title: [Lithium, pregnancy and breast feeding].
abstract: Due to its teratogenic potential and its passage in the maternal milk, the administration of lithium during pregnancy and post-partum, if breast-feeding is contemplated, raises specific issues. The kinetics of lithium during pregnancy is reviewed, as well as its influence on the foetus during this period and during breast-feeding. Its teratogenicity affects particularly the cardiovascular system, the Ebstein's anomaly being the most typical and frequent malformation. As a general rule, the administration of lithium should be avoided during pregnancy, at least during the first trimester. However, pregnancy and breast-feeding do not represent an absolute contraindication for the continuation of lithium therapy if it is deemed necessary, in spite of the risks that can be incurred and of which the patient should be informed.
