What are the best treatments for Hemicrania Continua?

Hemicrania Continua is a rare form of primary headache characterized by a continuous, unilateral pain with periods of exacerbation that is uniquely and absolutely responsive to the medication indomethacin. Treatment focuses on stabilizing this daily pain through strictly monitored pharmacological intervention, often requiring a multidisciplinary approach to manage long-term side effects and symptom control.

What is the gold-standard treatment for Hemicrania Continua?

The hallmark of Hemicrania Continua diagnosis and treatment is an absolute, rapid response to indomethacin (Indocin). Because Hemicrania Continua is defined by this sensitivity, clinicians often use a "therapeutic trial" of indomethacin to confirm the diagnosis. While highly effective, the medication carries significant gastrointestinal and cardiovascular risks, necessitating the lowest effective dose and often the addition of gastroprotective agents.

What other medications are used if indomethacin is not tolerated?

When patients cannot tolerate the side effects of indomethacin, or if Hemicrania Continua requires alternative management, physicians may explore other options, though these are generally less effective than the primary treatment:

• Topiramate (Topamax)


• Gabapentin (Neurontin)


• Melatonin, which has shown efficacy in some clinical case series


• Occipital nerve blocks or trigger point injections


• Botulinum toxin (Botox) injections for chronic migraine-like features

Which specialists should be on a Hemicrania Continua care team?

Managing Hemicrania Continua effectively requires a coordinated, multidisciplinary team. We recommend patients consult with a headache specialist or neurologist who is familiar with rare trigeminal autonomic cephalalgias. Depending on the patient's specific presentation, the care team may include:

1. A neurologist specializing in headache disorders.


2. A gastroenterologist to monitor for potential side effects of long-term NSAID use.


3. A pain management specialist for interventional procedures.


4. A clinical psychologist to support the emotional impact of living with a chronic, daily headache condition.

Is there hope for new treatments for Hemicrania Continua?

Research into Hemicrania Continua is evolving, with current clinical interest focused on neuromodulation devices, such as non-invasive vagus nerve stimulation (nVNS), which may offer relief for patients who struggle with medication side effects. While large-scale clinical trials remain limited due to the rarity of the condition, our community of 86 members at DiseaseMaps.org continues to share valuable insights into how different treatment protocols affect daily quality of life.

Next steps

• Maintain a detailed headache diary to track pain intensity and response to medication.


• Consult a board-certified neurologist to discuss an indomethacin trial.
