Regular use of opioid prescription painkillers for treating back pain in men could increase the risk of them suffering from erectile dysfunction.

The researchers found that nearly 1 in five patients, or 19 percent, who had were prescribed high-dose opioids for at least four months also received prescriptions for testosterone replacement or medications for ED compared to just 7 percent who did not take opioids but received ED prescriptions.
“Men who take opioid pain medications for an extended period of time have the highest risk of ED. This doesn't mean that these medications cause ED, but the association is something patients and clinicians should be aware of when deciding if opioids should be used to treat back pain”, Deyo said.
