Vidalista 2.5 is a medication that men with erectile dysfunction can take. The erection is facilitated for males by an increase in blood flow to the penis. Your penis's blood vessels relax when you experience sexual excitement, allowing blood to flow into it. Despite its great effectiveness, it needs to be taken 30-60 minutes before having sex. Avoid drinking as it can exacerbate vertigo and make it more difficult to have an erection. Tadalafil should not be taken if you have recently used nitrates, had a heart attack within the last three months, had a stroke, or had heart failure within the last six months.
