Hi, I would like to know how long does it take for Viagra to be effective? I assume it would help me with erectile disorder, but don’t know how much in advance I need to take it?
Hi, I think that Viagra reacts quite fast, based on my experience. Viagra is rapidly absorbed, and within 30 to 120 minutes it reaches maximum concentrations, on an empty stomach. You should avoid taking fatty meals before using Viagra, as they decease it’s effectiveness. Some studies suggest that it’s effect lasts for about 4 hours, but some other didn’t confirm this result. An erection is the result of an increased blood flow into certain structures of the penis, but if it provokes increased blood flow in heart or brain consequences can be devastating. So, pay attention when using it, and perhaps try lower doses of Viagra 25mg and 50mg.
