He took excedrin 4hrs ago but has been throwing up since, now has a fever, can he take an ibuprofen?

NO!: Stop all aspirin ( excedrin) and NSAIDS ( ibuprofen )- both will cause increased acid production and GI distress. Only low dose Tylenol and a clear fluid diet: NO SOLID FOODS FOR 48 HOURS Force fluids: 8-10 glasses/day: Electrolyte rich fluids- Gatorade, Powerade, Vitamin Water Protein rich fluids: broth bullion, consume. AVOID ALL CITRUS JUICES: orange, grapefruit, pineapple, cranberry etc. Avoid all aspirin, Advil, Aleve (NSAIDS). If not improving go to private physician or ER.
