WEDNESDAY, May 15 (HealthDay News) -- If you're a man, the pain-killing medications known as opioids may do more than relieve pain -- they may also put a damper on your sex life.
A new study found that men who were prescribed medications for erectile dysfunction or low testosterone levels were more likely to be taking opioid (narcotic) medications for chronic back pain.
"People who have persistent pain problems need to know that a potential side effect of long-term opioid use may be erectile dysfunction," said lead study author Dr. Richard Deyo, a clinical investigator for the Kaiser Permanente Center for Health Research in Portland, Ore. "This is not a well-known potential side effect among patients, and it should be considered when thinking about treatment."
Deyo also noted, however, that "the nature of this study as an observational study limits our ability to make a causal [cause-and-effect] inference. Opioid use and erectile dysfunction seem to go together, but we have to be cautious about saying one causes the other."
Results of the study were published in the May issue of the journal Spine.
More than 4 million people use opioids on a regular basis, Deyo said. Commonly prescribed opioids include hydrocodone, oxycodone and morphine. In this study, use of opioids was considered long-term if patients used them for more than 120 days, or more than 90 days if more than 10 prescriptions were filled for the drugs.
The study included data on about 11,000 men who had back pain. In that group, more than 900 received medications for erectile dysfunction or testosterone replacement. Those who were given prescriptions for erectile dysfunction medications or testosterone were older than those who didn't get such prescriptions. They also were more likely to have depression and other health conditions.
