Mexiletine

Drug Details

Mexiletine is an anti-arrhythmic medication used to treat certain serious irregular heartbeats, specifically ventricular arrhythmias, which occur in the heart's lower chambers. It works by blocking specific electrical signals in the heart, stabilizing the heart rhythm to maintain a regular, steady heartbeat. This action reduces the risk of complications such as blood clots, heart attacks, or strokes. It is typically taken orally three times a day, and initial treatment requires heart rhythm monitoring through an electrocardiogram (EKG) to determine the correct dosage. Although the brand name Mexitil is no longer available, mexiletine can be obtained as a cost-effective generic capsule. Common side effects include nausea, vomiting, and heartburn, so it is advised to take the medication with food or antacids for better tolerance. Always consult your healthcare provider before starting any new medication to ensure it is safe and effective for you.
