How effective are Erectile dysfunction pills?

ED drugs produce an erection sufficient for intercourse in about 70% of men. But the results vary quite a bit from one individual to another. A man with nerves or arteries damaged by prostate surgery, diabetes, or cardiovascular disease will not respond as strongly to ED drugs. "There are some men in whom none of these drugs work," Dr. Liou says.

How quickly do ED pills work?

How soon the drugs start working ranges from 15 to 60 minutes. Neither Viagra nor Levitra will work if you take them after a meal, which blocks their absorption. However, neither Cialis nor Stendra interact with food this way. The onset time determines how soon you can engage in intercourse. Stendra and daily-use Cialis are closest to being an "on demand" erectile drug; using the others requires more planning.

How to use ED pills properly

Dr. Liou says that some men come to him after getting a prescription from their primary care doctors, claiming that the drug doesn't work. Sometimes it's because they used it incorrectly. "The biggest misconception is that these drugs are an on/off switch for erections," Dr. Liou says. But the drugs don't work well without sexual stimulation. "During that time, you need to be with your partner and have foreplay," Dr. Liou says. "Don't take it, do the taxes or the dishes, and then meet at the bedroom thinking you'll be ready to go. It's not like that."
