Erectile Dysfunction (ED)

Erectile dysfunction is the inability to get and keep an erection long enough to have sexual intercourse. If erectile dysfunction is an on-going issue, you should consult with your doctor to find a suitable solution.

What Medications Are Available?

The medications listed below will relax your muscles and increase blood to your penis: 

  • Avanafil (Steindra)

  • Sildenafil (Viagra) 

  • Tadalafil (Cialis) 

  • Vardenafil (Levitra, Staxyn)

These medications all have the function but have subtle differences in how long they last, and how fast they begin working. Levitra will take approximately 30 minutes to start working, and the effects will last up to five hours longer than Viagra. Staxyn and Levitra are made with the same active ingredients and you can expect it to start working in approximately 15 minutes.

Precautions to Take

You should not use erectile dysfunction medication if you are also on nitrates (i.e. nitroglycerin) for chest pain, as the combination could lead to dangerously low blood pressure. Before taking erectile dysfunction medication, you should tell your doctor:

  • About any allergies you may have to medications

  • About any prescription drugs you are currently taking

  • If you have a surgery scheduled 

  • If you currently take alpha-blockers for blood pressure or prostate issue. 

You should always read and understand your prescription.


While side-effects are uncommon, they can still happen and it is important that you know how to identify them. You may experience: 

  • Back pain 

  • Hearing loss 

  • Upset stomach or heartburn 

Warning: If you have an erection lasting up to four hours without any sexual excitement, you should seek medical attention.
