Fast-Acting Nitroglycerin
Nitroglycerin relieves angina (chest pain) by getting more blood and oxygen to your heart. Fast-acting nitroglycerin stops an angina attack. Follow the steps below for taking fast-acting nitroglycerin.
To Stop an Angina Attack
If you use tablets:
- Sit down.
- Place one tablet under your tongue. Or place it between your lip and gum or between your cheek and gum.
- Let the tablet dissolve all the way. Do not swallow or chew the tablet.
- Do not eat, drink, smoke, or chew tobacco as the tablet is dissolving.
If you use spray:
- Sit down. Open your mouth and hold the sprayer just in front of your mouth.
- Press the button on the top. Spray once under your tongue or inside your cheek. Do not inhale.
- Close your mouth. Then wait a few seconds before you swallow.
After taking one tablet or spraying once:
- Sit for 5 minutes.
- If the angina goes away, rest for a while and continue your normal routine.
Call 911 or have someone drive you to an emergency room if your angina lasts longer than 5 minutes and 1 tablet or 1 spray has not relieved it. Do not delay-you may be having a heart attack!
Precautions
- Limit the amount of alcohol you drink. Too much alcohol can cause dizziness or fainting.
- Tell your healthcare provider about any medications, supplements, or herbs you use. Nitroglycerin can interact with other medications and cause serious problems. NOTE: Do not take Viagra, Levitra, or Cialis at any time if you are on nitroglycerin.
- Check the expiration date. Nitroglycerin can lose its effectiveness over time.
