What is Isosorbide Mononitrate?

Isosorbide Mononitrate is a medicine used to help people with heart problems, especially angina (chest pain). It helps relax and widen blood vessels so the heart gets more oxygen. This makes it easier for the heart to pump blood and reduces chest pain.

How Does It Work?

This medicine belongs to a group called nitrates. When taken, it turns into nitric oxide, which helps blood vessels relax. This improves blood flow and reduces the heart’s workload.

Uses of Isosorbide Mononitrate 10mg

Doctors usually prescribe this medicine for:

• Preventing angina (chest pain) caused by heart disease.
• Improving blood flow in people with heart conditions.
• Reducing strain on the heart, making it work more efficiently.

Important: This medicine does not treat sudden chest pain. For that, doctors often recommend nitroglycerin under the tongue.

How to Take It

• Usually taken once or twice a day, as prescribed by a doctor.
• Swallow the tablet whole with water.
• Take it at the same time every day for the best results.
• Do not stop suddenly without talking to your doctor.

Possible Side Effects

Some people may experience side effects, but not everyone. Common side effects include:

• Headache (this is common but usually gets better with time)
• Dizziness or lightheadedness (especially when standing up)
• Nausea (feeling sick)
• Flushing (redness in the face or skin)

Serious Side Effects (Rare but Important)

• Severe dizziness or fainting
• Fast or irregular heartbeat
• Swelling in the legs or feet
• Trouble breathing

If you have serious side effects, contact your doctor right away.

Who Should Not Take It?

• People allergic to nitrates.
• Those taking medicines for erectile dysfunction (Viagra, Cialis, Levitra)—this can cause a dangerous drop in blood pressure.
• People with very low blood pressure or certain heart problems.

Precautions

• Avoid alcohol, as it can make dizziness worse.
• Stand up slowly from sitting or lying down to prevent dizziness.
• Let your doctor know about all other medicines you are taking.
