A common component of household medicine cabinets, <\/span>Imodium<\/span><\/a> (<\/span>loperamide<\/span>), is an <\/span>over-the-counter<\/span> (<\/span>OTC<\/span>) <\/span>antidiarrheal<\/span> prescribed to <\/span>treat diarrhea<\/span>, <\/span>dysentery<\/span>, <\/span>traveler’s diarrhea<\/span>, <\/span>chronic diarrhea<\/span>, or high <\/span>ileostomy<\/span> output. <\/span>Imodium<\/span> carries a warning from the Food and Drug Administration (<\/span>FDA<\/span>) regarding an association between high doses and cases of sudden cardiac death. While uncommon, this risk of toxicity could be potentiated by any of the number of other drugs that <\/span>prolong the QT interval<\/span><\/a>, a measure of the heart’s electrical conduction. One should avoid concurrent use of medications that increase <\/span>Imodium<\/span> concentrations, such as certain antivirals, antifungals, and cholesterol-lowering drugs. To find out if a current medication interacts with <\/span>Imodium<\/span>, talk to a <\/span>healthcare provider<\/span> prior to taking <\/span>Imodium<\/span>. Their <\/span>medical advice<\/span> will be imperative in determining whether one should take the <\/span>non-prescription<\/span> antidiarrheal<\/span>.<\/span><\/p>\n

Imodium<\/span> drug interactions<\/span><\/h2>\n

The two main categories of <\/span>drug interactions<\/span> with <\/span>Imodium<\/span> relate to QT prolongation, and ones that pertain to cytochrome p450 enzyme metabolism. There are numerous medications within each class, so while learning some of the more common examples is helpful, always double-check with a doctor or pharmacist.<\/span><\/p>\n

QT-prolonging agents<\/span><\/h3>\n

The QT interval is the timeframe in the electrical cycle of a heartbeat when the ventricular pumping chambers beat and then reset. If this timeframe is prolonged, it may trigger a dangerous <\/span>heart rhythm<\/span> called <\/span>Torsades de Pointes<\/span>, which is a form of ventricular tachycardia that can lead to <\/span>sudden cardiac death<\/span><\/a>. One can be born with prolonged QT syndrome, but more commonly, it is acquired by an adverse drug effect. Overdoses of <\/span>Imodium<\/span> have been linked to this condition.<\/span><\/p>\n

Taking multiple medications that prolong the QT interval can compound the risk. Accordingly, this must be done carefully or avoided. Seek medical care immediately if symptoms of <\/span>heart racing<\/span><\/a> or fainting occur while taking <\/span>Imodium<\/span>. Check with a doctor before taking <\/span>Imodium<\/span>. Decisions on limiting the danger when taking <\/span>Imodium<\/span> or other QT-prolonging agents are best discussed with the prescribing <\/span>healthcare professional<\/span>. Examples of QT-prolonging agents  include the following drug categories and members:<\/span><\/p>\n
