Tips on how to properly use nitroglycerin

[MUSIC PLAYING]

If you have coronary artery disease, your health care provider may have prescribed you nitroglycerin. Many people with coronary artery disease

use nitroglycerin to relieve their chest pain. Nitroglycerin works by relaxing the coronary arteries,

which increases blood supply and oxygen to the heart. Nitroglycerin comes in powder, pill, and spray form and is usually taken sublingually,

or under the tongue. When you begin to feel chest pain or tightness starting, take a seat. You may become dizzy, lightheaded, or faint soon

after using nitroglycerin. So it is safer to sit rather than stand while the medicine is working.

Place the nitroglycerin powder or tablet under your tongue. If you use the oral spray, spray it on or under your tongue.

If you become dizzy or faint while sitting, take several deep breaths and lean forward with your head between your knees.

Try to stay calm. You should feel better in a few minutes. If you are taking the nitroglycerin powder, close your mouth and allow the medicine

to dissolve without swallowing. Try to breathe normally. Do not rinse out your mouth or spit for five minutes after taking nitroglycerin powder.

Never chew, crush, or swallow nitroglycerin sublingual tablets. This medicine works more quickly when

it is absorbed through the lining of your mouth. Extended relief nitroglycerin tablets may be swallowed, but make sure you swallow them whole.

They should not be split, crushed, or chewed. Make sure you keep your nitroglycerin medication away from moisture, heat, and direct sunlight.

Keep sublingual tablets in the original glass bottle. Be sure to check the expiration date on the label and replace any outdated medicine.

If you have medicine you no longer use, ask your doctor or pharmacist how to dispose of it properly.
