Can I take 15 and Sevodyne together?

Why this happens

Both medicines act as central nervous system (CNS) depressants. Sevodyne (buprenorphine) is a strong opioid painkiller, and '15' (commonly referring to 15mg Phenobarbital or a similar sedative) is a barbiturate. When used together, they 'stack' their effects on the brain, leading to profound sedation and a suppressed drive to breathe.

You should not take these two medicines together unless specifically instructed and closely monitored by your doctor. If you are already taking both, do not stop suddenly, but contact your doctor immediately to discuss a safe plan. Seek emergency medical help if you experience extreme drowsiness, shallow breathing, or feel like you might faint.
