Can you take oxycodone and Norflex together or in the same day?

I suggest you contact your Dr.´s office and speak to him/her directly, as the potential interaction is the following, and I believe only a medical professional can answer this question:

Major meaning:

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.

Using narcotic pain or cough medications together with other medications that also cause central nervous system depression can lead to serious side effects including profound sedation, respiratory distress, coma, and even death. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Do not drink alcohol or self-medicate with these medications without your doctor's approval, and do not exceed the doses or frequency and duration of use prescribed by your doctor. Also, because these medications may cause dizziness, drowsiness, difficulty concentrating, and impairment in judgment, reaction speed and motor coordination, you should avoid driving or operating hazardous machinery until you know how they affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
