Insights
Hemicrania continua (HC) is a rare headache disorder. This case report highlights pregabalin as a potential treatment for patients with indomethacin-resistant HC.
Area of Science:
- Neurology
- Headache Medicine
Background:
- Hemicrania continua (HC) is a rare primary headache disorder characterized by continuous unilateral headaches with superimposed exacerbations.
- Diagnostic criteria for HC mandate a complete response to indomethacin treatment.
Observation:
- This case report details a patient with HC who exhibited resistance to indomethacin therapy.
- The patient experienced significant relief from headache symptoms upon initiation of pregabalin treatment.
Findings:
- Indomethacin resistance does not exclude the diagnosis of Hemicrania continua.
- Pregabalin demonstrated efficacy in managing HC symptoms in an indomethacin-resistant patient.
Implications:
- Pregabalin represents a potential therapeutic option for managing Hemicrania continua in cases of indomethacin resistance.
- This finding may broaden treatment strategies for patients with refractory HC.
- Further research is warranted to confirm the efficacy and safety of pregabalin for HC.
Abstract:
Hemicrania continua (HC) is a rare primary headache disorder. It presents some autonomic features (including conjunctival injection, ptosis, eyelid edema, lacrimation, nasal congestion, and rhinorrhea). Response to indomethacin treatment is the mandatory criteria for the diagnosis of HC. However, previously reported literature indicates that there are some reported cases that did not respond to indomethacin. In this case report, we present a patient who had indomethacin resistance with an associated pregabalin response. Pregabalin may be an effective treatment for hemicrania continua in some patients with indomethacin resistance.
