Hi All, I was wondering what people's experience with using IV DHE has been in regards to the utility of this medication for: 1. Medication overuse headache. 2. Status migraine. 3. Chronic migraine / i.e. breaking the cycle of headache. Specifically, using DHE in the ambulatory / outpatient setting is what I had in mind. I practice in Canada, and thus inpatient Tx is not a possibility. Any insight would be appreciated. Do your clinical experiences reflect the studies?
