Acute non-ST segment elevation myocardial infarction following intravenous injection of sublingual Suboxone.

Non-ST segment elevation myocardial infarction (NSTEMI) is a relatively unknown complication of injecting sublingual Suboxone (buprenorphine/naloxone). Buprenorphine/naloxone should be taken as a sublingual tablet or a buccal film and not injected, so its effects from this mode of administration are not well known. While the differential diagnosis for chest pain is very broad, many practitioners do not associate chest pain with the use of buprenorphine/naloxone. We recommend considering serial electrocardiograms (ECGs) and high-sensitivity troponins for a patient who presents with chest pain after buprenorphine/naloxone use.
