Alcohol and drugs in suicides

Background. Alcohol and drugs use were assessed in a nationwide one year suicide study in Finland. Method. Alcohol and drugs use were analysed in 1348 suicides. 96.5% of all suicides in the study year. Relative suicide risks for drugs were defined by relating the number of suicides committed by use of various drugs to drug availability. Results. Alcohol was detected twice as often in men as in women; the opposite was the case with drugs. The drugs most commonly used for suicide were neuroleptics and antidepressants, which were, in 74.3% and 77.4% of the cases, respectively, the victim's own prescribed drugs. Antidepressants were found in 19.0% of women and only 4.8% of men. Relative suicide risk for antidepressants varied substantially between different compounds. Conclusions. Undertreatment of depression is a challenge for suicide prevention. Those who commit suicide by antidepressants use their own drugs. Relative suicide risk for a drug should be considered when choosing treatment for depressive patients.
