question: is it safe for 2 yr old to take Benadryl and amoxicillin at the same time? and also Tylenol if fevered? she has a bad cough, tight chest and runny nose.I just gave her Tylenol and Benadryl which her doc said it was fine but have to start her on her amoxicillin tonight just need to know if its ok or should I wait a bit?..
