Cafergot (Generic Ergotamine-Caffeine): Complete Medication Guide
Key Takeaways
Cafergot is a combination medication that treats acute migraine headaches by narrowing blood vessels in the brain.
It works best when taken at the first sign of a migraine, before pain becomes severe.
Common side effects include nausea, vomiting, and tingling in the fingers or toes.
Serious side effects are rare but can include chest pain, rapid heartbeat, and circulation problems.
This medication requires careful dosing and should not be used more than twice a week.
Cafergot (Generic Ergotamine-Caffeine) Overview
Cafergot is a combination medication containing ergotamine and caffeine, used to treat acute migraine headaches. Ergotamine belongs to a class of drugs called ergot alkaloids, which work by narrowing blood vessels around the brain and reducing substances in the body that can trigger pain, nausea, and sensitivity to light and sound. Caffeine helps the body absorb ergotamine more effectively, making the medication work faster and stronger.
This medication is specifically designed for acute migraine relief—meaning you take it when a migraine starts, not as a daily preventive medication. When taken early during a migraine attack, Cafergot can help stop the headache from getting worse and may provide relief within 30 to 60 minutes. As a generic alternative to brand-name drugs, the generic ergotamine-caffeine combination offers the same active ingredients at a lower cost, making migraine treatment more affordable for many people.
Cafergot is available in tablet and suppository forms. Many patients prefer the tablet form for convenience, though the suppository form can be useful if nausea prevents swallowing pills during a migraine attack.

Side Effects
Cafergot is generally tolerated well by most people, but like all medications, it may cause side effects in some patients. Side effects are usually mild and temporary, especially if you take the medication as directed at the first sign of a migraine.
Common Side Effects
Nausea and vomiting – The most frequent side effects, often related to the migraine itself rather than the medication. Taking Cafergot early in the attack may help reduce these symptoms.
Tingling or numbness in fingers and toes – This vasoconstriction-related side effect is usually mild and goes away after the medication wears off.
Dizziness – Some people feel lightheaded or dizzy after taking Cafergot. Resting in a quiet, dark room may help.
Muscle aches or weakness – Ergotamine can cause temporary muscle discomfort in some patients.
Constipation – Less common but possible, especially with regular use. Staying hydrated and eating fiber-rich foods may help.
Serious Side Effects
Chest pain or tightness – This could indicate a serious heart or circulation problem and requires immediate medical attention.
Severe leg or arm pain – May signal reduced blood flow to your limbs, a condition called peripheral vasoconstriction.
Rapid or pounding heartbeat – Unusual heart rhythm changes should be evaluated by a doctor promptly.
Signs of stroke – Including severe headache, vision changes, weakness on one side of the body, or difficulty speaking.
Gangrene or tissue damage – Extremely rare, but can occur with overuse or in people with circulation problems.
When to Seek Medical Attention
Contact your doctor right away if you experience chest pain, severe leg or arm pain, shortness of breath, or signs of a stroke after taking Cafergot. If you regularly experience side effects that interfere with your daily life, talk with your healthcare provider about whether this medication is the best choice for you. Some people may benefit from alternative migraine treatments or preventive therapies.

Important: Never stop taking Cafergot without talking to your doctor, especially if you use it regularly. If you miss a dose, skip the missed dose and take your next dose only when you have another migraine. Do not use Cafergot more than twice per week, as overuse can lead to medication overuse headache, a condition where frequent use of pain relief drugs actually triggers more headaches. Keep track of how often you use Cafergot to make sure you stay within safe limits.
Drug Interactions
Cafergot can interact with several medications and substances, potentially reducing its effectiveness or increasing the risk of side effects. Always tell your doctor about all medications, supplements, and herbal products you take before starting Cafergot. Some interactions can be serious, so open communication with your healthcare provider is essential.
Sumatriptan and Other Triptans
Combining Cafergot with triptan migraine medications (like sumatriptan or rizatriptan) may cause dangerous blood vessel constriction. Space these medications apart, and use only one type of migraine medication per attack as directed by your doctor.
SSRIs and SNRIs (Antidepressants)
Antidepressants like sertraline, paroxetine, and venlafaxine may increase serotonin levels when combined with ergotamine, raising the risk of serotonin syndrome. Symptoms include agitation, rapid heartbeat, and muscle rigidity.
Macrolide Antibiotics
Medications like erythromycin and azithromycin can slow the breakdown of ergotamine in your body, leading to higher drug levels and increased risk of ergot toxicity or dangerous blood vessel constriction.
Protease Inhibitors (HIV Medications)
Protease inhibitors used to treat HIV can significantly increase ergotamine levels in your bloodstream, raising the risk of serious side effects including severe blood vessel narrowing and heart problems.
Vasoconstrictors and Decongestants
Over-the-counter decongestants like pseudoephedrine, when combined with Cafergot, may cause dangerous increases in blood pressure or excessive blood vessel constriction.
Hormonal Contraceptives
Birth control pills may increase the risk of blood clots and heart problems when used with ergotamine-containing medications. Discuss safer birth control options with your doctor if you use Cafergot regularly.

Frequently Asked Questions
Get answers to common questions about Cafergot (Generic Ergotamine-Caffeine).
Most people experience relief within 30 to 60 minutes of taking Cafergot, especially if taken at the very first sign of a migraine. Taking it early—before pain becomes severe—gives you the best chance of stopping the migraine from getting worse. Waiting until the migraine is in full force may reduce how effective the medication is.
No. Cafergot should only be used to treat acute migraine attacks as they happen, not for daily prevention. Using it more than twice per week can lead to medication overuse headache, where frequent use of pain relievers actually triggers more headaches. If you have frequent migraines, ask your doctor about preventive medications designed for daily use.
Yes. Understanding the differences between generic and brand-name drugs shows that generic ergotamine-caffeine contains the same active ingredients in the same doses as the brand-name Cafergot. The FDA requires generic drugs to meet strict quality and effectiveness standards, making them equally safe and effective while costing significantly less.
If Cafergot does not provide relief within 60 minutes or if your migraines are getting worse despite treatment, contact your doctor. You may benefit from a different migraine medication, such as a triptan, or from preventive therapy if migraines occur frequently. Never take additional doses beyond what your doctor recommends.
Yes. After taking Cafergot, avoid driving or operating machinery until you feel completely alert, as dizziness and lightheadedness may occur. Rest in a quiet, dark room if possible, as this helps with both migraine recovery and medication tolerability. Avoid sudden position changes, which may increase dizziness, and stay hydrated to help your body process the medication safely.
The Bottom Line
Cafergot (generic ergotamine-caffeine) is an effective acute migraine treatment that works by narrowing blood vessels in the brain to stop headache pain. When taken at the first sign of a migraine, it may provide relief within 30 to 60 minutes.
