I took 1 10-325 mg of Percocet and one 100 mg of Nucynta. Was told it was okay to do for breakthrough pain. I have Ankylosing Spondylitis. Have been on Fentanyl, Percocet, and Lortab. Body is used to these meds (unfortunately). I haven t been loopy for many years for these med. But I am feeling really really dizzy and loopy right now pulse is 73 bmp. I am afraid to fall asleep because I don t want my heart to stop. What is your opinion?

Summarized question: What causes dizziness while on medication for Ankylosing spondylitis?
