Abstract
We report a case of refractory back pain successfully treated with transdermal fentanyl patch. A 44-year-old woman with low back pain resulting from L3/4 disc degeneration was treated with 1 mg of transdermal fentanyl patch, which decreased pain from 9 to 3 on the numerical rating scale. The patient underwent spinal surgery of L3/4 fixation 3 months later, and the transdermal fentanyl patch was stopped. A transdermal fentanyl patch may be useful for patients suffering from chronic back pain by disc degeneration.
