Ahmad is a 22 year-old male who has been taking oxycodone and morphine for over 10 years for his chronic back pain. He decided to stop oxycodone and morphine. He states, ‘I would like to use only ibuprofen from now onwards’. However, first he would like to take buprenorphine to taper off his dependence on oxycodone and morphine. His physician started him on buprenorphine-naloxone 8/2 mg. Within a few hours, Ahmad developed nausea, vomiting, diarrhea, muscleaches, rhinorrhea, sweating and insomnia. In the physical examination, he was found to have pupillary dilation, piloerection and yawing. What is the next best step in management?
