Nitroglycerin ER Side Effects

What should I watch for?

Check your heart rate and blood pressure regularly while you are using this medicine. Ask your doctor or health care professional what your heart rate and blood pressure should be and when you should contact him or her. Tell your doctor or health care professional if you feel your medicine is no longer having any effect.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can make you more drowsy and dizzy. Avoid alcoholic drinks.
