What is Cafergot? Common use and how it works
Cafergot combines ergotamine tartrate (a potent vasoconstrictor) with caffeine (which enhances absorption and augments vasoconstriction) to abort acute migraine attacks. Migraines involve trigeminal activation and dilation of cranial blood vessels; ergotamine targets serotonin receptors and adrenergic pathways to narrow those vessels, which can reduce pulsating pain and photophobia/phonophobia when taken early in the attack. Cafergot is intended for acute treatment, not for prevention, and is generally reserved for adults who have specific reasons to avoid or who do not respond to first-line options such as triptans or certain NSAIDs.
Because ergot derivatives carry vascular risks, clinicians select Cafergot for carefully screened patients and emphasize early use at the prodrome or headache onset for best effect. It is not appropriate for hemiplegic or basilar-type migraine, and it should not be used in children, during pregnancy, or while breastfeeding. Some specialists may consider ergotamine for select cluster headache patients, but modern guidelines often prefer alternatives; discuss your diagnosis and goals with a healthcare professional.
Cafergot dosage and direction
For adults using Cafergot tablets (ergotamine tartrate 1 mg + caffeine 100 mg each): at the first sign of headache or aura, take 2 tablets. If needed, take 1 additional tablet every 30 minutes until relief, not to exceed 6 tablets in any 24-hour period (6 mg ergotamine) or 10 tablets in one week (10 mg ergotamine). Use Cafergot for as few attacks as possible and limit to no more than 2 treatment days per week to reduce the risk of medication-overuse headache and ergot-related toxicity. Do not use it for chronic daily headaches or as prophylaxis.
Swallow tablets with water; you may take them with food if stomach upset occurs. If vomiting prevents oral dosing, speak with your clinician about alternatives; do not improvise dosing forms. Never combine Cafergot with a triptan within 24 hours (before or after). If you reach the daily or weekly maximum without relief, stop and seek medical advice. Keep a headache diary (timing, dose, triggers, response) to help your clinician refine your treatment plan. Always adhere to the specific instructions on your prescription label.
Precautions before using Cafergot
Because ergotamine can markedly constrict blood vessels, patients with cardiovascular risk factors require careful evaluation. Tell your clinician if you smoke, have high blood pressure, high cholesterol, diabetes, are over age 40, or have a family history of early heart disease or stroke. Report any history of Raynaud’s phenomenon, peripheral vascular disease, or circulation problems. Cafergot should not be used more frequently than prescribed; overuse can lead to medication-overuse headache, rebound pain, and ergotism.
Avoid Cafergot during pregnancy and while breastfeeding. Inform your clinician about liver or kidney problems, infection/sepsis, recent surgery, or severe dehydration. Limit other caffeine sources to reduce jitteriness and palpitations. Stop use and seek urgent care if you notice chest pain, shortness of breath, severe abdominal pain, or cold/blue fingers or toes.
Contraindications: who should not use Cafergot
Do not use Cafergot if you have any of the following: coronary artery disease, history of heart attack or stroke/TIA, uncontrolled hypertension, peripheral vascular disease, severe Raynaud’s phenomenon, ischemic bowel disease, severe liver or kidney impairment, sepsis/serious systemic infection, or known hypersensitivity to ergot alkaloids. Cafergot is contraindicated during pregnancy (risk of decreased uterine blood flow and fetal harm) and should not be used while breastfeeding due to potential vasoconstriction and reduced milk production.
Absolute contraindication also applies if you are taking potent CYP3A4 inhibitors such as macrolide antibiotics (for example, erythromycin or clarithromycin), certain antifungals (ketoconazole, itraconazole, voriconazole), or HIV protease inhibitors (ritonavir and others), because dangerous, prolonged vasoconstriction and ischemia can occur.
Cafergot side effects: common and serious
Common effects can include nausea, vomiting, abdominal discomfort, dizziness, flushing, mild tingling, and fatigue. The caffeine component may cause restlessness, tremor, irritability, insomnia, or palpitations, especially if combined with coffee, energy drinks, or other stimulants. Taking with food may help stomach upset. Many patients tolerate occasional use, but side effects are more likely at higher doses and with frequent dosing.
Serious adverse reactions require immediate medical attention: chest pain or pressure, shortness of breath, severe or one-sided weakness, vision changes, slurred speech, fainting, severe abdominal pain, sudden decrease in urine output, or signs of limb ischemia (cold, painful, numb, pale, or blue fingers/toes with weak or absent pulses). Prolonged or excessive dosing can cause ergotism—marked vasospasm leading to tissue ischemia and, rarely, gangrene. Stop Cafergot and seek emergency care if you experience any symptoms suggestive of reduced blood flow or neurological deficit.
Cafergot interactions: what to avoid
Dangerous increases in ergotamine levels occur with strong CYP3A4 inhibitors. Never take Cafergot with macrolide antibiotics (erythromycin, clarithromycin), azole antifungals (ketoconazole, itraconazole, voriconazole, posaconazole), HIV protease inhibitors or cobicistat-boosted regimens, or certain hepatitis C antivirals with strong CYP3A4 inhibition. Combining these drugs can precipitate severe vasoconstriction, ischemia, and life-threatening complications. Also avoid Cafergot within 24 hours of any triptan (sumatriptan, rizatriptan, zolmitriptan, etc.), both before and after dosing, due to additive vasoconstriction.
Use caution or avoid with other vasoconstrictors and stimulants, including nicotine (cigarettes, vaping), decongestants containing pseudoephedrine or phenylephrine, and certain beta-blockers (for example, propranolol) that can potentiate peripheral vasospasm when combined with ergotamine. Grapefruit or grapefruit juice may raise ergotamine concentrations; avoid during Cafergot therapy. Moderate CYP3A4 inhibitors (for example, verapamil, diltiazem) can increase exposure; your clinician may advise against co-use. Herbal and over-the-counter products can interact unpredictably—always provide a full medication list to your pharmacist or prescriber and verify safety before starting or stopping any drug.
Missed dose
Cafergot is taken as needed at headache onset, not on a fixed schedule. If you delayed the first dose, take it as soon as you recognize migraine symptoms, then follow the labeled spacing and maximums. Do not “double up” to compensate, and do not exceed the daily or weekly limits. If your symptoms have resolved, do not take Cafergot “just in case.”
Overdose: signs and actions
Overdose or excessive cumulative use can cause severe nausea/vomiting, muscle pain, tingling or numbness, cold or blue extremities, severe abdominal pain, chest pain, confusion, agitation, or seizures. These may signal ergot toxicity and critical reductions in blood flow. If you suspect overdose or severe reaction, call emergency services immediately and contact Poison Control (1-800-222-1222 in the U.S.). Do not drive yourself. Bring your medication container to the hospital if possible to assist clinicians. Future use should be reassessed with your prescribing professional.
Storage and handling
Store Cafergot at room temperature (68–77°F or 20–25°C) in a dry place away from heat, light, and moisture. Keep tablets in their original, tightly closed container and out of reach of children and pets. Do not use beyond the expiration date. Dispose of unused or expired medicine according to pharmacy or local guidelines; do not flush unless instructed.
