Headache. 2009 Jan;49(1):136-9. Cluster headache during pregnancy: case report and literature review.

A 32-year-old pregnant woman presented with cluster headache (CH) during the third trimester of a normal pregnancy. Pure oxygen mask inhalation was ineffective, and intranasal lidocaine applications were realized associated with oral methylprednisolone, given at 1 mg per kg once daily. These treatments rendered the pain tolerable and the pregnancy went to its term with no consequence on the baby. This case of CH attack during pregnancy raises the issues of the influence of sexual hormonal changes in women with CH and the way to treat this disease in such circumstance. To date, there are no therapeutic guidelines available; this case suggests some possibilities.

OBJECTIVE: To report and evaluate available data on the use of serotonin 5-HT(1) agonists (triptans) during pregnancy. DATA SOURCES: A PubMed search, limited to English-language articles on human subjects, was conducted (1990-December 2007) using the search terms pregnancy, migraine, and the individual triptan drug names. In addition, the manufacturers of all 7 available triptans were contacted regarding the existence of a pregnancy registry for their drug(s) and the availability of registry reports. STUDY SELECTION AND DATA EXTRACTION: All retrospective and prospective studies reporting on pregnancy outcomes after the use of a triptan were included and critically evaluated. Data from all available manufacturer-sponsored pregnancy registries were also included. DATA SYNTHESIS: Safe and effective treatment of migraine during pregnancy is imperative. DATA INVOLVING SUMATRIPTAN AND, TO A LESSER EXTENT, NARATRIPTAN AND RIZATRIPTAN, EXIST PRIMARILY REGARDING EXPOSURE IN THE FIRST TRIMESTER. THESE DATA SHOW NO SIGNIFICANT DIFFERENCES IN CONGENITAL MALFORMATIONS OR POOR PREGNANCY OUTCOMES WHEN COMPARED WITH EXPECTED RATES IN THE GENERAL POPULATION OR WITH THE OBSERVED RATES IN CONTROL SUBJECTS. THERE IS VERY LITTLE INFORMATION REGARDING EXPOSURE IN MIDDLE AND LATE PREGNANCY. CONCLUSIONS: SUMATRIPTAN APPEARS TO BE A SAFE TREATMENT ALTERNATIVE FOR PREGNANT WOMEN WHO EXPERIENCE NEW-ONSET OR WORSENED MIGRAINES IN THE FIRST TRIMESTER. FURTHER OBSERVATION IS NEEDED PRIOR TO RECOMMENDING ITS USE IN LATER TRIMESTERS. BASED UPON AVAILABLE DATA, THE OTHER AGENTS IN THIS CLASS CANNOT BE RECOMMENDED FOR USE DURING PREGNANCY AT THIS TIME.

The triptans are a class of tryptamine-based drugs indicated for in the treatment of migraine headaches. The triptans act as serotonin (5-hydroxytriptamine) (5-HT) agonists by binding to various serotonin receptors, causing vasoconstriction and neuronal inhibition to alleviate migraines. There are 7 types of triptans currently available on the U.S. market: almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan and zolmitriptan. The objective of this study was to examine the use and effects of triptans in pregnancy. ALTHOUGH THREE OF THE TRIPTANS HAVE PREGNANCY REGISTRIES MAINTAINED BY THE MANUFACTURER, TRIPTAN USE IN PREGNANCY HAS NOT BEEN EXTENSIVELY STUDIED. INFORMATION ON THE USE OF SUMATRIPTAN DURING PREGNANCY IS RELATIVELY MORE ABUNDANT, BECAUSE IT HAS BEEN ON THE MARKET LONGER THAN THE OTHER TRIPTANS AND MAY ALSO HAVE A HIGHER PERCENTAGE OF THE MARKET SHARE. THERE ARE NO DATA TO SUGGEST TERATOGENICITY FOR ANY OF THE TRIPTANS, ALTHOUGH PRETERM BIRTH RATES APPEAR TO BE ELEVATED.

ISSN 0333-1024Cluster headache is a rare disorder in women, but has a serious impact on the affected woman's life, especially on family planning. Women with cluster headache who are pregnant need special support, including the expertise of an experienced headache centre, an experienced gynaecologist and possibly a teratology information centre. The patient should be seen through all stages of the pregnancy. A detailed briefing about the risks and safety of various treatment options is mandatory. In general, both the number of medications and the dosage should be kept as low as possible. PREFERRED TREATMENTS INCLUDE OXYGEN, SUBCUTANEOUS OR INTRANASAL SUMATRIPTAN FOR ACUTE PAIN AND VERAPAMIL AND PREDNISONE/PREDNISOLONE AS PREVENTATIVES. IF THERE IS A COMPELLING REASON TO TREAT THE PATIENT WITH ANOTHER PREVENTATIVE, GABAPENTIN IS THE DRUG OF CHOICE. WHILE BREASTFEEDING, OXYGEN, SUMATRIPTAN AND LIDOCAINE FOR ACUTE PAIN AND PREDNISONE/PREDNISOLONE, VERAPAMIL, AND LITHIUM AS PREVENTATIVES ARE THE DRUGS OF CHOICE. As the individual pharmacokinetics differ substantially, adverse drug effects should be considered if unexplained symptoms occur in the newborn.

Issues about med effects are sufficiently complex and fluid that I would work closely with your ob doc and, ideally, with a headache specialist (acting as a consultant). Given where you are in your pregnancy, you might print out this message and show to your doc. ---- CNS Drugs. 2003;17(1):1-7. Safety of sumatriptan in pregnancy: a review of the data so far. Loder E. Harvard Medical School, Boston, Massachusetts, USA. eloder@partners.org The high prevalence of migraine in women during their reproductive years means that new drug treatments for migraine, such as the serotonin 5-HT(1B/1D) receptor agonists (the 'triptans'), are likely to be widely used by women of childbearing potential. Scrutiny of these agents in an effort to detect any signal of teratogenicity is thus important. A systematic review of the medical literature was conducted to identify information regarding the safety of sumatriptan during pregnancy. This agent was chosen to be investigated because it has been available for the longest and is the most widely used of the triptan class. Information was obtained regarding the impact of migraine on pregnancy outcome, and data on sumatriptan use in pregnancy were obtained from animal studies, preclinical drug trials, postmarketing surveillance efforts, prospective pregnancy registries, national birth registries and teratogen information services. Synthesis of information from these sources is sufficient to rule out a large increase in birth defects from sumatriptan use during pregnancy and is reassuring for cases where inadvertent exposure to sumatriptan during pregnancy has occurred. However, current information is not sufficient to rule out small increases in the risk for birth defects. For this reason, caution should be exercised in making a positive recommendation for the use of sumatriptan during pregnancy.

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. === OTC meds are not very helpful with cluster, as you know, but may be one of the few options available to you. Some folks have good luck aborting/easing an attack by applying an ice pack to the pain site. Others find very hot water also works; others have used a hair dryer blasting the pain site works! No predicting; just try.
