Available by prescription only, Nitrostat can help relieve attacks of chest pain (angina) or prevent an attack that is expected to occur. It comes in the form of a tablet that dissolves in the mouth. This product works by relaxing the veins and arteries in the body to improve blood flow to the heart. Side effects may include headaches, lightheadedness, and dizziness.

What Is Nitrostat?

Nitrostat® (nitroglycerin tablets) is a prescription medication used to treat sudden episodes of chest pain (angina). It can also be used just before physical activity, such as exercise or sexual intercourse, to help prevent anticipated chest pain.

Who Makes This Medication?

Nitrostat is made by Pfizer, Inc.

How Does Nitrostat Work?

Nitrostat works by relaxing the veins and arteries in the body. With the arteries and veins relaxed, the heart does not need to work so hard and does not require as much oxygen. Because angina is usually caused when there is not enough oxygen to meet the heart's needs, Nitrostat can help relieve angina attacks.

When and How to Use It

Some general considerations to keep in mind during treatment with Nitrostat include the following:
  • This medication comes in the form of a tablet that is dissolved under the tongue or between the cheek and gum. Do not chew or swallow the tablets.
  • If your chest pain continues after one tablet, you can take another one five minutes later. If chest pain is still not relieved after a third tablet, seek immediate medical attention.
  • Nitrostat can also be used 5 to 10 minutes before activity that is anticipated to cause chest pain.
  • For the medication to work properly, it must be taken as prescribed.
