My 6 y.o. son is on Zyrtec 10 mg for severe allergies but he has stomach pains that start in afternoon and by bedtime he is nauseaus and the pain is so bad he can't sleep and then is tired and gets in trouble at school. Taken him off and stomach has subsided mostly but still comes and goes, also on Pulmicort.
