Could use your help docs! my dad accidentally took 1 hydrocodone pain right after taking 2 advil, (ibuprofen) so will he be ok?

Yes: But one shouldn't be able to 'accidentally' take any kind of pill. If it was prescribed, it should be in it's own bottle, and if it wasn't, he should not be taking it. A single hydrocodone pill contains anywhere from 5-10 mg of hydrocodone and 325-750 mg of tylenol (acetaminophen). This could cause problems if combined with other sedative drugs, alcohol or more tylenol (acetaminophen), but not with a couple of otc ibuprofen.
