Pregnancy and Lactation
Use loratadine with caution during pregnancy.
The manufacturers note that it is preferable not to use this medication pregnancy.
Although it is not known if loratadine crosses the human placenta, the molecular weight, about 383, is low enough for passage to the foetus to be expected.
There is no evidence of increased teratogenicity in animals or humans. Human experience indicates that loratadine, in line with other antihistamines, is not a major human teratogen. If an oral antihistamine agent is required during pregnancy, first generation agents such as chlorpheniramine or tripelennamine should be considered. However, loratadine and cetirizine are acceptable alternatives, except during the 1st trimester, if a first-generation drug was not tolerated.
Use loratadine with caution during breastfeeding.
The manufacturers note that this medication is not recommended during breastfeeding.
Loratadine and its metabolite, descarboethoxyloratadine, are excreted into human milk.
