Loratadine oral solution is a second generation antihistamine, which is mainly used for allergic skin diseases, allergic asthma or other types of diseases. This oral solution can be taken orally for children, generally for children under 12 years of age, but it is best not to take it for children under 2 years of age, and for children over 2 years of age, it is usually taken orally 5ml once a day. However, infants under 2 years of age should be used with caution. First-generation antihistamines such as paracetamol or ketotifen can be taken orally as appropriate. Therefore, pediatric medication needs to be treated differently.
