The List of Prescription Drugs That May Cause Erectile Dysfunction

Erectile dysfunction (ED) is a common side effect of a number of prescription drugs.

While these medications may treat a disease or condition, in doing so they can affect a man’s hormones, nerves or blood circulation. The result may be ED or an increase in the risk of ED.

If you have ED and think that it may be a result of the medication you are using, do not stop taking the medication. If the problem persists, contact your doctor and he or she may be able to prescribe a different medication. Common medications that may list ED as a potential side effect include:

      • Diuretics (pills that cause an increase in urine flow).
      • Antihypertensives (medication for high blood pressure).
      • Antihistamines.
      • Antidepressants.
      • Parkinson’s disease drugs.
      • Antiarrhythmics (medication for irregular heart action).
      • Tranquilizers.
      • Muscle relaxants.
      • Non-steroidal anti-inflammatory drugs.
      • Histamine H2-receptor antagonists.
      • Hormones.
      • Chemotherapy medications.
      • Prostate cancer drugs.
      • Anti-seizure medications.

Drugs that may cause erection problems

Many medicines and recreational drugs can affect a man’s sexual arousal and sexual performance. What causes erection problems in one man may not affect another man.

Talk to your health care provider if you think that a drug is having a negative effect on your sexual performance. Never stop taking any medicine without first talking to your provider. Some medicines may lead to life-threatening reactions if you do not take care when stopping or changing them.
