Allergy Medicine on Hold

We had begun giving Evan zyrtec each night after talking with his Pediatrician and ENT Physician about the possibility he may have allergies. We started out with the highest dose we were told to give and it really seemed to affect his disposition in that he was more tired, whiny and an unhappy child. So we dropped it back to the lowest dose and things did not improve. So we have now stopped giving it to him all together and thing have really started to improve over the last week. He is a much happier little boy in the mornings and evenings. So we will talk with the Doctor again when we go back this month for his 2 year check-up.
