Nitroglycerin is the medication of choice to treat acute attacks of chest pain (or angina) and one of the first-line medications to prevent chest pain for patients with blockages in their coronary arteries. There is also some role for nitroglycerin in the treatment of chronic or congestive heart failure. It is one of the most prescribed medications of its kind and you can order it here for a fraction of the price!
Nitroglycerine may also be marketed as: Nitro-Dur, Nitrostat, Nitro-Bid and more.
Each Nitroglycerin bottle contains 25 X 6.4mg capsules
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.
Nitroglycerin 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.
Take Nitroglycerin 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).
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Nitroglycerin rectal can cause severe headaches, which may occur each time you use the medication. Your doctor may recommend treating fever and pain with an aspirin free pain reliever such as acetaminophen (Tylenol). Follow the label directions or your doctor's instructions about how much of this medicine to use.
