Mexitil (Mexiletine) is used to treat certain types of serious irregular heartbeat (such as persistent ventricular tachycardia). It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Mexiletine is known as an anti-arrhythmic drug. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat. Treating an irregular heartbeat can decrease the risk for blood clots, and this effect can reduce your risk of heart attack or stroke. Take this medication by mouth with a full glass of water and food or an antacid. Taking this medication with food or an antacid helps to decrease certain side effects (nausea, heartburn). Ask your pharmacist if you have questions about which antacids to use with this medication.
