Angina, or chest pain, happens when the heart isn’t getting enough blood. Erectile dysfunction (ED) is when a man has trouble getting or maintaining an erection. Both are pretty common.
Nitrates like isosorbide help with angina, while PDE5 inhibitors like sildenafil (Viagra) help with ED. Isosorbide mononitrate and isosorbide dinitrate are two common nitrates used to prevent and treat angina.
The problem is, combining these medications can be really dangerous. Taking Viagra or other PDE5 inhibitors with isosorbide can cause a drastic drop in blood pressure.
If you’re taking isosorbide, you might wonder how long after taking isosorbide can you take Viagra safely, if at all. This article will cover the risks, waiting times, and safer alternatives.
