Pacerone Side Effects
Clinical studies have shown that 75 percent of people who take Pacerone will develop some type of reaction to this drug. Some of the most commonly reported Pacerone side effects include fatigue, constipation, and nausea. While many problems tend to be minor, there are serious side effects like chest pain or problems breathing that require immediate medical treatment.
An Introduction to Pacerone Side EffectsJust like any medicine, Pacerone® (amiodarone hydrochloride) can cause side effects. In fact, side effects are quite common with this medicine, occurring in about 75 percent of people in clinical trials. Fortunately, in many cases, reactions tend to be minor and either require no treatment or are treated easily by you or your healthcare provider.
If serious or intolerable side effects occur, your healthcare provider may reduce your dose or recommend you stop taking the medicine altogether. In clinical trials, up to 20 percent of people stopped taking Pacerone due to side effects.
(This article covers many, but not all, of the possible side effects with Pacerone. Your healthcare provider can discuss a more complete list with you.)
