Doctors usually prescribe this medicine when other pain relievers fail to control your discomfort or when those standard medicines cause side effects you cannot tolerate.

Important Things to Watch While Taking This Medicine
Managing severe pain safely requires careful attention to how your body responds. Keep these practical guidelines in mind while receiving butorphanol:
- Monitor your pain levels: Let your doctor know if your pain does not improve, if it gets worse, or if you feel a new kind of pain.
- Understand tolerance: If you use this medicine for a long time, your body may get used to it. You might find that the usual dose stops working as well. This is called drug tolerance.
Tolerance is not the same as addiction. Addiction involves an overwhelming, uncontrollable urge to use a substance for emotional reasons or pleasure rather than medical needs. If you take this medicine for pain, you have a valid medical reason.
- Do not stop suddenly: Never stop taking this medicine abruptly without talking to your doctor first. Stopping suddenly can trigger uncomfortable withdrawal symptoms. Your doctor will gradually lower your dose when it is time to stop.
- Dizziness and drowsiness: This medicine can make you feel sleepy or dizzy. Avoid driving, operating heavy machinery, or doing dangerous tasks until you know how the medicine affects you. If you are an older adult, take care when standing up from a sitting position to prevent falls.
- Avoid alcohol: Do not drink alcohol while taking this medicine. Alcohol can worsen side effects like severe drowsiness and dangerous breathing slowdowns.
- Learn about Naloxone: Naloxone is an emergency medicine that can reverse an opioid overdose and save a life. Ask your doctor if you or your family members should have naloxone on hand, and learn how to recognize signs of overdose such as slow breathing or severe sleepiness.
- Watch for constipation: Opioids often cause constipation. Drink plenty of water and eat fiber-rich foods. If you do not have a bowel movement for three days, talk to your doctor.
- Manage dry mouth: If your mouth feels dry, try chewing sugar-free gum or sipping water throughout the day.
