Common antidepressants interact with opioid med to lessen pain relief

Common antidepressants interact with the opioid pain medication tramadol to make it less effective for pain relief, according to a study from University Hospitals (UH). These findings have important implications for the opioid epidemic, suggesting that some patients suspected of drug-seeking may, in fact, be under-medicated and just are seeking more effective pain relief. They also could help explain why some people exceed the prescribed dose of tramadol, increasing their risk of addiction.

The study was published in the journal Pharmacotherapy.

Researchers reviewed the medication records of 152 patients at UH Cleveland Medical Center and UH Geauga Medical Center who received scheduled tramadol for at least 24 hours. All participants in the study were admitted as inpatients or observation status. Those patients who also were taking the antidepressants Prozac (fluoxetine), Paxil (paroxetine) or Wellbutrin (bupropion) required three times more pain medication per day to control “breakthrough” pain throughout the day, when compared with patients not taking those antidepressants.
