How long insulin takes to lower blood sugar depends on the type: rapid-acting starts in 10-15 mins (peaks 1-2 hrs), short-acting in 30 mins (peaks 2-3 hrs), intermediate-acting in 2-4 hrs (peaks 4-12 hrs), and long-acting in a few hours (lasts 12-24+ hrs). Rapid and short-acting are for meals, while intermediate and long-acting provide background coverage, with timings varying by brand and individual.
