My spouse has been under the care of a Pain Management Specialist for several years. They started her on Norco-2 tabs every 4-6 hours; Then switched her to 20mg Oxycontin-1 tab every 12 hours; Then to 30mg Oxycodone-1.5 tabs every 4-6 hours as needed; Now they changed her to 30mg MS Contin and she claims she's supposed to take 2 pills at a time every 6 hours, but hasn't left her prescription bottle out anywhere that I could see it to confirm that and I'm concerned she might be over medicating!
