Claritin didn't work for either of my kids alone, so we tried Zyrtec and also no dice. So now both are on singulair for seasonal allergies. DS needed more so he is also on claritin in the mornings (singulair before bed). This combo is working well for him. For DD she has an inhaler along with the singulair for coughing. We only use the inhaler as needed, though she hasn't been formally diagnosed as asthmatic, she just has an asthmatic cough but no breathing issues.
