Concomitant use of butorphanol with Tramadol can potentiate the effects of butorphanol on respiratory depression, CNS depression (e.g., dizziness, impaired mental function), and sedation. Tramadol is eliminated from the body anywhere from 15-30 hours. If you must take Tramadol with butorphanol, you'll need to reduce the Tramadol dose and use the longest dosing frequency of butorphanol.
Thank you for your comment. I however am not taking the tramadol any longer. It was the transition from one to the other i was worried about. Going into withdrawals because of the way stadol ns is formulated and how long it would last. Its hard to get good pain relief and be in withdrawals at the same time.
