If Viagra isn’t working for you, wait two to three hours after your last meal before taking it again. Wait for Viagra to take effect.
Viagra is a fast-acting drug, but its effects aren’t immediate. It’s best to take sildenafil oral jelly at least an hour before you plan to have sex, as this allows your body to fully absorb the drug.
Viagra works by increasing blood flow to your penis’ erectile tissue. Your penis, like the rest of your body’s organs, requires a constant, steady supply of oxygenated blood to function properly.
When you’re aroused, your body causes an erection by increasing the flow of blood into the soft tissue of your penis.
