Common Questions about Isosorbide Mononitrate

Is isosorbide mononitrate a blood pressure medicine?

Isosorbide mononitrate is not a blood pressure medicine. It is a vasodilator that is used to prevent chest pain (angina attacks) in people with coronary heart disease. However, isosorbide mononitrate can cause a dangerous drop in blood pressure if you drink alcohol while on this medicine or take it with erectile dysfunction drugs like sildenafil (Viagra).

Who should not take isosorbide mononitrate?

People who are allergic to isosorbide mononitrate should not take this medicine. Also, anyone experiencing signs and symptoms of a heart attack should not take this medicine and instead call 911 for emergency medical attention.

Can I suddenly stop taking isosorbide mononitrate?

Do not suddenly stop taking isosorbide mononitrate without talking to your doctor. This can cause severe pain during angina attacks, more frequent chest pain episodes, or longer-lasting angina attacks.

Is isosorbide mononitrate the same as nitroglycerine?

Isosorbide mononitrate and nitroglycerine are not the same, although both are organic nitrates that act as vasodilators. Isosorbide mononitrate works slowly and is for the prevention of angina. It cannot be used to treat an acute angina attack or heart attack. Nitroglycerine works quickly and can be used to treat an acute angina attack or heart attack.

What is the best time of day to take isosorbide mononitrate?

If you are taking the immediate-release isosorbide mononitrate tablets, your doctor will tell you when to take the two doses (7 hours apart). If you are taking the extended-release tablets, you should take the medicine once a day in the morning. Follow the dosing schedule recommended by your doctor carefully. This medicine works best if there is a "drug-free" period every day when your body is not exposed to it. Your doctor will tell you how to schedule your doses to allow for a drug-free period during the day.
