Precautions when taking Amiodarone Hydrochloride Injection:
Consult your doctor if you experience these or other side effects, as the dose may have to be adjusted:
- Amiodarone Hydrochloride Injection may cause a worsening of the existing arrhythmias 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 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 Injection induces photosensitization in about 10% of patients. Sunscreen preparations or protective clothing may afford some protection to individual patients experiencing photosensitization. Blue-grey discoloration 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.
