Alternating between ibuprofen and acetaminophen every 2 hours because you have to wait 4 hours for each of them to take a second dose of the same thing. So instead you take a dose of Acetaminophen now, then Ibuprofen in 2 hours and back to Acetaminophen 2 hours later as needed.
Give every six to eight hours as needed. Don't give ibuprofen to babies under 6 months without calling your doctor first. Always use the measuring device (dropper or measuring cup) that comes with the medication or you could risk overdosing. Never use droppers from different medications or spoons from the kitchen.
