Isdn How to Take

Isosorbide dinitrate belongs to the class of medications called anti-anginals. It is used to prevent chest pain associated with Angina. It works by relaxing blood vessels and increasing the blood and oxygen supply to the heart. Isosorbide dinitrate may reduce the number, length, and severity of angina attacks. Tolerance for exercise may be increased and the need for fast-acting Nitroglycerin (tablets and spray) may be reduced.

Isdn Dosage

Oral tablets: The recommended dose of isosorbide oral tablets for long-term prevention of angina is 5 mg to 30 mg taken 4 times daily, leaving a period of time called the nitrate-free period (as discussed with your doctor) where the body is relatively free of the medication. For example, the medication may be taken at 8 am, 12 pm, 4 pm, and 8 pm. This schedule allows the medication to keep working effectively as it prevents your body from getting too used to its effects.

Sublingual tablets (tablets dissolve in 20 seconds under the tongue): Isosorbide sublingual (under the tongue) tablets are dissolved under the tongue to prevent an angina attack. Dissolve 1 or 2 tablets (5 mg to 10 mg) under the tongue, between the cheek and gum, or between the lip and gum every 2 to 4 hours. An extra dose of 5 mg to 10 mg may be taken before stressful situations that are likely to cause an angina attack. Do not eat, drink, smoke, or chew tobacco while the tablet is dissolving. Talk to your doctor about the dose and nitrate-free period that are right for you.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Isdn (Isosorbide-dinitrate) exactly as prescribed by the doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is close to the time of your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Isdn (Isosorbide-dinitrate) at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Isdn Warnings

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health.

Low Blood Pressure: When isosorbide dinitrate relaxes the blood vessels, the blood vessels become wider, allowing blood to flow more easily. This can cause blood pressure to decrease. While this usually isn't a problem, some people experience dizziness, headache or fainting, particularly when rising from a seated or lying position. If you have low blood pressure or experience these symptoms when you are taking isosorbide dinitrate, talk to your doctor.

Tolerance: The body can get used to the effects of isosorbide dinitrate (develop a tolerance), especially if the medication is taken throughout the day without a "nitrate-free period" (a 10 to 12-hour break from the medication). If you find that your symptoms of angina are getting worse or lasting longer, call your doctor.

Withdrawal: Stopping Isdn (Isosorbide-dinitrate) suddenly may occasionally aggravate chest pain or other symptoms of angina. To avoid possible withdrawal effects, isosorbide dinitrate should be gradually reduced and not stopped suddenly. Talk to your doctor about how to stop the medication safely.

Pregnancy: Isdn (Isosorbide-dinitrate) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Isdn (Isosorbide-dinitrate), contact your doctor immediately.
