1. Why am I using MONODUR®?
MONODUR

MONODUR is used to prevent angina.
Angina is a pain or uncomfortable feeling in the chest, often spreading to the arms
or the neck and sometimes to the shoulders and back. This is caused by too little
blood and oxygen getting to the heart.
The pain of angina is usually brought on by exercise or stress.
MONODUR works by relaxing the blood vessels, letting more blood and oxygen reach the
heart.

what dose to take.
