Antidepressants have been associated with a low incidence of idiosyncratic hepatic injury. Some of them, nefazodone or amineptine, were observed to induce severe hepatic injury and withdrawn from the market. Recently, some cases of this severe condition have been reported in association with agomelatine use. Therefore, the objective of this study is to learn the risk of hepatic damage with agomelatine as compared with other new antidepressants. We took data from the Spanish, French, Italian, and Portuguese pharmacovigilance system databases. A case/noncase approach to assess the strength of the association between whichever antidepressant and hepatotoxicity was performed; cases were defined as reports of hepatotoxicity; noncases were reports of all reactions other than hepatotoxicity. Exposure was the recording of a new antidepressant in a report, whether or not it was suspected of causing the reaction. During the period surveyed, 3300 cases of hepatotoxicity were collected for the antidepressants assessed. They represent 10.3% of all cases collected for these drugs; the corresponding figure for all drugs was 6.0%. Meanwhile, 63 cases of hepatotoxicity associated with agomelatine were collected since its introduction until the end of the period studied; they account for a percentage of 14.6. Agomelatine was statistically associated with hepatotoxicity in Spain [reporting odds ratio (ROR), 4.9 (95% confidence interval [CI], 2.4-9.7)], France (ROR, 2.4 [95% CI, 1.5-3.7]), and Italy (ROR, 5.1 [95% CI, 1.7-14.0]). Current results support the idea of agomelatine to be related to a higher hepatotoxicity risk. Physicians should consider early discontinuation if the condition is suspected; health authorities should promptly explore the best regulatory actions to be taken.
