The following medications can be taken to relieve allergies in infants: 1. Give children cetirizine syrup, which is an antihistamine and belongs to the second generation of antihistamines, and can play a good role in improving the symptoms of hives and allergic rhinitis caused by infants’ allergies. 2. Give children loratadine, which is also a second generation of antihistamines and will not cause drowsiness in infants. Other anti-allergy medications, such as oral prednisone, can be given to children. If the infant’s allergy symptoms are very obvious and do not improve after the application of cetirizine or loratadine, oral prednisone should be given to the infant to combat the allergy.
