I am prescribed 15 mg oxycodone every 6 hours for chronic pain. I took my morning dose at 5:15AM and will be due again at 11:15AM. I have a medical appointment at 11:00AM today. Is it OK if I take my meds around 10:45AM prior to leaving my house to make it more convenient rather than lug my prescription bottle around all afternoon? I will be home in time for my 5:15PM dose.
