I took an oxycodone tablet today (10-325) and while working up a good sweat in the garage I suddenly became extremely dizzy. I take a minimal amount of this medication to relieve severe pain. I allow myself only one a day. I was shocked at how quickly and seriously dizzy I became and was wondering if it was related to the severe perspiration I was experiencing at the time. No chest pain ot anything. Once I sat down on a cool room I immediately returned to normal. I would appreciate any feedback as the experience really shook me up. Thank you.
