Children and infants can usually take ibuprofen every six to eight hours but should not have more than four doses in 24 hours unless directed by a doctor. If you are unsure about how much ibuprofen to give a child, consult a doctor who will determine the dosage based on the childâs weight.
Can you safely take 800 mg Ibuprofen every 4 hours? Yes you can take 800mg safely - as long as you aren't taking any  other pain medications. And I believe it should be every 6-8hr for  that amount of ibuprofin.    â¦ You cannot MIX ibuprofin & Tylenol.
