Mexiletine

Uses of Mexiletine

Mexiletine, available in 100mg and 200mg strengths, is a medication prescribed to manage certain heart rhythm disorders, particularly ventricular arrhythmias. It belongs to the class of antiarrhythmic drugs, specifically the class IB antiarrhythmics.

Ventricular arrhythmias are irregular heartbeats originating from the ventricles, the lower chambers of the heart. Mexiletine works by stabilizing the electrical signals in the heart, helping to restore and maintain a normal heart rhythm.

Mexiletine is typically prescribed when other treatments have not been effective in controlling ventricular arrhythmias. It may be used in conditions such as ventricular tachycardia, ventricular fibrillation, and certain types of arrhythmias associated with other cardiac conditions.

By regulating the heart’s electrical activity, Mexiletine helps to prevent potentially life-threatening arrhythmias and improve the overall functioning of the heart. It can significantly reduce symptoms such as palpitations or irregular heartbeat, chest discomfort, and shortness of breath.

Mexiletine is available in two strengths: 100mg and 200mg. Each tablet contains the active ingredient Mexiletine hydrochloride, along with other inactive ingredients.

Precautions of Mexiletine

There are certain precautions to keep in mind when taking Mexiletine. It is important to inform the healthcare provider about any existing medical conditions, allergies, or medications being taken, as they may interact with Mexiletine. Additionally, Mexiletine may affect the liver and may require periodic monitoring of liver function. It is crucial to follow the prescribed dosage and not discontinue the medication without consulting a healthcare professional.

Dosage of Mexiletine

For most patients, the initial recommended dosage of Mexiletine is 200mg every 8 hours. However, the healthcare provider may start with a lower dose and gradually increase it as necessary, based on the patient’s response and tolerance to the medication. The goal is to find the lowest effective dose that effectively manages the heart rhythm disorder. It is typically taken orally, with or without food. Mexiletine capsules should be swallowed whole, without crushing or chewing, and washed down with a glass of water. The dosing schedule and duration of treatment will be based on the patient’s response to the medication.
