NitroQuick

Pronunciation: NYE-troe-GLIS-er-in
Generic Name: Nitroglycerin
Brand Name: Nitrostat

NitroQuick is used for:

Preventing or relieving a sudden attack of angina (chest pain) caused by heart disease. It may also be used for other conditions as determined by your doctor.

NitroQuick is a nitrate. It works by dilating (widening) blood vessels. Chest pain occurs when the heart needs more oxygen than it can get. Dilating blood vessels allows blood to flow more easily. This reduces the heart's workload and the amount of oxygen needed by the heart.

Do NOT use NitroQuick if:

• you are allergic to any ingredient in NitroQuick


• you have increased pressure in the head


• you have severe anemia


• you are also taking a phosphodiesterase type 5 (PDE5) inhibitor (eg, sildenafil, tadalafil, vardenafil)

Contact your doctor or health care provider right away if any of these apply to you.

Before using NitroQuick:

Some medical conditions may interact with NitroQuick. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

• if you have anemia, low blood pressure, dehydration, or low blood volume

Some MEDICINES MAY INTERACT with NitroQuick. Tell your health care provider if you are taking any other medicines, especially any of the following:
