Answer by Ninakhan. Confidence votes 883. It usually takes 20 minutes to a half hour for medicine to work, but some medicine takes more time then others. Tramadol, for example, can take 50-55 minutes to really get rolling in the blood stream, but will usually last six hours.peaking from experience: usually it would take me about 5 days to a week after my last pain Med.
