Mexiletine

Uses of Mexiletine

Mexiletine is a medication utilized to manage specific heart rhythm disorders, primarily ventricular arrhythmias. It is available in 100mg and 200mg doses and falls under the class of antiarrhythmics, specifically class IB.

Ventricular arrhythmias involve irregular heartbeats that originate from the ventricles, the heart’s lower chambers. Mexiletine helps by stabilizing electrical signals within the heart, aiding in the restoration and maintenance of a normal heart rhythm.

Often prescribed when other treatments fail to control ventricular arrhythmias, Mexiletine can be used for conditions such as ventricular tachycardia, ventricular fibrillation, and certain arrhythmias linked to other cardiac issues.

By regulating heart electrical activity, Mexiletine aids in preventing potentially life-threatening arrhythmias and enhances overall heart function. It significantly reduces symptoms like palpitations, irregular heartbeat, chest discomfort, and shortness of breath.

Side Effects of Mexiletine

While Mexiletine is effective in managing heart rhythm disorders, it can cause side effects. Common side effects include nausea, vomiting, dizziness, headache, and tremors. If these side effects persist or worsen, one should consult a healthcare professional.

Dosage of Mexiletine

The typical initial dosage for Mexiletine is 200mg every 8 hours. A healthcare provider may start with a lower dose and gradually increase it based on the patient’s response and tolerance. The goal is to find the lowest effective dose that manages the heart rhythm disorder efficiently. Mexiletine is usually taken orally, with or without food. Capsules should be swallowed whole, not crushed or chewed, and taken with a glass of water. The specific dosing schedule and duration of treatment are tailored to the patient’s response to the medication.

Composition of Mexiletine

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

Precautions for Mexiletine

Certain precautions are necessary when taking Mexiletine. Patients should inform their healthcare provider about any current medical conditions, allergies, or medications being taken, as these can interact with Mexiletine. Mexiletine may affect liver function, warranting periodic monitoring. It is crucial to adhere to the prescribed dosage and not discontinue the medication without consulting a healthcare professional.
