Sildenafil vs tadalafil, practically speaking

Both are PDE5 inhibitors and both are available as inexpensive generics. A licensed provider chooses between them based on your health and how you live — but knowing the practical differences helps you have that conversation.

Sildenafil

Typically taken as needed, roughly an hour before activity. Effects generally last several hours. Heavy or fatty meals can slow its absorption, which is the most common practical complaint. It's the most prescribed ED medication in the world, with decades of clinical history.

Tadalafil

Known for a much longer duration — effects can last more than a day, which is why it earned its nickname in the press. It also comes in a low-dose daily version, which removes timing from the equation entirely for men who prefer spontaneity. Food has less effect on absorption.

Which is right for you

That's genuinely a provider's call — dosing, your medications, and your cardiovascular health all factor in. What you can usefully think about beforehand: do you want on-demand or daily? Does meal timing bother you? Those preferences are exactly what our quiz captures.
