Understanding Erectile Dysfunction Medications (cont.)

Prostaglandins

Prostaglandins include alprostadil (Caverject, Edex, Muse Pellet).

  • How prostaglandins work: These drugs work by enhancing blood flow in the penis, thereby causing erection.

  • Who should not use these medications: Persons with allergy to alprostadil should not take them, nor should those with hyaline membrane disease, respiratory distress syndrome, penile implants or an abnormally formed penis, or conditions resulting in long-lasting erections (for example, sickle cell anemia or trait, leukemia, or multiple myeloma).

  • Use: Prostaglandins are administered as either an injection into the penis or as a pellet inserted into it (via the urethral opening at the end of the penis).

  • Drug or food interactions: No drug or food interactions are currently known.

  • Side effects: Contact a doctor if an erection lasts more than 4 hours. Prostaglandins may cause headache, decreased blood pressure, or dizziness. Caution is warranted in individuals with heart disease that may be aggravated by decreased blood pressure or dizziness.
