What Kind of Medicine Is This?

This medicine is called ergotamine. It usually comes as a tiny pill that you place under your tongue to dissolve, which doctors call a sublingual tablet. It is specifically made to help you control and stop severe migraine headaches once they begin.

To put it simply, ergotamine does two main things inside your brain. First, it blocks the pain signals that cause your migraine misery. Second, when a migraine happens, the blood vessels in your head stretch out and swell up. Ergotamine helps those swollen blood vessels shrink back down to normal size.

This medicine belongs to a group of drugs known as ergot alkaloids. You might see it sold under the brand name Ergomar.

Remember this very important rule: This medicine is NOT used to prevent migraines before they start. You only take it after your headache begins or right when you notice early migraine warning signs. Do not take it in advance hoping to stop a headache that has not started yet.

Sometimes your doctor may prescribe this medicine for other health needs. If you have any questions about your prescription, always ask your doctor or pharmacist for clear guidance.

What to Tell Your Doctor Before Taking This Medicine

Before you start taking ergotamine, you must share your complete health history with your doctor. If you have any of the following medical conditions, tell your doctor right away without hiding anything so they can decide if this medicine is safe for you:

  • Do you have chest pain or trouble breathing?
  • Do you have heart disease or blood vessel disease?
  • Do you have high blood pressure?
  • Do you have an active infection or inflammation in your body?
  • Do you have kidney disease?
  • Do you have liver disease?
  • Do you have poor blood circulation, such as cold or numb fingers and toes?
  • Do you smoke cigarettes or use tobacco products, which raise your risk of heart problems?
  • Have you ever had an allergic reaction to ergotamine, other medicines, foods, dyes, or preservatives?
  • Are you currently pregnant or trying to get pregnant?
  • Are you breastfeeding a baby?

If any of these health situations apply to you, please let your doctor know right away.

How to Use This Medicine

Using ergotamine correctly is very important for your safety and comfort. Follow these simple directions carefully:

  • How to take it: Take this medicine by mouth. Place the tablet directly under your tongue and let it stay there until it dissolves completely.
  • The most important rule: Do not chew or swallow the tablet. Let it melt under your tongue so your body can absorb the medicine properly.
  • Follow your prescription: Follow the exact instructions written on your prescription label by your doctor or pharmacist.
  • Best timing: For the best results, take the tablet the moment your migraine headache starts, or right when you feel warning signs like an aura. Do not wait. Taking it early gives you the best relief.
  • Do not overuse: This is not a daily medicine. Never take more than the dose your doctor prescribed, and do not take it more times per day than instructed.
  • Giving it to children: Talk to your doctor before giving this medicine to children, as special care is needed. Never give it to a child without direct medical advice.
  • In case of overdose: If you think you took too much of this medicine, call your local poison control center or go to the nearest hospital emergency room right away. In the US or Canada, call 911; in the UK, call 999.
  • Do not share: This medicine was prescribed just for you. Never share it with a friend or family member, even if they have migraines too. Every person needs different medical care.

What to Do If You Miss a Dose

Missing a dose is usually not an issue with this medicine. As mentioned before, you do not take ergotamine on a regular daily schedule. You only use it when a migraine headache strikes.

What Other Things Can Interact with This Medicine?

Some medicines can cause dangerous problems if you take them together with ergotamine. Other substances can also change how well this medicine works in your body.

Never take ergotamine with any of the following medicines:

  • Bromocriptine .
  • Ceritinib .
  • Certain antibiotics like clarithromycin and erythromycin .
  • Certain antiviral drugs used for HIV or hepatitis .
  • Certain medicines for high blood pressure, heart disease, or irregular heartbeats .

  • Other migraine medicines known as triptans, such as almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, and zolmitriptan .
  • Cocaine .
  • Idelalisib .

  • Levoketoconazole .
  • Lonafarnib .
  • Mifepristone .

  • Clotrimazole (an antifungal medicine) .
  • Fluconazole (an antifungal medicine) .
  • Grapefruit juice: This is very important. Drinking grapefruit juice while taking ergotamine can increase your risk of bad side effects.

Things to Watch Out for While Using This Medicine

While using ergotamine, keep a close eye on a few other important details regarding your daily routine and body reactions:

  • If you get no relief: If this medicine does not help your migraine pain, or if your headaches change and feel different than usual, talk to your healthcare team. You may need to try a different medicine or treatment plan.
  • Dizziness and drowsiness: This medicine can make you feel sleepy or dizzy. Until you know how ergotamine affects you, do not drive cars, use heavy machinery, or do anything that requires sharp mental focus. To prevent dizzy spells or fainting, avoid standing up or sitting down too quickly; move slowly. Older adults should be especially careful. Drinking alcohol makes dizziness, sleepiness, and flushing much worse, so avoid alcohol completely while taking this medicine.
  • Blood circulation: Ergotamine can slow down blood flow to your skin, fingers, and toes. Because of this, you might feel much more sensitive to cold weather. Your hands and feet might feel cold, numb, or tingly. Older adults are more likely to experience this effect. Dress warmly in cold weather and avoid staying outside in the cold for long periods.
  • Medicine overuse headaches: This is very important. If you take migraine pain medicines (including ergotamine and other painkillers) on 10 or more days per month, your headaches can actually get worse instead of better. Doctors call this a medicine overuse headache. Keeping a headache diary to track your headache days and medicine amounts is very helpful. If your migraine attacks happen more often or change in pattern, call your doctor right away.

Get emergency medical help right away (Call 911 in the US/Canada or 999 in the UK, or go to the nearest Emergency Room) if you experience any of these dangerous red flags:

❓ FAQ

Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

Can I swallow ergotamine sublingual tablets like a regular pill?

No, you should never swallow or chew ergotamine sublingual tablets. You must place the tablet under your tongue and let it dissolve completely so your body can absorb the medicine properly through the lining of your mouth.

Should I take ergotamine every day to prevent migraines?

No, ergotamine is not a daily preventive medicine. You only take it when a migraine headache begins or when you notice early warning signs. Taking it daily will not prevent migraines and can lead to medicine overuse headaches.

Why is grapefruit juice dangerous with ergotamine?

Grapefruit juice blocks how your body breaks down ergotamine. This causes too much medicine to build up in your bloodstream, which can raise your risk of dangerous side effects and poor blood circulation.

What should I do if my migraine does not go away after taking a tablet?

If your migraine pain does not improve, do not take extra medicine on your own. Call your doctor right away for guidance, as you should never exceed your prescribed dose.

Can I share my ergotamine tablets with a family member who has migraines?

Never share your prescription medicine with anyone else. Ergotamine can be very dangerous for people with certain heart or blood pressure conditions that they might not know they have.
