What Is Sildenafil?

Sildenafil, or the generic form of Viagra, is the most popular treatment for ED.


It is clinically proven and has improved erection in up to 84% of men, promoting erection for 4 to 6 hours when there is sexual arousal.

How Does Sildenafil Work?

It improves blood flow to the penis, allowing for harder, firmer erections.

This alleviates many of the common causes of ED which include heart disease, high cholesterol and blood pressure, and diabetes.

Who Can & Can't Take Sildenafil?

Most adult men can take Sildenafil for ED.


Sildenafil is NOT suitable for:
- People who have had an allergic reaction to sildenafil (Viagra) or any other medicines in the past
- People that are taking medicines called nitrates for chest pain
- People with serious heart or liver problem
- People that have recently had a stroke or a heart attack
- People that have low blood pressure
- People that have a rare inherited eye disease, such as retinitis pigmentosa

How To Take Sildenafil?

Take one pill up to 4 hours before you want to have sex. Sildenafil starts to work within 30-60 mins, and maximum erection potential happens around the 1 hour mark. Swallow the tablet whole, with at least one full glass of water. Recommended to be taken without food.

*Do not take more than one pill within 24 hours.

What Are The Side Effects?

As with any medication, you may experience some side effects, with the most common being headaches, feeling sick, hot flushes and dizziness. Many men have no side effects or only mild ones.
