What Are the Most Common Amiodarone Side Effects?

Amiodarone is a prescription drug often used to treat irregular heartbeats when other drugs are unsuccessful. Quite a few side effects of amiodarone are not necessarily dangerous, such as constipation, flushing, or a lack of appetite. Sometimes, however, amiodarone side effects are dangerous, such as excessive sweating or unusual swelling. Other side effects include involuntary movements and sensitivity to temperature. Finally, overdose can be indicated by side effects such as fainting or nausea.

The physical side effects of constipation and headache afflict patients on this medication. In addition, physical amiodarone side effects include an unusual lack of appetite, sometimes for longer than a day. Furthermore, the flushing of a patient’s skin or dry eyes are often experienced. While all of these side effects can be dangerous if they are prolonged or severe, they are not necessarily immediately dangerous.

A few of the possible amiodarone side effects can be harder to detect. Sometimes, a person who is taking the drug has a change — positive or negative — in the amount of saliva that his or her body produces. Other times, the senses of smell and taste can be affected. In addition, some patients report a decrease in their sex drive or insomnia. If these side effects are severe or concerning, it is generally a good idea to communicate with a qualified professional.

Some of the possible amiodarone side effects are always dangerous, even if they do not persist. It is generally recommended that if any of these side effects occur while a person is taking amiodarone he or she should immediately contact a medical professional for advice. One of the possible physical side effects is experiencing uncontrollable body movements, such as shaking or having coordination problems while performing activities such as walking. In addition, side effects such as excessive sweating and sensitivity to temperature can indicate a reaction to this medication. Finally, unusual tingling or swelling around numerous areas of the body can indicate a negative reaction.

A few of the side effects caused by this drug can mean that an overdose has taken place. Fainting, or even mild lightheadedness, for instance, can be a dangerous sign. If a person taking this prescription medication feels nauseous, this usually indicates an overdose as well. A slow heartbeat or blurry vision can also indicate an overdose.
