Mexiletine slows rapid heartbeat & stabilizes irregular heartbeats
(arrhythmias). It prevents recurrence of ventricular arrhythmias, such
as premature heartbeats. It can prevent sudden death. Mexiletine
belongs to the same famils of drugs as lidocane (Xylocaine).
Mexiletine has little risk of organ toxicity
but has a high risk of noncardiac adverse effects. However, these
adverse effects often cause people to stop taking mexiletine. Lower
doses can reduce unwanted effects. People with decreased
liver function should take a lower dose.
At times mexiletine actually worsens some types of arrhythmias. Use of
mexiletine with procainamide (Pronestyl) is of little or no value.
