What is the dosage for butorphanol injection?
The initial dose for adults is based on the setting in which it is used, as well as whether it is delivered intramuscularly, intravenously, or through nasal spray. Most initial intravenous doses for pain range between 0.5 to 2 mg, which may be repeated every 3 to 4 hours as needed.
Which drugs or supplements interact with butorphanol injection?
Alvimopan (Entereg) should not be combined with butorphanol because it increases levels of butorphanol.
Butorphanol should not be taken with any of the monoamine oxidase inhibitor (MAOI) class of antidepressants, for example, isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), selegiline (Eldepryl), and procarbazine (Matulane) or other drugs that inhibit monoamine oxidase, for example, linezolid (Zyvox). Such combinations may lead to confusion, high blood pressure, tremor, hyperactivity, coma, and death. Butorphanol should not be administered within 14 days of stopping an MAOI.
