Improvement of migraine with change from combined hormonal contraceptives to progestin-only contraception with desogestrel: How strong is the effect of taking women off combined contraceptives?

Considerations for Contraceptive Use Among Patients with Migraines

Purpose of Review

There is an overlap in the populations of patients who suffer from migraine headaches and patients who seek contraception. The purpose of this review is to present recent studies on contraception among patients with migraines and provide clinical recommendations.

Recent Findings

Migraine with aura and combined hormonal contraceptive (CHC) use are associated with increased ischemic stroke risk. The use of CHCs in patients with migraine with aura produces a higher risk of ischemic stroke than either factor individually; therefore, CHC is contraindicated in this population by certain guidelines. However, recent studies suggest that oral contraceptive may reduce migraine days, pain scores, and migraine medication use.

Summary

Certain guidelines recommend against use of CHCs in patients with migraine with aura. CHC use is acceptable among patient with migraines without aura. In patients with menstrual-related migraines, there may be benefit from continuous use of oral contraceptives. Further studies are needed on migraine and specific formulations of CHC, if the frequency of migraines with aura impacts ischemic stroke risk and the impact of oral and non-oral contraceptives on menstrual headaches.

Clinical features of migraine with onset prior to or during start of combined hormonal contraception: a prospective cohort study

Many studies have described the features of menstrually related migraines but there is a lack of knowledge regarding the features of migraine in combined hormonal contraceptive users (CHC). Hormone-withdrawal migraines in the pill-free period could differ from those in the natural cycle. Gynaecologic comorbidities, like dysmenorrhea and endometriosis, but also depression or a family history might modify the course of migraine. A better understanding of migraine features linked to special hormonal situations could improve treatment. For this prospective cohort study, we conducted telephone interviews with women using a CHC and reporting withdrawal migraine to collect information on migraine frequency, intensity, triggers, symptoms, pain medication, gynaecologic history and comorbidities (n = 48). A subset of women agreed to also document their migraines in prospective diaries. The mean number of migraine days per cycle was 4.2 (± 2.7). Around 50% of these migraines occurred during the hormone-free interval. Migraine frequency was significantly higher in women who suffered from migraine before CHC start (5.0 ± 3.1) (n = 22) in comparison to those with migraine onset after CHC start (3.5 ± 2.1) (n = 26). Menstrually related attacks were described as more painful (57.5%), especially in women with migraine onset before CHC use (72%) (p < 0.02). Comorbidities were rare, except dysmenorrhea. The majority of migraine attacks in CHC users occur during the hormone-free interval. Similar as in the natural cycle, hormone-withdrawal migraines in CHC users are very intense and the response to acute medication is less good, especially in those women, who developed migraine before CHC use.

Oral contraceptive use and its association with symptomatology in migraine patients

Background:

Hormonal changes in natural menstrual cycles are known to modulate and even worsen headache symptoms in migraineurs; however, the impact of oral contraceptive pills (OCP), including combined oral contraceptive (COC) and progestogen-only pills on migraine symptomatology, is little investigated.

Method:

In this retrospective cohort study of 1758 migraine patients, data from 1032 female patients aged 15–45 years were accessed and their contraceptive methods, if any, were analyzed. Further comparisons were conducted between patients with OCP use and those without OCP use regarding the demographics, headache symptoms, and associated symptoms. Most OCP users in this study were assumed to have used COC, but information of individual hormone content of OCP was not collected. Patients with nonoral hormonal contraceptives were excluded for further comparison.

Results:

The use of OCP was common (47.8%) among the study cohort. Compared to those without OCP use ( n = 410), patients with OCP use ( n = 493) were younger (27.4 ± 7.0 vs. 32.8 ± 7.9, p < 0.001), had lower headache frequency (days per month, 11.1 ± 7.5 vs. 12.3 ± 8.8, p = 0.03), were less likely to have osmophobia (47.3 vs. 54.4%, p = 0.033) or cranial autonomic symptoms (44.8 vs. 53.2%, p = 0.013), and more commonly reported menstrually-related worsening of headache (52.3 vs. 42.4%, p = 0.012). The proportion of migraine with aura or other headache characteristics including severity, unilaterality, and pulsatile characteristic showed no differences between groups.

Conclusion:

Our data provide real-life information about contraceptive use among patients with migraine. The use of OCP is associated with differences in migraine symptomatology. Further studies are needed to determine whether this relationship is causal and any possible underlying mechanism.

Male and female sex hormones in primary headaches

BACKGROUND

The three primary headaches, tension-type headache, migraine and cluster headache, occur in both genders, but all seem to have a sex-specific prevalence. These gender differences suggest that both male and female sex hormones could have an influence on the course of primary headaches. This review aims to summarise the most relevant and recent literature on this topic.

METHODS

Two independent reviewers searched PUBMED in a systematic manner. Search strings were composed using the terms LH, FSH, progesteron*, estrogen*, DHEA*, prolactin, testosterone, androgen*, headach*, migrain*, "tension type" or cluster. A timeframe was set limiting the search to articles published in the last 20 years, after January 1st 1997.

RESULTS

Migraine tends to follow a classic temporal pattern throughout a woman's life corresponding to the fluctuation of estrogen in the different reproductive stages. The estrogen withdrawal hypothesis forms the basis for most of the assumptions made on this behalf. The role of other hormones as well as the importance of sex hormones in other primary headaches is far less studied.

CONCLUSION

The available literature mainly covers the role of sex hormones in migraine in women. Detailed studies especially in the elderly of both sexes and in cluster headache and tension-type headache are warranted to fully elucidate the role of these hormones in all primary headaches.

Effect of exogenous estrogens and progestogens on the course of migraine during reproductive age: a consensus statement by the European Headache Federation (EHF) and the European Society of Contraception and Reproductive Health (ESCRH)

We systematically reviewed data about the effect of exogenous estrogens and progestogens on the course of migraine during reproductive age. Thereafter a consensus procedure among international experts was undertaken to develop statements to support clinical decision making, in terms of possible effects on migraine course of exogenous estrogens and progestogens and on possible treatment of headache associated with the use or with the withdrawal of hormones. Overall, quality of current evidence is low. Recommendations are provided for all the compounds with available evidence including the conventional 21/7 combined hormonal contraception, the desogestrel only oral pill, combined oral contraceptives with shortened pill-free interval, combined oral contraceptives with estradiol supplementation during the pill-free interval, extended regimen of combined hormonal contraceptive with pill or patch, combined hormonal contraceptive vaginal ring, transdermal estradiol supplementation with gel, transdermal estradiol supplementation with patch, subcutaneous estrogen implant with cyclical oral progestogen. As the quality of available data is poor, further research is needed on this topic to improve the knowledge about the use of estrogens and progestogens in women with migraine. There is a need for better management of headaches related to the use of hormones or their withdrawal.

Menstrual migraine: a review of current and developing pharmacotherapies for women

INTRODUCTION

Migraine is one of the most common neurological disorders in the general population. It affects 18% of women and 6% of men. In more than 50% of women migraineurs the occurrence of migraine attacks correlates strongly with the perimenstrual period. Menstrual migraine is highly debilitating, less responsive to therapy, and attacks are longer than those not correlated with menses. Menstrual migraine requires accurate evaluation and targeted therapy, that we aim to recommend in this review.

AREAS COVERED

This review of the literature provides an overview of currently available pharmacological therapies (especially with triptans, anti-inflammatory drugs, hormonal strategies) and drugs in development (in particular those acting on calcitonin gene-related peptide) for the treatment of acute migraine attacks and the prophylaxis of menstrual migraine. The studies reviewed here were retrieved from the Medline database as of June 2017.

EXPERT OPINION

The treatment of menstrual migraine is highly complex. Accurate evaluation of its characteristics is prerequisite to selecting appropriate therapy. An integrated approach involving neurologists and gynecologists is essential for patient management and for continuous updating on new therapies under development.
