[/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. According to American College of Obstetricians and Gynecologists (ACOG) and The American College of Allergy, Asthma and Immunology (ACAAI) chlorpheniramine (allergex) is one of   the antihistamines of choice for pregnant women. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Olgeta Xhufka </s>
