6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

At the usual maintenance dose (400 mg/day) and above, amiodarone hydrochloride causes adverse reactions in about three-fourths of all patients, resulting in discontinuation in 7 to 18%.

In surveys of almost 5,000 patients treated in open U.S.

studies and in published reports of treatment with amiodarone hydrochloride, the adverse reactions most frequently requiring discontinuation of amiodarone hydrochloride included pulmonary infiltrates or fibrosis, paroxysmal ventricular tachycardia, congestive heart failure, and elevation of liver enzymes.

Other symptoms causing discontinuations less often included visual disturbances, photosensitivity, blue skin discoloration, hyperthyroidism, and hypothyroidism.

The following side-effect rates are based on a retrospective study of 241 patients treated for 2 to 1,515 days (mean 441.3 days): Thyroid Common: Hypothyroidism, hyperthyroidism.

Cardiovascular Common: Congestive heart failure, cardiac arrhythmias, SA node dysfunction.

Gastrointestinal Very common: Nausea, vomiting.

Common: Constipation, anorexia, abdominal pain.

Dermatologic Common: Solar dermatitis/photosensitivity.

Neurologic Common: Malaise and fatigue, tremor/abnormal involuntary movements, lack of coordination, abnormal gait/ataxia, dizziness, paresthesias, decreased libido, insomnia, headache, sleep disturbances.

Ophthalmic Common: Visual disturbances.

Hepatic Common: Abnormal liver-function tests, nonspecific hepatic disorders.

Respiratory Common: Pulmonary inflammation or fibrosis.

Other Common: Flushing, abnormal taste and smell, edema, abnormal salivation, coagulation abnormalities.

Uncommon: Blue skin discoloration, rash, spontaneous ecchymosis, alopecia, hypotension, and cardiac conduction abnormalities.

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of amiodarone hydrochloride.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Hematologic : hemolytic anemia, aplastic anemia, pancytopenia, neutropenia, thrombocytopenia, agranulocytosis, granuloma.

Immune : anaphylactic/anaphylactoid reaction (including shock), angioedema.

Neurologic : pseudotumor cerebri, parkinsonian symptoms such as akinesia and bradykinesia (sometimes reversible with discontinuation of therapy), demyelinating polyneuropathy.

Psychiatric : hallucination, confusional state, disorientation, delirium.

Cardiac : hypotension (sometimes fatal), sinus arrest.

Respiratory : eosinophilic pneumonia, acute respiratory distress syndrome in the post-operative setting, bronchospasm, bronchiolitis obliterans organizing pneumonia, pulmonary alveolar hemorrhage, pleural effusion, pleuritis.

Gastrointestinal : pancreatitis, acute pancreatitis.

Hepatic : hepatitis, cholestatic hepatitis, cirrhosis.

Skin and Subcutaneous Tissue Disorders : urticaria, toxic epidermal necrolysis (sometimes fatal), erythema multiforme, Stevens-Johnson syndrome, exfoliative dermatitis, bullous dermatitis, drug rash with eosinophilia and systemic symptoms (DRESS), eczema, pruritus, skin cancer, lupus-like syndrome.

Musculoskeletal : myopathy, muscle weakness, rhabdomyolysis.

Renal : renal impairment, renal insufficiency, acute renal failure.

Reproductive : epididymitis, impotence.

Body as a whole : fever, dry mouth.

Endocrine and metabolic : thyroid nodules/ thyroid cancer, syndrome of inappropriate antidiuretic hormone secretion (SIADH).
