Imipramine-flupenthixol decanoate interaction

The authors describe a case in which flupenthixol decanoate and imipramine were co-administered to a patient with schizophrenia, resulting in extremely high levels of imipramine and its metabolite, desipramine. The literature on the co-administration of neuroleptics and antidepressants is reviewed and guidelines for limiting possible iatrogenic effects of the combination are suggested.
