Abstract

BACKGROUND: Intentional drug overdose is the most common method of self-harm. As psychiatric disorders are very common in self-harm patients, the medication used to treat these disorders can become the means for the self-harm act. The present study aimed at investigating an association between the use of prescribed medication (analgesics and antipyretics, anti-epileptics, antipsychotics, antidepressants and psychostimulants) as a method of self-harm and prescription rates of this medication in Flanders. We investigated the possible effect of gender, alcohol use during the self-harm act and a history of self-harm.

METHODS: Data from the multicenter study of self-harm in Flanders between 2008 and 2013 were used. The significance of differences in percentages was calculated by GEE and the strength by odds ratios (OR).

RESULTS: There was an increase in the odds of using antidepressants (0.8%) and antipsychotics (2%) among females when the rate of prescription increases. Analgesics and antipyretics (39.3/1,000) and antidepressants (124.9/1,000) were the most commonly prescribed drugs among females. Antidepressants (63.9/1,000) and antipsychotics (26.5/1,000) were the most commonly prescribed drugs among males. Antidepressants and analgesics and antipyretics were the most frequently used medications for self-harm. Analgesics and antipyretics during the self-harm act were more common among first-timers, while repeaters more commonly overdosed using antipsychotics and antidepressants.

CONCLUSION: These findings suggest that the availability of medication via prescriptions plays an important role in the choice of the medication ingested during the self-harm act. Precautions are necessary when prescribing medication, including restrictions on the number of prescriptions and the return of unused medication to pharmacies after cessation of treatment. These issues should be a focus of attention in the education and training of physicians and pharmacists.
