What is butorphanol? What is butorphanol used for?
Butorphanol is a synthetic opioid narcotic pain reliever. It prevents pain in a similar way as morphine (MS Contin), hydrocodone (Zohydro), oxycodone (Oxycontin), and other opioids. Like other opioids, it stimulates receptors in the brain to increase the threshold to pain (the amount of stimulation it takes to feel pain) and reduce the perception of pain (the perceived importance of the pain). The FDA approved butorphanol in August 1978.

What are the side effects of butorphanol?
The most frequent adverse reactions include drowsiness, dizziness, nausea, vomiting, and nasal congestion and insomnia with the nasal preparation. Patients may also experience palpitations, flushing, anxiety, confusion, euphoria, headache, nervousness, tingling sensation in limbs, cold/clammy skin, sweating, itchiness, anorexia, constipation, stomach pain, dry mouth, tremor, weakness, blurred vision, ringing in ears, and difficulty breathing. Butorphanol is habit forming. Mental and physical dependence can occur when used long-term.
What is the dosage for butorphanol?
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?
Combining butorphanol with other agents that cause depression of the central nervous system may lead to increased sedation and confusion.
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.
Is butorphanol safe to take if I'm pregnant or breastfeeding?
Butorphanol is excreted in breast milk. The amount that the infant may receive is very low and insignificant.

What preparations of butorphanol are available?
Solution with or without preservatives: 1 or 2 mg/mL in 1, 2, 10 mL; Nasal solution: 10 mg/ mL in 2.5 mL bottle.
How should I keep butorphanol stored?
Butorphanol solution should be stored at room temperature, between 15 C to 30 C (59 F to 86 F) and protected from light. Nasal spray should be stored at room temperature between 20 C to 25 C (68 F to 77 F).

Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.
Muscle Pain (Myofascial Pain Syndrome)
Muscle pain (myofascial pain syndrome) is muscle pain in the body's soft tissues due to injury or strain. Symptoms include muscle pain with tender points and fatigue. Treatment usually involves physical therapy, massage therapy, or trigger point injection.
Neuropathic pain is a chronic condition that leads to ongoing pain symptoms. Patients can be predisposed to developing neuropathic pain who have conditions such as diabetes, cancer, stroke, HIV, vitamin deficiencies, shingles, and multiple sclerosis. Patient history and nerve testing are used to diagnose neuropathic pain. Antidepressants, antiseizure medications, and other types of medications are used to treat neuropathic pain. Many people with neuropathic pain are able to attain some level of relief.
Pain Relief Options for Childbirth
Women experience and tolerate pain differently. For some pregnant women, focused breathing is all they need to get through labor and childbirth; but for others, numbing of the pain is desired. There are a number of different medications a woman can take during labor and childbirth. It is important for you to learn what pain relief options are available. Please discuss the options with your health care professional well before your "birth day" so that when you are in labor you understand the choices.
Pain Management: Neuropathic Pain
Neuropathic pain is chronic pain resulting from injury to the nervous system. The injury can be to the central nervous system (brain and spinal cord) or the peripheral nervous system (nerves outside the brain and spinal cord).
