This medication can harm an unborn baby or a nursing baby. Do not use caffeine and ergotamine if you are pregnant or breast-feeding.
Do not use this medication if you are allergic to caffeine and ergotamine or other ergot medicines, or if you have a history of heart disease, angina (chest pain), blood circulation problems, history of a heart attack or stroke, coronary artery disease, uncontrolled high blood pressure, severe liver or kidney disease, or a serious infection.
Using certain medications together with caffeine and ergotamine can cause even greater decreases in blood flow than caffeine and ergotamine used alone. A severe decrease in blood flow to the brain and other parts of the body can lead to dangerous side effects. Tell your doctor about all other medications you are using, especially antibiotics, antidepressants, heart or blood pressure medications, or medicines to treat HIV or AIDS.
Also tell your doctor about all of your medical conditions, especially breathing problems, high blood pressure, liver or kidney disease, or risk factors for coronary artery disease (diabetes, high blood pressure or cholesterol, menopause or hysterectomy, smoking, taking birth control pills, being overweight, having a family history of coronary artery disease, or being a man older than 40).
This medication will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Never use more than your prescribed dose of caffeine and ergotamine. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks. An overdose of caffeine and ergotamine can be fatal.
