Heart Disease and Angina (Chest Pain)
Something to Remember About Angina
If you have angina, carry nitroglycerin with you at all times; you never know when you will need it. Nitroglycerin must be kept in a dark container. Keep it away from heat or moisture. Check the expiration date on the container. Once the container of nitroglycerin tablets is opened, it must be replaced every three months. The spray form has a longer shelf life and should be replaced every 2 years.
