Abstract |
The Food and Drug Administration has issued a number of advisories regarding a possible causal link between antidepressants and suicide behaviour among young persons. We investigated the age dependency of (fatal) suicide attempts associated with antidepressants (N=232,561). By linking insurance claims with the death register of Statistics Netherlands (2002-2011), rates of (fatal) suicide attempts were estimated during antidepressant use and intermittent episodes without use. The age dependency of the relative risk of attempts and of suicide during episodes with compared with episodes without antidepressants was investigated by testing the {age × episode} interaction.The attempt rate during antidepressant use decreased with increasing age, concurrently with a decrease of the relative risk from 3.62 to 1.86 (pfor interaction <0.001). This age dependency was found both at the early (<0.5 year) and at later stages after the first prescription (>5 years). No suicides were found among those aged <18 years, and no age dependency for the relative risk of suicide at ages ⩾ 18 was established (p>0.46). The association between antidepressants and suicide attempts at a young age does not necessarily point to a causal relationship, and, most importantly, did not translate to a similar age dependency for suicide.
