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.

Most important: NitroQuick may cause dizziness, lightheadedness, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use NitroQuick with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

Check with your doctor before you drink alcohol while you are using NitroQuick. Drinking alcohol may increase the risk of low blood pressure with NitroQuick.

NitroQuick may cause dizziness, lightheadedness, or fainting. Sit down while taking NitroQuick to avoid falling caused by lightheadedness or dizziness.

NitroQuick can cause tingling or burning when you put it under your tongue. However, lack of tingling or burning does not mean the medicine is not working.

Contact your doctor right away if you develop slow heartbeat or new or worsening chest pain after you take NitroQuick.

Do NOT take more than the recommended dose or use more often than prescribed without checking with your doctor.

Keep medicine in the original glass bottle with cap tightly closed. Throw away the cotton inside once the bottle is opened.

Tell your doctor or dentist that you take NitroQuick before you receive any medical or dental care, emergency care, or surgery.

NitroQuick may interfere with certain lab tests, including certain cholesterol tests. Be sure your doctor and lab personnel know you are using NitroQuick.

Lab tests, including heart function, blood pressure, and blood electrolyte levels, may be performed while you use NitroQuick. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
