BUPRENORPHINE/ NALOXONE

(Suboxone)

Standard Prescription

Mechanism of Action

Buprenorphine is a long acting partial opioid agonist.
Naloxone is an opioid reversal agent.

Naloxone is in the product to deter crushing and injecting the buprenorphine. When taken via the sublingual route, naloxone is not active (not absorbed). However, when injected, naloxone is active and will reverse the effects of buprenorphine.

Buprenorphine 2 mg/naloxone 0.5 mg sublingual tablet

Buprenorphine 8mg/naloxone 2mg sublingual tablet

Comments

Tablets should only be administered via the sublingual (SL) route, as absorption of buprenorphine is significantly decreased if swallowed (taken orally (PO)).

The tablets can take up to 15 minutes to dissolve. Instruct patient to avoid swallowing, talking, eating, drinking, and smoking during this time.

COWS score should be performed to assess withdrawal symptoms.

Adverse effects are similar to other opioids: e.g., sedation, dizziness, nausea, vomiting, and constipation.  Risk of respiratory depression is lower than with other opioids but still possible.

Should only be initiated by prescribers with experience in substance use management.
