About Welhart 50 Capsule
Welhart 50 Capsule is used to treat life-threatening arrhythmias (irregular heartbeats) such as ventricular arrhythmia. Arrhythmia is a condition in which your heart beats irregularly, too fast, or too slow.
Welhart 50 Capsule contains Mexiletine, which works by reducing the sensitivity of heart muscle cells to electrical impulses. Thus, it slows down electrical conduction in the heart muscle. Therefore, it helps restore regular heart rhythm.
In some cases, Welhart 50 Capsule may cause common side effects such as stomach pain, difficulty sleeping, indigestion, dizziness, tremors (involuntary shaking), chest discomfort or headache. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist, please consult your doctor.
If you are allergic to Mexiletine, local anaesthetics, or other medicines, please tell your doctor. If you are pregnant or breastfeeding, it is advised to inform your doctor before taking Welhart 50 Capsule . Welhart 50 Capsule is not recommended for children and adolescents below 18 years of age.
