Each one works to increase blood flow to the penis by increasing your body’s nitric oxide to create and maintain an erection during sexual intercourse. These medications only cause erections during sexual stimulation and do not increase an individual’s sexual appetite.
The top three erectile dysfunction medications are Viagra, Levitra, and Cialis. Although they are all made to have the same result, each one has a different chemical makeup that affects how each individually work. Your doctor will take this into account along with your current medical health when prescribing a medication to you.
Not all who suffer from erectile dysfunction can take medication; they may not be safe if you are or have:
- Allergic to certain drugs
- Scheduled for an upcoming surgery
- Heart problems
- High or low blood pressure
- Had a stroke previously
- Liver disease
- Kidney disease
- Taking nitrate drugs
- Taking alpha blockers
As with any medication, always consult with your doctor first.

- Flushing (feeling warm)
