What If I Overdose on This Medicine?An overdose with this medication can be dangerous. If you or someone else may have taken too much, seek immediate medical attention.
How Does It Work?The nitroglycerin tablet 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, nitroglycerin tablets can help relieve angina attacks.
When and How to Use Nitroglycerin TabletsSome general considerations to keep in mind during treatment with nitroglycerin tablets 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.
- Nitroglycerin tablets 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.
