K.S.
When my kids start throwing up when I give them motrin or tylenol I get them a thing called Feverall - I have found it at Walmart and I think both CVS and Walgreens carries it but it is the same meds in tylenol but in a suppositry so it goes up their butt however it works and once their fever is down they start acting better - eating and drinking too - worth a shot!! Hope he feels better quick
