Treating Migraine in Teenagers

Less commonly used for intermittent prophylaxis are the shorter-acting triptans, but they have shown some efficacy as well. In one prospective study using oral sumatriptan 25 mg TID for 5 days each cycle starting 2 to 3 days before onset of menses, there seemed to be at least some improvement with sumatriptan in most cycles treated [90].Zolmitriptan was studied in one prospective double-blind placebo-controlled study using 2.5 mg BID or 2.5 mg TID for 7 days total with each cycle and was found to be associated with a significant reduction in headache frequency as compared with placebo [91].There has been one prospective trial using eletriptan 20 mg TID for 6 days total starting 2 days prior to menses, which also showed improvement in headache activity in 55% of patients [92].

Hormonal Contraceptives

In general for adult patients, hormonal contraceptives are not considered first-line treatment for menstrually related migraine. However, in patients who do not respond to other modes of treatment, or who plan to use hormonal contraception for contraceptive purposes, published expert opinions have recommended considering extended or continuous hormonal regimens [93,94].

Estrogen withdrawal during the luteal phase of the monthly cycle has long been speculated to be of importance in the pathophysiology of menstrually related migraine [93]and the relationship between hormonal contraceptives and migraine is complicated. Headache is a commonly reported side effect of combined hormonal contraceptives [95]; however, this effect seems to occur mostly during the hormone-free week [96]. It has been shown that headache occurs less frequently in women using an extended cycle regimen (84 or 168 days) as compared to those using a traditional monthly cyclic regimen [97,98].Studies addressing the use of combined hormonal contraceptives for women specifically with menstrually related migraine are limited. One small prospective randomized study showed improvement in menstrually related migraine in patients treated with a low dose (20 mcg ethinyl E[2]) oral hormonal contraceptive in both a 21/7 cycle and a 24/4 cycle, with more improvement in the group using a 24/4 cycle [99].Another showed improvement in menstrually related migraine in all study patients treated with a low-dose hormonal contraceptive (20 mcg ethinyl estradiol) on a 21/7 regimen, but with additional 0.9 mg conjugated equine estrogen during the placebo week [100].There has been one randomized placebo-controlled double-blind trial in patients with menstrually related migraine using an extended 168 hormonal regimen along with frovatriptan vs. placebo for 5 days during the hormone-free interval. Overall daily headache scores were decreased from pre-study cycles, and the increase in headaches during the hormone-free interval was lower in the frovatriptan group [101].A recent study showed that contraceptive-induced amenorrhea can be beneficial for decreasing migraine frequency in patients with menstrual migraine [102].There have been no studies addressing the use of hormonal contraceptives for migraine management in adolescents.

In adolescents, the decision regarding use of hormonal contraceptives is more complicated. There is less of a chance that adolescent patients, especially younger ones, would be planning to use hormones for contraception so their use may be solely for the purpose of migraine management. However, hormonal contraceptives are commonly used in adolescents for management of other menstrual-related disorders, such as menorrhagia, dysmenorrhea, and endometriosis, and extended cycle and continuous regimens have become more popular with adolescent providers in general [103].The general concern with using hormonal contraceptives in adolescents is that they have potential for longer-term use than adult patients, and the effects of using hormonal contraceptives long term are unknown. The major concerns are for potential interference with expected increase in bone mineral density in adolescents, effects on fertility, and risk for cancer and cardiovascular disease [103].Additionally, specifically in migraine patients, is the concern for increased stroke risk. The increased risk for ischemic stroke in patients with migraine, although more specifically with migraine with aura, is well known [104–106]and migraine has recently been shown to be a risk factor for ischemic stroke in adolescents as well [107]. In adults, the use of hormonal contraceptives in patients with migraine with aura is known to increase the risk of ischemic stroke [106],and this has not been studied in adolescents. Given the various unknowns in the use of hormonal contraceptives in patients with menstrually related migraines, we would not recommend this as first-line treatment. However, similarly to adults, in patients who do not respond to other methods of migraine management, or who seek to use hormonal contraceptives for contraception or for other menstrually related disorders, extended or continuous cycle hormonal contraceptives may be a reasonable option, at the lowest possible estrogen dose. However, migraine with aura should be screened for, and its presence should prompt reconsideration of combined hormonal contraceptive use.
