I just took 4 200 miligram ibuprofen on accident can I overdose on this amount?

If they were all at once, shouldn't be a problem. Assuming they were trusted brands, the worst that could happen would be a little dizziness, and tired numb feelings. Sit down and watch one of your favorite movies, or read a book. Don't do anything that requires great speed. Check the back of the container, and see how long it lasts, and do this until then.
