded, 160 (1.3%) were related to SM with 186 drugs. Around three-forth of the ADRs were 'serious'. Mean age was 48.8 years with 56.3% females. The most frequent ADRs were gastrointestinal and neuropsychiatric and main drug classes involved NSAIDs, analgesics, and benzodiazepines. Phytotherapy-homeopathy accounted for 9.1% of drugs.
