Key points
- Stop-smoking medicines include varenicline and bupropion; behavioural support can improve the chance of quitting.
- Naltrexone, acamprosate and disulfiram have different roles in alcohol dependence and are not interchangeable.
- Alcohol or opioid withdrawal can require supervised care; suddenly stopping some substances without medical support can be dangerous.

How the medicine groups differ
Stop-smoking medicines work in different ways to reduce nicotine cravings or withdrawal. Alcohol-dependence medicines may reduce reward, support abstinence or cause an unpleasant reaction with alcohol. Some medicines used for alcohol dependence also have a role in opioid dependence, but starting them at the wrong time can precipitate withdrawal.
What these medicines are used for
This category covers treatment for tobacco dependence, alcohol dependence and opioid dependence. Medication is usually one part of a broader plan that may include counselling, peer support and follow-up.
Important safety checks
A clinician may need to review current substance use, withdrawal history, mental health, pregnancy, liver or kidney function and possible medicine interactions. Do not use someone else’s medicine or combine treatment with alcohol, opioids or sedatives unless the prescriber has confirmed that it is safe.
When to seek urgent care
Get urgent help for severe confusion, hallucinations, seizures, breathing difficulty, loss of consciousness or thoughts of self-harm. Suspected overdose or severe alcohol withdrawal is a medical emergency.
