Warning and Precautions

Serious Warnings and Precautions

  • Amiodarone Hydrochloride for Injection is intended for use only in patients with the indicated life-threatening arrhythmias because its use is accompanied by substantial toxicity.
  • Pulmonary fibrosis (permanent scarring of the lungs) can occur and can be fatal.
  • Like other antiarrhythmics, Amiodarone Hydrochloride for Injection can worsen or start an irregular heartbeat (arrhythmias).
  • Liver injury is common with amiodarone, but is usually mild, however it can be serious and even fatal in some cases.

Before using Amiodarone Hydrochloride for Injection, talk to your doctor or pharmacist if:

  • You have hepatitis, thyroid problems, or lung abnormalities
  • You are breast-feeding, pregnant or planning on becoming pregnant
  • You anticipate undergoing any surgery

Precautions when taking Amiodarone Hydrochloride for Injection

Consult your doctor if you experience these or other side effects, as the dose may have to be adjusted:

  • Amiodarone Hydrochloride for Injection may cause a worsening of the existing arrhythmia or precipitate a new arrhythmia.
  • both hyper- and hypothyroidism (too much or too little thyroid hormone released into the blood by the thyroid gland) may occur during, or soon after treatment with Amiodarone Hydrochloride for Injection.
  • one of the most serious complications is pulmonary (lung) toxicity, characterized by scarring or inflammation of the lungs. Clinical symptoms include cough, progressive shortness of breath, accompanied by weight loss and weakness.
  • Amiodarone Hydrochloride for Injection induces photosensitization in about 10% of patients. Sunscreen preparations or protective clothing may afford some protection to individual patients experiencing photosensitization. Blue-grey discolouration of exposed skin has been reported during long-term treatment. With discontinuation of therapy, the pigmentation fades slowly over a period of up to several years. The risk may be increased in patients of fair complexion or those with excessive sun exposure, and may be related to cumulative dose and duration of therapy.
  • Loss of vision or other visual disturbances such as visual halos or blurred vision.
  • Symptoms of nerve damage (peripheral neuropathy) such as pain, burning, or numbness
  • Progressive skin rash, often with blisters or lesions, which may lead to severe skin reactions that are sometimes fatal.


There have been reports of fatal “gasping syndrome” in babies less than one month old after receiving intravenous solutions containing the preservative benzyl alcohol.

Intravenous amiodarone has been found to leach out plasticizers (DEHP) from intravenous tubing which may adversely affect male reproductive tract development in the fetus, infant, and toddler if the exposure is several times higher than in adults.
