how quickly does ibuprofen take effect
According to Ibuprofen Drug Level, Serum therapeutic ibuprofen serum levels are 10 - 50 Âµgr/mL. This is how fast an appreciable serum level after oral intake of ibuprofen is reached: So those levels would be reached after 15 to 40 minutes of one taking ibuprofen by mouth, faster if combined with an antacid e.g. magnesium oxide, Tums, or whatever.
