How to use

Take Isosorbide Mononitrate exactly as prescribed by your doctor. It is usually taken once or twice daily, preferably in the morning on an empty stomach or as directed. Swallow the tablet whole with water; do not crush, chew, or break it. Take it at the same time each day for best results. Do not stop taking this medicine suddenly without consulting your doctor. Always follow your doctor's or pharmacist's specific instructions regarding dosage and timing.

How it works

Isosorbide Mononitrate works by relaxing and widening blood vessels in the body, particularly those supplying the heart. This widening (vasodilation) reduces the workload on the heart and improves blood flow to the heart muscle. By allowing more oxygen-rich blood to reach the heart, it helps prevent chest pain and reduces the frequency of angina attacks. The medicine also reduces the amount of work the heart needs to do by decreasing the pressure in blood vessels.
