When using Fildena 200, should I stay away from nitrates?

Fildena 200 contains sildenafil citrate, which is a vasodilator—it relaxes blood vessels to improve blood flow. Nitrates do the same, and using both together can make your blood pressure fall to unsafe levels. Taking Fildena 200 while on these drugs can result in fainting, dizziness, heart attack, or even stroke. Even if you’re not sure whether your medication contains nitrates, you should always inform your doctor about all the drugs you're taking before using Fildena 200. This includes prescription medications, over-the-counter drugs, and herbal supplements.
