[Etanercept in pregnancy and breast-feeding].
Etanercept is a biological drug, inhibitor of the Tumor Necrosis Factor indicated for the treatment of severe or moderate psoriasis resistant to other therapies. Because its use is becoming increasingly extended, we should know its possible teratogenic effects. The data provided by the literature and studies prior to the marketing of the product are very limited. Thus, it is necessary to study the presence of possible risks more through experiments in animal models and to conduct prolonged prospective studies in humans. With the current knowledge, it seems that suspension of the treatment from one month prior to becoming pregnant would provide an adequate safety margin, and that most of the patients who have become pregnant and have suspended etanercept as soon as they knew they were pregnant have not had any complications. However, the data needed to recommend etanercept for the control of psoriasis of a pregnant woman are very limited and controversial. Since the effects of a possible transfer of etanercept to maternal milk in a still-immature immune system are not known, in accordance with the risk/benefit principle, the use of etanercept should not be recommended in breast-feeding women.
