Additional Information

Why is this medication prescribed

Isosorbide is used to prevent or treat chest pain (angina). It works by relaxing the blood vessels to the heart, so the blood and oxygen supply to the heart is increased.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Other uses for this medicine

Isosorbide tablets are also used with other drugs to treat congestive heart failure. Talk to your doctor about the possible risks of using this drug for your condition.

What other information should I know

Keep all appointments with your doctor and the laboratory.

Isosorbide regular and extended-release tablets or capsules should not be used for acute angina attacks. Continue to use isosorbide sublingual or chewable tablets to relieve chest pain that has already started.

If headache continues, ask your doctor if you may take acetaminophen. Your isosorbide dose may need to be adjusted. Do not take aspirin or any other medication for headache while using isosorbide unless you doctor tells you to.

The tablets may cause a sweet, tingling sensation when placed under your tongue. This sensation is not an accurate indicator of drug strength; the absence of a tingling sensation does not mean that the drug is not working.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
