Can I take allergy medication if I am 24 weeks pregnant?

Yes, you can take antihistamine medication for allergic reactions during pregnancy. It is recommended to use oral antihistamines such as diphenhydramine (Benadryl) in tablet form. It is safe to use at any stage of pregnancy and while breastfeeding. It is advised to start with 2 tablets together, then continue with 1 tablet every 6 hours until the skin reactions disappear. However, be cautious as this medication can cause drowsiness and dizziness. If there is no improvement after 24 hours, or if the skin reactions worsen, it is recommended to seek further medical advice. Additionally, it would be beneficial to identify the cause of the reaction by checking for any recent changes in medication, beauty products, or other substances.
