Regulatory and Compliance Guidance
When AMIODARONE HYDROCHLORIDE appears on a claimant's medication list, claims professionals should assess whether the prescribing is appropriate for the compensable injury, whether the duration is within guidelines, and whether there are interactions with other medications on the claim.
Australia TGA / PBS / State Schemes
Classified as S4 under the Therapeutic Goods Administration (TGA).
WorkSafe Victoria Drugs of Dependence Guidelines require monitoring for all S8 opioids. WorkCover QLD Pain Intervention Guidelines recommend multimodal pain management with opioids as a last resort.
United Kingdom NICE / MHRA / FPM
NICE NG193 (Chronic Pain) recommends against initiating opioids for chronic primary pain. The Faculty of Pain Medicine (FPM) Opioids Aware resource recommends structured opioid prescribing with regular review, dose limits, and documented tapering plans.
For personal injury claims in the UK, opioid prescribing duration and dose should be reviewed against NICE and FPM guidelines. Costs may be recoverable as a disbursement in high-value PI claims.
United States FDA / CDC / State WC
FDA approved for use in the United States.
FDA Boxed Warning: WARNING: PULMONARY, HEPATIC and CARDIAC TOXICITY Pacerone is intended for use only in patients with the indicated life-threatening arrhythmias because its use is accompanied by substantial toxicity [see Indications and Usage (1) ] . Pacerone can cause pulmonary toxicity (hypersensitivity pneumonitis or interstitial/alveolar pneumonitis) that has resulted in clinically manifest disease at rates as high as 17% in some series of patients. Pulmonary toxicity has been fatal about 10% of the time . Obtain a baseline chest X-ray and pulmonary-function tests, including diffusion capacity, when Pacerone therapy is initiated. Repeat history, physical exam, and chest X-ray every 3 to 6 months [see Warnings and Precautions 5.2) ] . Pacerone can cause hepatoxicity, which can be fatal. Obtain baseline and periodic liver transaminases and discontinue or reduce dose if the increase exceeds three times normal, or doubles in a patient with an elevated baseline. Discontinue Pacerone if the patient experiences signs or symptoms of clinical liver injury [see Warnings and Precautions (5.3) ] . Pacerone can exacerbate arrhythmias. Initiate amiodarone hydrochloride in a clinical setting where continuous electrocardiograms and cardiac resuscitation are available [see Warnings and Precautions (5.4) ] . WARNING: PULMONARY, HEPATIC, and CARDIAC TOXICITY See full prescribing information for complete boxed warning. Reserve Pacerone for patients with the indicated life-threatening arrhythmias because its use is accompanied by substantial toxicity, some also life-threatening. Utilize alternative agents first. ( 1 ) Pacerone' s life-threatening toxicities include pulmonary ( 5.2 ), hepatic ( 5.3 ), and proarrhythmic ( 5.4 ). Initiate under hospital or specialist supervision. ( 5 )
The CDC Clinical Practice Guideline for Prescribing Opioids (2022) recommends non-opioid therapies as first-line treatment for pain. When opioids are prescribed, the lowest effective dose should be used for the shortest duration needed.
For workers compensation claims, many states require prior authorization for opioids beyond initial acute prescribing. State drug formularies (e.g. California MTUS, Texas, New York) may restrict or require step therapy before opioid approval.
New Zealand ACC / BPAC NZ / Medsafe
BPAC NZ recommends reassessing opioid therapy at regular intervals and limiting duration. The NZ Opioid Prescribing B-QuiCK Guide provides structured prescribing and tapering protocols.
ACC (Accident Compensation Corporation) covers treatment-related medications for accepted claims. Opioid prescribing beyond guidelines may require ACC clinical review and approval.
