[Drug combinations of lithium: reasons and limitations].

Lithium is widely used in the treatment of several psychiatric diseases-bipolar mood disorder, in particular. It is often necessary to have lithium combined with other psychopharmacological agents when efforts are aimed at either enhancing a less-than-optimal therapeutic effect or treating other symptoms as well. A therapist should be familiar with every possibility, limitation, and probable risk such pharmacological combinations are likely to lead to.
