The most common side effect of Buprenex (buprenorphine) is sedation. Other side effects include nausea, dizziness, back pain, warm or tingly feelings, constipation, weakness, anxiety, insomnia, runny nose, sweating, headache, vomiting, low blood pressure, and slowed breathing. Some of Buprenex's side effects may be serious and require immediate medical attention; these include breathing that is very slow or shallow, lightheadedness or fainting, unusual thoughts or behavior, confusion, and nausea with low fever, stomach pain, diminished appetite, dark urine, clay-colored stools, and jaundice.
As with other narcotics there is also the possible side effect of drug dependence and abuse. Caution should be used when prescribing Buprenex for someone with a history of drug abuse or addiction. If you have an allergic reaction (facial swelling, hives, breathing difficulty, and rash) seek emergency care.
