Cluster headache is a rare, clinically well-characterized disabling disorder that occurs in both episodic and chronic forms. The very painful short-lived unilateral headache attacks are associated with autonomic dysfunction. A large number of drugs such as ergotamines, steroids, methysergide, lithium carbonate, verapamil, valproate, capsaicin, leuprolide, clonidine, methylergovine maleate, methylphenidate, and melatonin are considered beneficial for prophylaxis. Nevertheless, this extremely painful condition is occasionally refractory to conventional treatment. The antispastic agent baclofen has been shown to possess an antinociceptive activity. Its efficacy in neuralgias, central pain following spinal lesions, painful strokes, migraine, and medication misuse chronic daily headache suggests that it may be useful for prevention of cluster headache attacks. Therefore, we treated 16 symptomatic patients with cluster headache with daily baclofen, 15 to 30 mg, in three divided doses for the cluster period and 2 weeks after. Within a week, 12 patients reported the cessation of attacks. One was substantially better and became attack free by the end of the following week. In the remaining three patients, the attacks worsened and corticosteroids were prescribed. One of these was also given verapamil. Three of the 16 patients had an additional cluster period, which cleared with a second course of baclofen. In this pilot study, baclofen seemed to be effective, safe, and well tolerated for cluster headache, and seemed to retain its efficacy on repeated clusters.

BACKGROUND: A beneficial prophylactic effect from eletriptan 40 mg given to a single patient with cluster headache was observed. OBJECTIVE: To further evaluate the efficacy of eletriptan in the short-term prophylaxis of cluster headache. METHODS: We treated 18 patients; mean age, 40.5 years (standard deviation [SD], 9.9). The number of cluster headache attacks was recorded during a baseline period of 6 days, and during 6 days of treatment with eletriptan 40 mg twice daily. The primary outcome measure was the reduction in the number of attacks during the treatment period. RESULTS: In the 16 patients who completed the study (2 patients were lost to follow-up), the mean total number of attacks decreased from 10.9 (SD, 5.6) during baseline to 6.3 (SD, 3.7) during treatment with eletriptan (P=.01) The reduction in the number of attacks exceeded 50% in 6 patients. CONCLUSION: This small open-label study suggests that eletriptan 40 mg twice daily may be useful for the short-term prophylaxis of cluster headache.

The authors report rapid cluster headache relief in a 43-year-old man with a 5-year history of refractory cluster headache. The patient described complete headache relief within 10 minutes of taking 10 mg of methylphenidate (Ritalin) when used to abort the onset of his headaches. Subsequently, a scheduled Ritalin dose taken each morning was sufficient to prevent his nightly headaches. In addition, 1 week of prophylactic methylphenidate therapy halted the series of cluster headaches. This is the first reported case of relief of cluster headaches with methylphenidate.

Chronic cluster headache remains refractory to medical therapy in at least 30% of those who suffer from this condition. The lack of alternative medical therapies that are as effective as, or more effective than, lithium carbonate makes new therapies necessary for this highly disabling condition. Based on a previous report, we gave oral anticoagulants to three patients with chronic cluster headache. Two of them remained cluster headache-free while taking warfarin. In the third patient, the use of warfarin for three weeks initially increased the frequency and intensity of cluster headache attacks but subsequently induced a prolonged remission. In spite of the paucity of data available, oral anticoagulation appears to be a promising therapy for chronic cluster headache.
