My 15 month old grandson takes loratdine in the morning and benadryl at night. He has eczema and his nose is always dripping in his throat, so they assume he has allergies. He thrashes in his sleep all night long. He never wakes up happy. He wakes up screaming. Can this be the medicine and should he be taking this medicine? He also takes cough medicine for the cough from the dripping in his throat. D&M decongestant thank you jackie morgan
