Taking prescription oral erectile dysfunction (ED) medications recreationally — without a medical need — carries possible health risks. For example, you could:
- Get counterfeit drugs. Currently, oral ED medications, such as sildenafil (Viagra), tadalafil (Cialis) and vardenafil (Levitra, Staxyn), require a prescription. Obtaining these medications without a prescription, such as from an unlicensed online pharmacy, puts you at risk of taking a medication that might contain no active ingredient or the wrong medicine.
- Have an adverse effect or drug interaction. Prescription erectile dysfunction medications might not work or might be dangerous for you if you take nitrate drugs, if you have very low blood pressure (hypotension), or if you have heart disease or heart failure. It's important to talk to a doctor before taking any prescription ED medication. A prescription erectile dysfunction medication could also cause a severe reaction if used with other recreational drugs, such as cocaine.
- Become psychologically dependent on the medication. Some research suggests that men who use ED medications recreationally might begin to lose confidence in their ability to achieve and maintain an erection without them. Recreational use of ED medications could also cause men to develop unreasonable expectations for their erectile performance.
Prescription oral erectile dysfunction medications aren't intended for recreational use by men who don't have ED. If you're concerned about your ability to achieve or maintain an erection, talk to your doctor. He or she can help determine if you have an underlying condition that needs treatment or if you might benefit from medication or other treatments.
