Tonocard is a prescription medication that belongs to the class of antiarrhythmic drugs. It is primarily used in the treatment and management of certain types of irregular heart rhythms, specifically ventricular arrhythmias. Ventricular arrhythmias are abnormal heart rhythms that occur in the ventricles, the lower chambers of the heart.
The active ingredient in Tonocard is mexiletine hydrochloride, which works by blocking certain electrical signals in the heart that can cause these abnormal rhythms. By inhibiting these signals, Tonocard helps to restore and maintain a regular heart rhythm.
Tonocard is typically prescribed when other treatments have failed or are not well-tolerated. It comes in the form of oral capsules and is generally taken three times a day with or after meals. The dosage and duration of treatment will vary depending on the individual's condition and response to the medication.
As with any medication, Tonocard may cause side effects, which can range from mild to severe. Common side effects may include dizziness, nausea, vomiting, changes in taste, blurred vision, and tremors. Serious side effects are less common but can include heart failure, low blood pressure, and life-threatening arrhythmias.
It is important for individuals using Tonocard to follow their doctor's instructions carefully and report any unusual or severe side effects immediately. This medication should not be stopped abruptly, as it may worsen the underlying heart rhythm issue. A healthcare professional should be consulted before starting or discontinuing Tonocard.
