WARNINGS AND PRECAUTIONS
Serious Warnings and Precautions
NU-AMIODARONE 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, NU-AMIODARONE can worsen
or start an irregular heartbeat (arrhythmias).
Liver injury is common with NU-AMIODARONE, but is
usually mild, however it can be serious and even fatal in some cases.
Before you use NU-AMIODARONE talk to your doctor if:
- you have hepatitis, thyroid problems or lung abnormalities,
you are breast feeding, pregnant or planning on becoming pregnant,
- anticipate undergoing any surgery,
- you have any allergies to this drug or its ingredients or components of the container,
you are taking any medications (see INTERACTIONS
WITH THIS MEDICATION).
Precautions when taking NU-AMIODARONE
Consult your doctor if you experience these or other side effects, as the dose may have to be adjusted:
- NU-AMIODARONE 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 NU-AMIODARONE.
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.
NU-AMIODARONE 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.

SIDE EFFECTS AND WHAT TO DO ABOUT THEM
You may experience side effects with the use of NU-
AMIODARONE.
North American experience with chronic oral amiodarone therapy suggest that amiodarone-associated adverse drug reactions are very common, having occurred in approximately 75% of patients taking 400 mg or more per day. The most serious adverse effects associated with the use of amiodarone involve your lungs, irregularities of your heart beat and hepatitis. Symptoms that suggest side effects relating to lung inflammation or scarring include: progressive shortness of breath, cough, weakness and weight loss. Symptoms that may suggest an irregularity of heart beat include: fainting, dizziness, light-headedness, weakness and chest pain.
Your doctor should monitor your blood for liver function. The following symptoms may be signs of liver problems: prolonged nausea and vomiting, abdominal pain or discolouration of the skin.
Other symptoms causing discontinuations less often have included disturbances of vision, reactions of the skin to sunlight, blue skin discoloration, hyperthyroidism and hypothyroidism.
Hypotension (low blood pressure), while seen, is uncommon (less than 1%) during amiodarone tablets therapy.
Chronic (i.e., long-term) administration of amiodarone tablets in rare instances may lead to the development of nerve damage (peripheral neuropathy) that may resolve
when amiodarone is discontinued, but this resolution has been slow and incomplete (see Precautions when taking NU-AMIODARONE).
Should you experience any of these while taking NU-AMIODARONE, consult your doctor immediately.
