Vestibular Migraine in a Female With Unexpected Pregnancy

In the first three months of pregnancy, 23.8% of females experience migraines, and 63.6% have episodes of dizziness, with the most frequent symptom being (35.7%) vertigo. Therefore, vestibular migraine is expected to occur in pregnant women, yet studies in this regard are limited in the literature. We studied such a case in order to determine the safest treatment for patients with possible pregnancy. The studied case was a 37-year-old female, who had a history of migraines. She had had vestibular migraines eight times since she was 29 years old. During the second attack, she had been conservatively treated with several anti-vertigo and anti-emetic medications. Because her menses was a little out of schedule, she receive pregnancy test, and to our surprise, the test showed positive results. Afterwards, she was transferred to an obstetric hospital for prenatal examinations and had follow-ups for ten months. Eight months after delivery, the third vestibular migraine occurred. Because of lactation, she did not take any medications; vertigo continued for half a day, and dizziness remitted over the following two days. Pregnancy is expected to occur together with vertigo in females of the childbearing age, even if they have been diagnosed with sterility. Any anti-vertiginous medication with teratogenic risk should be avoided if pregnancy is not completely excluded, antihistamine diphenhydramine (FDA class B) are recommended first for symptomatic control.
