Glyceryl trinitrate is used to relieve angina. It relaxes the blood vessels, allowing more blood to flow to the heart.
Glyceryl trinitrate tablets should be placed under the tongue and allowed to dissolve. Do not crush, chew or swallow glyceryl trinitrate tablets.
Stop what you are doing. Sit down and place 1 tablet under your tongue.
If your angina is relieved by rest or your tablet, you can resume your activities gently.
If after 5 minutes you still have angina, place 1 more tablet under your tongue.
If you still have angina after 5 more minutes, treat as a heart attack – call an ambulance (dial 111) immediately.
Some medicines available without a prescription may react with glyceryl trinitrate including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
