Alan Rapoport, MD, a clinical professor of neurology at the David Geffen School of Medicine at University of California, Los Angeles, noted a number of limitations with the study. “It wasn’t a unified population of patients,” he said, “which makes it a little harder to say this medicine worked — worked on whom?” The lack of a treatment regimen — the varied dosing and treatment durations, along with the different withdrawal approaches — are further limitations, Dr. Rapoport said.
Nonetheless, the study is an important addition to the evidence on how to manage medication withdrawal in MOH, said Dr. Rapoport, a past president of the International Headache Society and founder and director emeritus of the New England Center for Headache in Stamford, Connecticut, who has a keen interest in MOH research.
“I think this shows to some extent, although it doesn’t prove it because it’s a whole mixture of patients who were all treated differently by different doctors, but when you put them all together the patients who took steroids did better than the patients who did not,” he said. “The study authors did the best they could with the information they had.”
He termed the study “well-done by well-known authors in South Korea.” As medications such as CGRP receptor antagonists and monoclonal antibodies that target CGRP and its receptors become more available, MOH patients “may not need actual detoxification or steroids in their treatment,” Dr. Rapoport said.
