What Isosorbide mononitrate ER is

A long-acting nitrate. It widens blood vessels so the heart needs less oxygen and gets more blood, which helps prevent chest pain.

What it’s for

Preventing angina (chest pain from reduced blood flow to the heart). It does not stop an attack that has already started.

How it’s taken

By mouth, once a day in the morning. Swallow it whole or split on the score line; don’t crush or chew it.

Good to know

Never take it with erection medicines like sildenafil or tadalafil: together they can drop blood pressure to dangerous levels. Headache is common at first. Chest pain that is new, worse, or doesn’t ease is an emergency: call 911.
