can vivitrol cause a false positive
Answered by The Community. Making the world better, one answer at a time. Yes Naltrexone has been known to test positive for opiates in almost all at-home drug screens. I was baffled when I tested my daughter, until I called her doctor and confirmed that Naltrexone can indeed cause a false-positive.uboxone can test positive for opiates, as it contains buprenorphine, a mixed agonist-antagonist opiate. Suboxone also contains naloxone, an opiate antag onist.
