When i was a baby an allergies exam results was that i was allergic to aines and some other components in advil (ibuprofen). at 21 do i have the same allergies?

Allergies: Hard to tell if you still have them or not, as some allergies tend to be outgrown whereas others don't. It will require allergy testing to determine your current status.

Probably not: Most babies outgrow their allergies by age 3 and they change constantly during that time which is why we rareloy test them unless it it might be life threatening. It would be worth your while to challenge it.You might have Benadryl (diphenhydramine) on hand just in case you react.
