Dihydroergotamine has also been shown to be an inhibitor of cytochrome P450 3A catalyzed reactions and rare reports of ergotism have been obtained from patients treated with dihydroergotamine and macrolide antibiotics (e.g., troleandomycin, clarithromycin, erythromycin), and in patients treated with dihydroergotamine and protease inhibitors (e.g., ritonavir), presumably due to inhibition of cytochrome P450 3A metabolism of ergotamine (see CONTRAINDICATIONS)
So be careful not to rely on them long term
Secondly, the only first-line therapy evaluated was diet modification
On that matter, you should carefully follow your prescribing physicians instructions
Milligrams = (Units / 100) x Concentration in mg per ml Example: you drew 35 units from a 20mg/ml vial
