01 · How it works
Origins & Mechanism
Suboxone combines buprenorphine, a high-affinity partial mu-opioid agonist, with naloxone to reduce opioid cravings and discourage injection misuse.

03 · Long-term consequences
Precipitated withdrawal hazard
If taken while full opioids such as fentanyl or heroin are active, buprenorphine can displace them from receptors and trigger sudden severe withdrawal.
Medical emergency
Identifying an emergency
Coma, pinpoint pupils, or shallow breathing—especially when mixed with sedatives—require 911 and naloxone.
Note: Multiple naloxone doses may be needed
