- This medication has rarely caused a serious lack of blood flow to the arms/hands, or to the feet, or to the brain, which could cause a stroke. The risk is increased when this medication is taken with other drugs that can affect the removal of ergotamine from your body. Examples include boceprevir, mifepristone, telaprevir, telithromycin, certain antidepressants (such as nefazodone), azole antifungals (such as ketoconazole, itraconazole), cobicistat, macrolide antibiotics (such as clarithromycin, erythromycin, troleandomycin), HIV protease inhibitors (such as ritonavir, nelfinavir, indinavir), HIV NNRTIs (such as delavirdine), SSRIs (such as fluoxetine, paroxetine, fluvoxamine), among others.
