Medication overuse headaches

Diagnosis

Your health care provider can usually diagnose medication overuse headaches based on your history of headaches and regular use of medicine. Testing usually isn't necessary.

Treatment

To break the cycle of medication overuse headaches, you'll need to restrict pain medicine. Your health care provider may recommend stopping the medicine right away or gradually reducing the dose.

Breaking the cycle

When you stop your medicine, expect headaches to get worse before they get better. You can develop a dependence on some medicines that result in medication overuse headaches. Withdrawal symptoms may include:

• Nervousness.
• Restlessness.
• Nausea.
• Vomiting.
• Insomnia.
• Constipation.

These symptoms generally last 2 to 10 days. But they can persist for several weeks.

Your health care provider may prescribe treatments to help with headache pain and the side effects of medicine withdrawal. This is known as bridge or transitional therapy. Treatments may include nonsteroidal anti-inflammatory drugs, corticosteroids or nerve blocks. Your provider also might recommend the ergot dihydroergotamine given through a vein.

There's debate over how much benefit bridge therapy may offer. There's also debate about whether one treatment works better than others. Withdrawal headaches tend to improve in less than a week.

Hospitalization

Sometimes it's best to be in a controlled environment when you stop taking pain medicine. A short hospital stay may be recommended if you:

• Have other conditions, such as depression or anxiety.
• Are taking high doses of drugs that contain opiates or the sedative butalbital.
• Are using substances such as tranquilizers, opioids or barbiturates.

Preventive medications

Preventive medicines may help you break the cycle of medication overuse headaches. Work with your health care provider to avoid relapsing and to find a safer way to manage your headaches. During or after withdrawal, your provider may prescribe a daily preventive medicine such as:

• An anticonvulsant such as topiramate (Topamax, Qudexy XR, others).
• A tricyclic antidepressant such as amitriptyline or nortriptyline (Pamelor).
• A beta blocker such as propranolol (Inderal LA, Innopran XL, Hemangeol).
• A calcium channel blocker such as verapamil (Calan SR, Verelan, Verelan PM).

If you have a history of migraine, your health care provider might suggest an injection of a CGRP monoclonal antibody such as erenumab (Aimovig), galcanezumab (Emgality), fremanezumab (Ajovy) or eptinezumab (Vyepti). Erenumab, galcanezumab and fremanezumab are monthly injections. Eptinezumab is given every three months with an IV infusion.

These medicines can help control your pain without risking medication overuse headaches. You may be able to take a medicine specifically meant for pain during future headaches. But be sure to take them exactly as prescribed.

Injections

Injections of onabotulinumtoxinA (Botox) may help reduce the number of headaches you have each month. They also may make headaches less severe.

Cognitive behavioral therapy (CBT)

This talk therapy teaches ways to cope with headaches. In CBT, you also work on healthy lifestyle habits and keep a headache diary.

Alternative medicine

For many people, complementary or alternative therapies offer relief from headache pain. However, not all of these therapies have been studied as headache treatments. For some therapies, further research is needed. Discuss the risks and benefits of complementary therapy with your health care provider.

Possible therapies include:

• Acupuncture. This ancient technique uses fine needles to promote the release of natural painkillers and other chemicals in the central nervous system. This therapy may ease headaches.
• Biofeedback. Biofeedback teaches you to control certain body responses that help reduce pain. During biofeedback, you're connected to devices that monitor you. They give you feedback on body functions such as muscle tension, heart rate and blood pressure. You then learn how to reduce muscle tension and slow your heart rate and breathing. This helps you relax, which may help you cope with pain.
• Herbs, vitamins and minerals. Some dietary supplements seem to help prevent or treat certain types of headaches. But there's little scientific support for these claims. They include magnesium, feverfew, coenzyme Q10 and riboflavin, also known as vitamin B2. If you're considering using supplements, check with your health care provider. Some supplements may interfere with other medicines you take. Or they may have other harmful effects.

Coping and support

You may find it helpful to talk to other people who've been through the same experience you're having. Ask your health care provider if there are support groups in your area. Or contact the National Headache Foundation at www.headaches.org or 888-643-5552.

Preparing for your appointment

You're likely to start by seeing your primary care provider. You may then be referred to a doctor who specializes in nervous system disorders, known as a neurologist.

Here's some information to help you get ready for your appointment.

What you can do

• Keep a headache diary. Write down your symptoms, even those that seem unrelated to headaches. Note what you were doing, eating or drinking before the headache began. Also note how long the headache lasted. Include the medicines and amounts you took to treat the headache.
• Write down key personal information, including major stresses or recent life changes.
• List questions to ask your health care provider.

For medication overuse headaches, some questions to ask your health care provider include:

• How could I cause a headache with medicine I took to treat a headache?
• Could there be other reasons for my headaches?
• How can I stop these headaches?
• Are there alternatives to the approach you're suggesting?
• If my original headaches return, how can I treat them?
• Are there brochures or other printed material I can have? What websites do you recommend?

Don't hesitate to ask any other questions.

What to expect from your doctor

Your health care provider will ask questions about your headaches, such as when they started and what they feel like. The more your provider knows about your headaches and medicine use, the better care your provider can give you. Your provider may ask:

• What type of headache do you usually have?
• Have your headaches changed in the past six months?
• How severe are your symptoms?
• What headache medicines do you use, and how often?
• Have you increased the amount or frequency of taking them?
• What side effects have you had from medicines?
• Does anything help improve your symptoms?
• What, if anything, appears to worsen your symptoms?

What you can do in the meantime

Until your appointment, take your medicine only as directed by your health care provider. And take care of yourself. Healthy lifestyle habits can help prevent headaches. They include getting enough sleep, eating plenty of fruits and vegetables, and getting regular exercise. Avoid any known headache triggers.

A headache diary can be very helpful for your health care provider. Keep track of when your headaches occurred, how severe they were and how long they lasted. Also write down what you were doing when the headache began and what your response to the headache was.
