What a PBS listing establishes
The PBS record establishes a subsidised product and prescribing framework. It does not guarantee that every pharmacy has stock, that every consultation is bulk-billed, or that the medicine is suitable for a particular person.
The amount paid can be lower than the maximum co-payment. Safety Net status and other rules also matter. Ask the pharmacy to price the actual prescription.
Prescribing and clinical assessment
Naltrexone is prescription-only. A clinician considers the treatment indication, current or recent opioid use, liver history, pregnancy, other medicines, and treatment goals. Starting it too soon after opioids can precipitate severe withdrawal.
Primary care may be an appropriate starting point, but same-day prescribing should never be promised: assessment, laboratory work, referral, or product availability may take additional time.
