Dear Madam, Hi & Welcome. There is no need to worry as Loratadine has no teratogenic potential. Studies in animals have failed to reveal evidence of teratogenicity or embryotoxicity. It is a pregnancy category B1 drug which has been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. For the symptomatic relief of cold I would recommend nasal decongestants like Oxymetazoline or Xylometazoline nasal drops or nasal spray. Hope this would help you.
