When to seek emergency help: Breathing becomes slow or shallow, extreme drowsiness or inability to wake, blue lips or fingernails, severe confusion, or loss of consciousness. Keep naloxone (Narcan) accessible if prescribed opioids. Never mix with alcohol.
No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. Say: "I take Diphenhydramine and Buprenorphine — is that OK?"
These medications are safe to take together at standard doses. Continue taking as prescribed and keep your pharmacist informed of your complete medication list.
