Imdur 30 Tablet PR is used to prevent and manage chest pain (angina pectoris) caused by coronary artery disease. It helps lower the frequency and severity of angina attacks by improving blood flow to the heart muscle.

It contains isosorbide mononitrate, a nitrate medicine. Swallow the prolonged-release tablet whole as prescribed, without crushing or chewing. Take it regularly as prescribed for long-term prevention, and do not stop taking it suddenly as this may cause rebound chest pain.

Heart-healthy habits complement your medical treatment for coronary artery disease. Maintain a balanced low-fat diet, engage in light exercise as advised by your doctor, avoid tobacco smoke, and monitor your blood pressure regularly.

Before taking this medicine, tell your doctor if you have low blood pressure, liver or kidney disease, glaucoma, thyroid disorders, or recent head injury. Inform your doctor if you experience persistent dizziness, severe headaches, or fainting spells.
