What is the most important information I should know about this drug (Butrans)?

You should not use buprenorphine if you are allergic to it, or if you have a severe breathing disorder such as asthma, or a bowel obstruction called paralytic ileus.

Never wear more than 1 buprenorphine skin patch at a time unless your doctor has told you to.

Call your doctor at once if you have weak or shallow breathing, snoring that is new or unusual, slow heart rate, confusion, severe dizziness, seizure, or feeling like you might pass out.

Avoid letting another person handle your buprenorphine skin patches. Keep both used and unused patches out of the reach of children or pets. The amount of buprenorphine in a used skin patch could be fatal to a child or pet who accidentally sucks or chews on it. Seek emergency medical attention if this happens.

Do not stop using buprenorphine suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to avoid withdrawal symptoms when you stop using buprenorphine.
