What is the best allergy medicine for your child?

Varies. Each child may respond differently to allergy medicines, all of the second generation antihistamines can be effective. These include loratadine, Cetirizine and fexofenadine. Each medication is dosed once daily and causes minimal sedation or behavioral effects.
Depends. There are many allergy medications available for children. New generation antihistamines such as zyrtec, allegra, claritin, xyzal, (levocetirizine) and clarinex, are very well tolerated and effective. Nasal steroid sprays are more effective and Nasonex is approved to age 2 years old. Singulair is approved for allergies as well as asthma. With all of these options, there is a good fit for almost all children.
