Sildenafil is a type of medication used to treat erectile dysfunction, a condition where men find it difficult to get or maintain an erection. It is the generic version of the brand name drug Viagra.
Sildenafil increases blood flow to the penis so you can get and keep an erection.
You can take Sildenafil as needed although you should only use it once in any 24 hour period. Sildenafil is available as a pill in 25mg, 50mg and 100mg, depending on what you and your doctor determine to be most suitable for your needs.
Usually, Sildenafil will start to work within 30 to 60 minutes. If you’re wondering when to take Sildenafil, you can take it up to four hours before sexual activity.
If you have erectile dysfunction and normally find it difficult to get or maintain an erection, Sildenafil might cause your erection to feel bigger but it will not make your penis physically larger than its regular size.
Sildenafil is not a treatment for premature ejaculation, so it usually won’t impact the amount of time you can have sex for before you ejaculate.
Sildenafil won’t make you hornier or help you feel sexually aroused when you otherwise wouldn’t be interested in sex. Sildenafil simply makes it easier to get an erection when you’re already sexually aroused.
Sildenafil isn’t for everyone. You should not take Sildenafil if any of the following conditions apply to you:

If you develop an erection that lasts longer than 3 hours please go to the emergency department - this is a rare but dangerous side effect called priapism.

It is recommended that you see a doctor in person for this issue, for a full physical exam and blood work to determine if there is an underlying cause like diabetes, vascular disease or low testosterone
