Q. Does Isosorbide Dinitrate lower blood pressure?
Yes, Isosorbide Dinitrate lowers blood pressure. This medicine widens the blood vessels and decreases the resistance in them, causing a fall in blood pressure. This fall in blood pressure may in turn decrease the heartbeat which can lead to angina. This medicine should be avoided in people who already have low blood pressure. Discuss with your doctor if you have any concerns.
Q. Can I take sildenafil while taking Isosorbide Dinitrate?
No, you should not take sildenafil along with Isosorbide Dinitrate. Both these medicines lower blood pressure and belong to the same class. Taking these two medicines together may cause significant decrease in blood pressure which can cause fainting or even a heart attack. Along with this, avoid taking other medicines which belong to the same class such as vardenafil and tadalafil.
