Uses of Isosorbide-5-Mononitrate

  • Isosorbide-5-mononitrate is used for the prevention and long-term management of angina pectoris (chest pain) associated with coronary artery disease. 
  • It helps improve blood flow to the heart by dilating blood vessels and reducing the heart’s workload. 
  • This medication is also used in certain cases of heart failure to improve symptoms and enhance exercise tolerance. However, it is not suitable for immediate relief of acute angina attacks.

Side effects of Isosorbide-5-Mononitrate

  • Headache
  • Dizziness
  • Nausea
  • Fatigue
  • Low blood pressure (hypotension)
  • Increased heart rate (tachycardia)

How Isosorbide-5-Mononitrate works

  • Isosorbide-5-mononitrate is a nitrate vasodilator.
  • It works by relaxing and widening blood vessels. This reduces the heart’s oxygen demand and allows more blood to flow easily, preventing chest pain. 
  • By decreasing the heart's workload, it helps improve symptoms of angina and enhances exercise capacity in heart failure patients.

Other Medications to Avoid

Other medications to avoid include certain antihypertensives, alcohol, and ergot alkaloids. Always inform your doctor about any other medications you are taking to prevent potential interactions.

Overdose and Missed Dose

  • An overdose of Isosorbide-5-mononitrate can cause severe hypotension, dizziness, fainting, and palpitations. In such cases, immediate medical attention is necessary. 
  • If a dose is missed, take it as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and continue with the regular schedule. Do not take a double dose to make up for the missed one.

Management of Side Effects

  • Headache is a common side effect of Isosorbide-5-mononitrate. To manage this, you can use mild pain relievers like paracetamol after consulting your doctor. If dizziness or low blood pressure occurs, sit or lie down immediately until symptoms improve. Staying hydrated and avoiding sudden movements can help reduce dizziness. If side effects persist or worsen, seek medical advice.

Use in Driving and Operating Machinery

Use in Pregnancy and Lactation

Special Dietary and Lifestyle Recommendations
