I usually take 15mg of percocet every 4 hours. I am prescribed 10 mg but do the 15 . Its per my pain management doctor. Lately my anxiety is through the roof so I asked my family doctor for klonopin. She prescribed .5 mg twice daily. I took 15mg of percocet an hour ago, i just took half of my klonopin, so . 25 mg. Is that a safe combo as i am not opiate nieve?
