Description

Product Description

Ismo 20 Tablet is a prescription medicine containing Isosorbide Mononitrate (20mg), which belongs to the class of nitrate medicines. It works by relaxing and widening blood vessels, allowing blood to flow more easily to the heart. This helps prevent and reduce episodes of chest pain (angina) in patients with heart disease.

The tablet is not meant to provide instant relief during an acute angina attack but is used as a long-term preventive treatment. It should be taken regularly as prescribed by your doctor, usually on an empty stomach.

Uses

How to Use

Take the medicine exactly as prescribed by your doctor. Swallow the tablet whole with a glass of water, preferably on an empty stomach. Do not crush or chew the tablet. Follow the dosing schedule regularly for best results.

How It Works
