What is the most important information I should know about buprenorphine (Buprenex)?

Like other narcotic medicines, buprenorphine can slow your breathing. Death may occur if breathing becomes too weak. Using buprenorphine improperly will increase your risk of serious side effects or death. Follow all dosing instructions carefully. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

Do not use buprenorphine with other narcotic pain medications or sedatives, tranquilizers, sleeping pills, muscle relaxers, or other medicines that can make you sleepy or slow your breathing. Dangerous side effects may result.

Do not drink alcohol. Buprenorphine can increase the effects of alcohol, which could be dangerous.

Buprenorphine may be habit-forming and should be used only by the person it was prescribed for.
