It's an old treatment for migaine but I've never seen it mention for Cluster.
Your fear of Imitrex is misplaced. All of the safety evaluations have set aside any major concerns.
Search of PubMed in 3/09 found no abstract later than 2004 and none specific to Cluster Headache. =============================================================

BACKGROUND: Triptans are widely used to treat migraine but have been associated with stroke, myocardial infarction (MI), and ischemic heart disease (IHD) in case reports. OBJECTIVE: To estimate the incidence of stroke, cardiovascular events, and death in a migraine cohort, stratified by triptan prescription, and investigate whether the risk of these events was increased in those treated with triptans. METHODS: Migraine patients and matched nonmigraine control subjects were identified from the General Practice Research Database. Computerized records were searched for triptan prescriptions, stroke, TIA, MI, IHD, death, arrhythmia, and confounding variables. Incidence rates were calculated and migraine groups compared with controls using a Cox model, adjusting for confounders. RESULTS: Of 63,575 migraine patients, 13,664 were prescribed a triptan. There was no association between triptan prescription and stroke (hazard ratio [HR] 1.13; 95% CI 0.78, 1.65), MI (HR 0.93; 95% CI 0.60, 1.43), or other outcomes studied. The larger group of migraine patients not prescribed a triptan had an increased risk of stroke (HR 1.51; 95% CI 1.26, 1.82) and IHD (HR 1.35; 95% CI 1.18, 1.54) and a decreased risk of all-cause mortality (HR 0.72; 95% CI 0.65, 0.80). CONCLUSIONS: IN GENERAL PRACTICE, TRIPTAN TREATMENT IN MIGRAINE DOES NOT INCREASE THE RISK OF STROKE, MI, CARDIOVASCULAR DEATH, IHD, OR MORTALITY. TRIPTANS ARE PRESCRIBED TO THOSE LESS AT RISK OF THESE EVENTS.

Olanzapine as an Abortive Agent for Cluster Headache.
Rozen TD.
Department of Neurology, Jefferson Headache Center/Thomas Jefferson University Hospital, Philadelphia, Pa.
OBJECTIVE: To evaluate olanzapine as a cluster headache abortive agent in an open-label trial. BACKGROUND: Cluster headache is the most painful headache syndrome known. There are very few recognized abortive therapies for cluster headache and fewer for patients who have contraindications to vasoconstrictive drugs. METHODS: Olanzapine was given as an abortive agent to five patients with cluster headache in an open-label trial. THE INITIAL OLANZAPINE DOSE WAS 5 MG, AND THE DOSE WAS INCREASED TO 10 MG IF THERE WAS NO PAIN RELIEF. THE DOSAGE WAS DECREASED TO 2.5 MG IF THE 5-MG DOSE WAS EFFECTIVE BUT CAUSED ADVERSE EFFECTS. To be included in the study, each patient had to treat at least two attacks with either an effective dose or the highest tolerated dose. RESULTS: Five patients completed the investigation (four men, one woman; four with chronic cluster, one with episodic cluster). Olanzapine reduced cluster pain by at least 80% in four of five patients, and TWO PATIENTS BECAME HEADACHE-FREE AFTER TAKING THE DRUG. Olanzapine typically alleviated pain within 20 minutes after oral dosing and treatment response was consistent across multiple treated attacks. The only adverse event was sleepiness. CONCLUSIONS: Olanzapine appears to be a good abortive agent for cluster headache. IT ALLEVIATES PAIN QUICKLY AND HAS A CONSISTENT RESPONSE ACROSS MULTIPLE TREATED ATTACKS. IT APPEARS TO WORK IN BOTH EPISODIC AND CHRONIC CLUSTER HEADACHE.

Olanzapine has a brand name of "Zyprexa" and is a antipsychotic. Don't be put off by this primary usage. Several of the drugs used to treat CH are cross over applications, that is, drugs approved by the FDA for one purpose which are found to be effective with unrelated conditions--BJ. ===== Since this abstract was first posted Zyprexa has appeared in some lists of recommended meds for CH.
