Should I take viagra on an empty stomach ?

Generic Viagra (Sildenafil) can be taken with or without food, but it works better if you take it first thing in the morning. If you take sildenafil with or after a meal, it takes longer for it to start working.

In Addition, You should take your sildenafil dose one hour before you intend to have sex.

Within 25 minutes to an hour after taking the fildena tablet, you should be able to get an erection in response to sexual stimulation, and this should last for up to five hours.

A dose of sildenafil should not be taken more than once every 24 hours.
