How Long Does It Take for Ibuprofen to Kick in?
In general, it often takes around 30 minutes for ibuprofen to kick in. Nevertheless, this can vary from person to person for various reasons. When the drug starts to work, you will often begin to notice a drop in fever or pain. The anti-inflammatory effects often take longer, typically one week or even more. The levels of ibuprofen in the blood can reach the peak after one or two hours. Nevertheless, the body might clear it quickly. That’s why you might need to take one dose every few hours, depending on the treated condition. The timing seems to be similar in adults and children. Kids and younger children might clear ibuprofen from the body more quickly than adults.[3]
