Answer 1

Oral antihistamines are available without a prescription. Common types such as diphenhydramine (for example, Benadryl), chlorpheniramine (for example, Chlor-Tripolon), and loratadine (for example, Claritin) are used to treat allergy symptoms and itching.

Answer 2

Antihistamines that are taken by mouth (oral) work better than those that are applied directly to the skin (topical) because a pill or capsule contains a specific dose of medicine. The dose in a cream or ointment depends on how much is applied at one time and is harder to control. Too much antihistamine absorbed through the skin can be toxic, especially to children. Don't give any antihistamines to your child unless you've checked with the doctor first. The use of cream or ointment antihistamines is not reliable and not recommended.
