How long do erectile dysfunction (ED) medications work?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
There is no one-time-fits-all answer. How long your erectile dysfunction (ED) medication lasts is probably a little different for you than it would be for your buddy down the street. Your body may metabolize medication differently based on your age and if you have liver or kidney problems. How long it works depends on how big a dose your doctor prescribed. One thing all guys should remember: You'll get the best results from your ED medication by relaxing, preparing for sex, and enjoying the moment.

The amount of time that medications for erectile dysfunction last depends on the particular medication. Viagra and Levitra are typically effective for up to four hours after you take them. Cialis is effective for up to 36 hours.

In order to work, all three drugs require sexual stimulation and arousal; you won't experience an erection unless you are sexually aroused first.
