A recent retrospective review study that was presented at the Anesthesiology Annual Meeting in Boston found that ketamine effective in treating migraines.
The study looked at 61 men who "have been afflicted by the neural pain often enough, or intensely enough, over the past three years that they've been admitted to hospitals," IFLScience.com reported. "No other treatment proved effective, and until now, they were doomed to live a migraine-riddled life."
These patients were given small doses of ketamine for up to a week and this treatment regimen was found effective in 3 out of the 4 participants. Patients reported brief hallucinations and very vivid dreams.
This study only looked at information concerning males, however it's believed it's likely the same effect would be observed in women.
