When it comes to treating erectile dysfunction, the best PDE5 inhibitor, a class of drugs that relaxes blood vessels to improve flow. Also known as phosphodiesterase type 5 inhibitors, these medications are the most common prescription solution for ED—and not all of them are the same.

The sildenafil, the active ingredient in Viagra and Zenegra. Also known as generic sildenafil, it’s the original and still widely used. It usually starts working in 30 to 60 minutes and lasts about 4 to 5 hours. Then there’s tadalafil, the active ingredient in Cialis. Also known as Cialis, it takes a bit longer to kick in but can last up to 36 hours. That’s why some men call it the "weekend pill." vardenafil, found in Levitra and Staxyn. Also known as Levitra, it’s similar to sildenafil but may work better for men with diabetes. Each one has different side effects too—headaches, flushing, or upset stomach are common, but some men tolerate one better than the others.

Sildenafil might be your pick. Want flexibility without planning ahead? Tadalafil could be the answer. And if you’ve tried one and it didn’t click, that doesn’t mean ED treatment won’t work—it just means you haven’t found the right match yet.
