Product Description
Isosorbide dinitrate 10mg tablets are a medication used to prevent chest pain (angina) in patients with coronary artery disease. It belongs to a class of drugs known as nitrates, which work by relaxing and widening blood vessels, allowing blood to flow more easily to the heart.
How It Works:
Isosorbide dinitrate is a vasodilator, meaning it relaxes the muscles in the walls of blood vessels, causing them to widen. This widening of blood vessels, particularly the veins, reduces the amount of blood returning to the heart, which decreases the workload on the heart. This also reduces the pressure within the heart, making it easier for the heart to pump blood.
Uses:
- Prevention of Angina: Isosorbide dinitrate is primarily used to prevent angina attacks, which are episodes of chest pain caused by reduced blood flow to the heart. It is not intended to relieve chest pain once it occurs.
Dosage and Administration:
Isosorbide dinitrate 10mg tablets are typically taken 2 to 3 times daily, usually at evenly spaced intervals throughout the day. The exact dosage and frequency will depend on your individual condition and response to treatment. Always follow your doctor's instructions carefully.
Side Effects:
Common side effects of isosorbide dinitrate include:
- Headache: This is a common side effect, often a sign that the medication is working. It may gradually subside as your body adjusts to the medication. Over-the-counter pain relievers can help manage headaches.
- Dizziness: This can occur, especially when you first start taking the medication. Get up slowly from a sitting or lying position to minimize dizziness.
- Lightheadedness: Lightheadedness is another common side effect.
- Flushing: You may experience a feeling of warmth or redness in your skin.
- Nausea: Some people may experience nausea.
More serious side effects are rare but can include:
- Fainting: If you experience fainting, seek medical attention immediately.
- Fast/Irregular/Pounding Heartbeat: Contact your doctor immediately if you experience a rapid or irregular heartbeat.
- Allergic Reaction: A very serious allergic reaction is rare but can occur. Symptoms include rash, itching/swelling (especially of the face, tongue, or throat), severe dizziness, and trouble breathing. Seek immediate medical help if you notice any of these symptoms.
Precautions:
- Allergies: Tell your doctor if you are allergic to isosorbide dinitrate or any other ingredients in the medication.
- Medical History: Inform your doctor about any pre-existing medical conditions, especially low blood pressure, congestive heart failure, or kidney disease.
- Pregnancy and Breastfeeding: Discuss the risks and benefits of isosorbide dinitrate with your doctor before taking it during pregnancy or breastfeeding.
- Alcohol and Marijuana: Avoid alcohol and marijuana, as they can increase dizziness.
- Driving and Operating Machinery: Isoxsuprine can cause dizziness. Avoid driving, operating machinery, or engaging in activities requiring alertness until you know how the medication affects you.
Drug Interactions:
Isoxsuprine can interact with other medications, including those used to treat high blood pressure and other heart conditions. Tell your doctor about all medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements.
Important Notes:
- Don't Share: Do not share this medication with others.
- Missed Dose: If you miss a dose, take it as soon as you remember. If it is near the time of your next dose, skip the missed dose and take your next dose at the regular time. Do not double the dose to catch up.
- Storage: Store isosorbide dinitrate tablets at room temperature away from light and moisture. Keep all medications away from children and pets.
