Is it safe to use antihistamines during pregnancy?
It is generally recommended that you do not take drugs during pregnancy, including second generation antihistamines like cetirizine and loratadine. There are, however, no clinical studies that have established an incontrovertible link between antihistamines and major birth defects, specifically in the first trimester of pregnancy. Because there is no data to suggest that antihistamines cause harm to the mother or the foetus, in special cases antihistamines have been prescribed for severe urticaria in pregnant women. If you are pregnant and feel that you need to use an antihistamine, you should consult with a qualified medical practitioner before beginning treatment.
