Butorphanol nasal spray may cause serious or life-threatening breathing problems, especially during the first 24 to 72 hours of your treatment and any time your dose is increased. Your doctor will monitor you carefully during your treatment. Tell your doctor if you have or have ever had slowed breathing or asthma. Your doctor will probably tell you not to use butorphanol nasal spray. Also tell your doctor if you have or have ever had lung disease such as chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways), a head injury or any condition that increases the amount of pressure in your brain. The risk that you will develop breathing problems may be higher if you are an older adult or are weak or malnourished due to disease. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: slowed breathing, long pauses between breaths, or shortness of breath.
Taking certain other medications with butorphanol nasal spray may increase the risk of serious or life-threatening breathing problems. Tell your doctor and pharmacist if you are taking or plan to take any of the following medications: certain antifungal medications including itraconazole (Onmel, Sporanox), ketoconazole (Nizoral), and voriconazole (Vfend); carbamazepine (Carbatrol, Epitol, Tegretol, Teril); medications for anxiety, mental illness or nausea; benzodiazepines such as alprazolam (Xanax), chlordiazepoxide (Librium), clonazepam (Klonopin), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), oxazepam, temazepam (Restoril), and triazolam (Halcion); clarithromycin (Biaxin, in PrevPac)muscle relaxants; erythromycin (Erytab, Erythrocin); certain medications for human immunodeficiency virus (HIV) including indinavir (Crixivan), nelfinavir (Viracept), and ritonavir (Norvir, in Kaletra); other narcotic pain medications; phenytoin (Dilantin, Phenytek); rifabutin (Mycobutin); rifampin (Rifadin, Rimactane, in Rifamate); sedatives; sleeping pills; or tranquilizers. Your doctor may need to change the doses of your medication and will monitor you carefully.
Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with butorphanol nasal spray also increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol or use street drugs during your treatment.
Butorphanol nasal spray may be habit-forming. Do not use more of it, use it more often, or use it in a different way than directed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse butorphanol nasal spray if you have or have ever had any of these conditions.
Tell your doctor if you are pregnant or plan to become pregnant. If you use butorphanol nasal spray regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth. Tell your baby's doctor right away if your baby experiences any of the following symptoms: irritability, hyperactivity, abnormal sleep, high-pitched cry, uncontrollable shaking of a part of the body, vomiting, diarrhea, or failure to gain weight.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with butorphanol nasal spray and each time you fill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions.

Why is this medication prescribed?
Butorphanol nasal spray is used to relieve moderate to severe pain. Butorphanol is in a class of medications called opioid agonist-antagonists. It works by changing the way the body senses pain.
How should this medicine be used?
Butorphanol nasal spray comes as a solution (liquid) to spray in the nose. It is usually used as needed for pain but not more often than once every 3 to 4 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
Butorphanol nasal spray should relieve your pain soon after you use it. If you are using a low starting dose of butorphanol nasal spray, your doctor may tell you that you may use a second dose if you still have pain 60 to 90 minutes after your first dose. Do not use this second dose unless your doctor tells you that you may. Call your doctor if you still have pain after using butorphanol nasal spray as prescribed. Also call your doctor if you have used butorphanol nasal spray for some time and find that it no longer works as well as it did at the beginning of your treatment.
Do not stop using butorphanol nasal spray without talking to your doctor. If you suddenly stop using butorphanol nasal spray, you may experience withdrawal symptoms such as nervousness, agitation, shakiness, diarrhea, chills, sweats, difficulty falling asleep or staying asleep, loss of coordination,confusion, or hallucinations (seeing things or hearing voices that do not exist). Your doctor will probably decrease your dose gradually.
