[Psychiatrically relevant side effects of non-psychopharmacological pharmacotherapy].

We briefly review the possibilities of side effects caused by therapy with drugs other than psychotropic agents. These complications are mainly depressive/manic, paranoid-hallucinatoric/deliriant or anxiety/panic syndromes. Especially elderly patients and patients with multiple diseases are the preferred group with these side effects, because they are most likely to show a disturbance of blood-brain barrier and renal clearance. We will discuss the psychiatrically meaningful side effects of frequently used drugs, and we will present a concept of how to reduce such unwanted side effects.
