Introduction: Response to indomethacin is an essential feature for the diagnosis of both paroxysmal hemicrania (PH) and hemicrania continua (HC). Cluster headache (CH) is widely considered to be a disease unresponsive to indomethacin. Case reports: We report four patients with CH who responded to indomethacin. Two patients, who were refractory to the usual therapy for CH, fulfilled the criteria for chronic CH. Conversely, two patients had a history of episodic CH and showed response to both…

Can response to indomethacin exclude the diagnosis of cluster headache?
This paper inspires us to re-think the diagnostic criteria of trigeminal autonomic cephalalgias (TACs) in the International Classification of Headache Disorders, 2nd edn (ICHD-2) (2).
A case of remitting hemicrania continua with seasonal variation and clustering: a diagnostic confusion with cluster headache
It is suggested that remitting subtype of HC may mimic custer headache, and a therapeutic trial of indomethacin should be done in all strictly unilateral headaches who are not responding to other drugs.
A retrospective observation on 105 patients with chronic cluster headache receiving indomethacin
Clinical features of IMC responders in a retrospective cohort of chronic cluster headache patients are described and an IMC test as a third-line treatment in CCH is recommended.
Indomethacin-Responsive Headaches

These “novel” indomethacin-responsive headaches beg the question of what headache characteristics are required to qualify a headache as an indomethin-responsive headache, and challenge the concept of using a therapeutic intervention as a diagnostic criterion.
Paroxysmal hemicrania: a retrospective study of a consecutive series of 22 patients and a critical analysis of the diagnostic criteria
A subset of patients may not have all the defined features of PH and there is a need for refinement of the existing diagnostic criteria.
Primary continuous unilateral headaches: A nosologic model for hemicrania continua
There seems to be a syndrome of ‘primary continuous unilateral headache’ with at least two distinctive categories: hemicrania continua and hemicania incerta, which are differentiated by their respective response to indomethacin.
Coexistence of contralateral cluster headache and probable paroxysmal hemicrania: a case report
There is a clear overlap in clinical diagnosis between cluster headache (CH) and paroxysmal hemicrania (PH) and similarities are somewhat greater than differences and it could be suggested that a continuous hypothalamic activation give a maladaptive plasticity recruiting closed neuronal aggregates responsible for the developing of PH after a long period of CH.
Indomethacin‐Responsive TACs (Paroxysmal Hemicrania, Hemicrania Continua, and LASH): Further Proof of a Distinct Spectrum of Headache Disorders
  • T. Rozen
  • Medicine, Psychology
  • 2013
A case of indomethacin-responsive HC that had distinct features of LASH is presented, helping to establish the indomethin-responsive TAC spectrum.
Trigeminal Autonomic Cephalalgias
Although much less common than other headache disorders seen in clinical practice, recognition of the TACs is especially important as they are among the most severe and disabling syndromes in headache medicine.
O004. Refractory chronic cluster headache responding absolutely to indomethacin
The case of a male with refractory chronic CH, who responded both acutely and prophylactically to indomethacin, is reported.


A Patient with Cluster Headache Responsive To Indomethacin: Any Relationship with Chronic Paroxysmal Hemicrania?
This case report describes a CH patient responsive to indomethacin, suggesting that the drug might provide a further chance to treat the active CH period, given that controlled clinical trials are provided and that CH and PH share some pathophysiological mechanisms.
A Patient With Chronic Cluster Headache Responsive to High-Dose Indomethacin: Is There an Overlap With Chronic Paroxysmal Hemicrania?
A case of C CH responding to high-dose indomethacin when other treatments failed and the relationship of CCH to CPH is reported, which is incumbent on the clinician to exhaust all potential medical options.
Parenteral Indomethacin (The Indotest) in Cluster Headache
The use of a test dose of 100 mg i.m. indomethacin (INDOTEST) appears to provide a clear-cut answer in this situation and may be a useful tool for a proper clinical assessment of unilateral headache with relatively short-lasting attacks when problems of classification arise.
Cluster Headache and Paroxysmal Hemicrania: Differential Diagnosis
Clinical features that distinguished cluster headache and paroxysmal hemicrania patients were: maximal pain localization, ocular in CH patients and extra-ocular in PH group; mean attack duration was longer and mean attack frequency was lower inCH patients in comparison with PH patients.
Paroxysmal hemicrania and cluster headache: two discrete entities or is there an overlap?
There is increasing evidence that paroxysmal hemicrania and cluster headache share a similar pathogenesis and that they may not always be so discrete in either their response to indomethacin or their periodicity.

This study confirms the existence of auras and interictal signs and symptoms in patients with chronic CH, and male sex and smoking as CH risk factors, and primary and secondary chronic CH appear equally prevalent.
