NITROGLYCERIN EXTENDED-RELEASE CAPSULE - ORAL
USES: Nitroglycerin extended-release capsules are used to prevent chest pain (angina) in people with a certain heart condition (coronary artery disease). This medication belongs to a class of drugs known as nitrates. Angina occurs when the heart muscle is not getting enough blood. This drug works by relaxing and widening blood vessels so blood can flow more easily to the heart.
This medication will not relieve chest pain once it occurs. It is also not intended to be taken just before physical activities (such as exercise, sexual activity) to prevent chest pain. Other medications may be needed in these situations. Consult your doctor for more details.
HOW TO USE: Take this medication by mouth, usually 3 to 4 times daily or as directed by your doctor. It is important to take the drug at the same times each day. Do not change the dosing times unless directed by your doctor. The dosage is based on your medical condition and response to treatment.
Swallow this medication whole. Do not crush or chew the capsules. Doing so can release all of the drug at once and may increase your risk of side effects.
Use this medication regularly to get the most benefit from it. Do not suddenly stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.
Although unlikely, when this medication is used for a long time, it may not work as well and may require different dosing. Tell your doctor if this medication stops working well (for example, you have worsening chest pain or it occurs more often).
SIDE EFFECTS: Headache, dizziness, lightheadedness, nausea, and flushing may occur as your body adjusts to this medication. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Headache is often a sign that this medication is working. Your doctor may recommend treating headaches with an over-the-counter pain reliever (such as acetaminophen, aspirin). If the headaches continue or become severe, tell your doctor promptly.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: fainting, fast/irregular/pounding heartbeat.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
