A new treatment for motion sickness in patients with migraines was reported by a group of doctors from Pittsburgh.  Giving migraine sufferers who are prone to motion sickness a migraine drug, rizatriptan (Maxalt) prevented motion sickness . There were 25 subjects in the study and 15 of them developed motion sickness after being rotated in the darkness. Of these 15 patients, 13 showed decreased motion sickness after being pretreated with rizatriptan. This was a small study and not all patients benefited, but this is an option that should be considered in patients who suffer from severe motion sickness.  It is likely that the effect is not specific to rizatriptan, but that sumatriptan (Imitrex), eletriptan (Relpax) and other triptans are also effective.  However, just like when treating migraine attacks, it is possible that some patients will respond better to one triptan and others to another.

During pregnancy, two thirds of women stop having migraine headaches.  However, one third continues to have them, and sometimes even worsen during pregnancy.   As a general rule, only acetaminophen (Tylenol) is considered safe, but for most migraine sufferers it is completely ineffective.  Codeine is also benign, but it also either does not work or causes side effects, such as nausea and sedation.  Triptans, such as sumatriptan (Imitrex), rizatriptan (Maxalt), and other are very effective for migraines, but are not proven to be as safe.  Pregnancy registries in the US have information on over 1,500 women who took a triptan during pregnancy and so far the drugs look safe for the baby.  A new study from Norway in the February issue of Headache reports on another 1,535 women who took triptans during pregnancy and compared them to 68,000 women who did not.  This study also found no increased risk of congenital malformation, even if triptans were taken in the first trimester.  Women who took triptans in the second and third trimester also had healthy babies, but they had a slightly increased risk of atonic uterus and bleeding during labor.

Treatment of menstrual migraines often is more difficult than of non-menstrual attacks.  A double-blind study by Marcelo Bigal and his collaborators just published in Headache shows that a combination of 10 mg of rizatriptan (Maxalt) and 4 mg of a steroid medication, dexamethasone (Decadron) is more effective than either drug alone.  Both drugs are effective in treating many refractory migraine attacks (although I usually use 8 mg of dexamethasone), this is the first trial of two drugs together.  While the results are not very surprising, the study may lead to wider acceptance of combination therapy and better relief for many women.  While in the past the emphasis was placed on finding a single drug to treat a disease, in recent years combination therapy has become a standard approach in many conditions.  Treximet, a combination of sumatriptan (Imitrex) and naproxen (Aleve) was also shown to be better than either of the two ingredients alone.

Menstrual migraines are at times very difficult to treat.  Triptans, such as Maxalt, Imitrex and other are usually very effective, but in some patients do not provide sufficient relief.  Corticosteroid drugs, such as prednisone and dexamethasone can help some patients.  Marcelo Bigal and his colleagues compared treatment of menstrual migraines with Maxalt alone, dexamethasone alone, and combination of the two.  Maxalt was much better than dexamethasone, providing sustained 24-hour relief in 63% of patients vs 33%, but the combination was better than Maxalt alone, giving relief to 82% of women.  We would always try Maxalt or a similar drug alone, but if one drug is insufficient a combination with dexamethasone should be tried.  Corticosteroids should not be used for more than a few days a month because frequent and prolonged use can lead to serious side effects.
