Do not start, stop, or change the dosage of any medicines without your doctor's approval.Other medications can affect the removal of ergotamine from your body, which may affect how ergotamine works. Examples include boceprevir, mifepristone, telaprevir, HIV NNRTIs (such as delavirdine, efavirenz), a certain combination HIV medication (elvitegravir/cobicistat/emtricitabine/tenofovir), certain antidepressants (such as nefazodone, SSRIs such as fluoxetine/paroxetine/fluvoxamine), among others.If you also take "triptan" migraine drugs (e.g., sumatriptan, rizatriptan), you will need to separate your "triptan" dose from your dose of this medication to reduce the risk of serious side effects. Ask your doctor how long you should wait between your doses of these drugs.Check the labels on all your medicines (e.g., cough-and-cold products, diet aids, other migraine medications) because they may contain caffeine or other ingredients that could increase your heart rate or blood pressure. Also keep in mind that certain beverages (e.g., coffee, colas, tea) contain caffeine. Ask your pharmacist about the safe use of those products.This medication may interfere with certain medical/laboratory tests (including dipyridamole-thallium imaging tests, urine catecholamine levels, urine 5-HIAA levels), possibly causing false test results.
