Feedback:
Patients being treated with voriconazole or posaconazole should be cautioned about the risk of ergotism if they combine this drug with ergot, an herb frequently used to treat migraine headache and menstrual problems. If the patient is using voriconazole, it should be suggested that ergot not be used until the antifungal therapy is finished. The other options do not have a known drug interaction with ergot.
