Abstract: | We reviewed data on 171 patients with refractory headache treated by continuous intravenous dihydroergotamine mesylate (IV DHE 45 ÒÒ ) and repetitive IV DHE and compared the efficacy of continuous IV DHE to repetitive IV DHE. One hundred (58.5%) patients had refractory chronic daily headache. Seventy-one (42%) had drug rebound headache. One hundred thirty-eight (81%) had refractory migraine without aura, and 28 (16%) had migraine with aura. Treatment consisted of either continuous IV DHE by infusion pump or repetitive IV DHE and withdrawal of excessively used analgesics, analgesic narcotics, ergotamines, or benzodiazepines. Eighty-nine (92.5%) patients treated with continuous IV DHE became headache-free; the majority, 62 (64.5%), within 3 days. Sixty-five (86.5%) patients treated by repetitive IV DHE became headache-free, 50 (66.5%) within three days. The average hospital stay for both treatment groups was 4 days. Twelve (12.5%) of the continuous group and 12 (16%) of the repetitive group were headache-free within 24 hours. The average length of time to become headache-free was similar for the two groups, 3.06 days for continuous IV DHE and 2.94 days for repetitive IV DHE. The most common side effect was nausea, followed by diarrhea, vomiting, and leg cramps. We conclude that DHE can be accurately and easily administered by continuous IV infusion pump, and that continuous IV DHE is a safe and efficacious mode of treatment producing results similar to repetitive IV DHE. |
