I took 2 excedrin and 2 ibuprofen together. and now im throwing up is there anything to worry about?

Something you ate, bacterial infection, food poisoning, allergic response, virus, and so many other things, including the reason that you took so many nSaids at one time. Call your GP. If you don't have one, Urgent Care is the second best alternative.

You did not overdose with these medications, though these could have irritated the stomach to induce vomiting though vomiting may be unrelated to medications. Drink enough water so that your urine is mostly colorless, to ensure proper hydration.
