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.
Take your dose with a full glass of water. If you're taking regular prescribed doses, never take a double dose. If you miss a dose and it's almost time for your next dose, skip the one you forgot. Do not lie down for at least 10 minutes after taking ibuprofen. If you're taking ibuprofen for headache, try to take it as soon as the headache begins when it will be more effective. This is a balancing act, because you also want to take as small an ibuprofen dosage as possible.
