Try an antacid, liquid or tablets and a small bland snack, like half a banana or a few crackers or a piece of toast.
Ibuprofen should not be taken on an empty stomach or if you have nausea, vomiting, diarrhea or abdominal pain or with alcohol. If your stomach does not feel better soon, see a doc. If you have black or bloody stools, dizziness, weakness, or increasing pain, go to an ER.
