Summary
Mexiletine is used to treat certain heart rhythm disorders, like ventricular arrhythmias, which are abnormal heartbeats originating in the lower chambers of the heart. It helps stabilize the heart's electrical activity, reducing the frequency and severity of these arrhythmias.
Mexiletine works by stabilizing the heart's electrical activity, which helps prevent irregular heartbeats. It belongs to a class of drugs called antiarrhythmics, which are medications that help control abnormal heart rhythms.
The usual starting dose of Mexiletine for adults is 200 mg taken two to three times a day. The maximum recommended dose is typically 1200 mg per day. It is taken orally, which means by mouth, and should be swallowed whole without crushing or chewing.
Common side effects of Mexiletine include nausea, vomiting, and dizziness. These effects are usually mild and may go away on their own. If you experience severe or persistent symptoms, it's important to talk with your doctor.
Mexiletine can cause serious heart rhythm problems, especially in people with existing heart conditions. It should not be used by people with severe liver problems or certain heart conditions without a pacemaker. Always consult your doctor about any concerns.
