To use amyl nitrite:
- When you begin to feel an attack of angina starting (chest pains or a tightness or squeezing in the chest), sit down. Then crush the cloth-covered glass capsule containing amyl nitrite between your finger and thumb. Pass it back and forth close to your nose and inhale the vapor several (1 to 6) times. Since you may become dizzy, lightheaded, or faint soon after using amyl nitrite, it is best to sit or lie down rather than stand while the medicine is working. If you become dizzy or faint while sitting, take several deep breaths of air and either bend forward with your head between your knees or lie down with your feet elevated.
- Remain calm and you should feel better in a few minutes.
Use this medicine exactly as directed by your doctor , and do not use more than your doctor ordered. Using too much amyl nitrite may cause a dangerous overdose. If the medicine does not seem to be working as well after you have used it for a while, check with your doctor. Do not increase the dose on your own.
