Prescription Opiates

4 Months of High-Dose Opiate Use Ups Erectile Dysfunction Risk by 50%

Here’s one very compelling reason to quit opiates sooner rather than later.

Need a good reason to seek treatment for an opiate addiction?

Well you might find the inspiration you’ve been looking for in a new study out of the Kaiser Center for Health Research that links just three to four months of high dose opiate use with a significantly increased likelihood of erectile dysfunction…50% higher!!!

The Study

The researchers examined the medical records of 11 327 men with back pain who were enrolled with Kaiser Permanente in Portland Oregon. Many of these men received prescriptions for opiates to control their pain.

The study looked to investigate:

  1. Did getting prescribed opiates increase a man’s likelihood to request erectile dysfunction (ED) medication, such as sildenafil, tadalafil or testosterone replacement within 6 months?
  2. What factors influenced an increased likelihood to require ED medication?

The Results

Over a 12 month time period around seeing a doctor for back pain

  • 6.7% of men not prescribed opiates received a prescription for an ED medication
  • 12.5% of men prescribed low dose opiates for 120 days or longer (or 90 days or longer with 10 or more prescription refills) received a prescription for an ED medication
  • 19.3% of men on higher doses of opiates (120 morphine equivalents or greater per day) for 120 days or longer (or 90 days or longer with 10 or more prescription refills) received a prescription for an ED medication
  • Having depression and taking sedative hypnotics, like benzodiazepines, also increased a man’s likelihood of requiring an ED medication
  • Surprisingly, neither obesity nor smoking were associated with an increased likelihood to require an ED medication


The study authors recommend that primary care physicians weigh the risks of sexual dysfunction when making prescribing decisions and that patients receive information about these sexual risks and about possible alternative therapies, such as cognitive behavioral therapy and physiotherapy exercises.

Opiates are known to decrease testosterone levels. The study authors suggest that this is the most probable explanation for their negative influence on erectile functioning.
