how long should you wait to take ibuprofen
Depending on what painkiller, and why. If it's another NSAID, you should wait around 4 to 6 hours unless the dose of ibuprofen was low e.g. 200 mg. As for ibuprofen, if the pain didn't lessen after taking a dose of ibuprofen, if no stomach ache I would prefer one taking more ibuprofen up to maximum of 800 mg in total.
