Aspirin for the prevention of migraine in pregnancy: a retrospective, descriptive case series from a tertiary centre
Abstract
STUDY OBJECTIVE
To assess the use of low-dose aspirin for the prevention of migraine in pregnant women.
DESIGN
This was a single-centre, retrospective, descriptive case series. Data were obtained through a retrospective review of electronic clinical records. Data are reported on migraine history and pharmacological management of migraine prior to and during the index pregnancy, as well as maternal and neonatal outcomes.
SETTING
A specialist obstetric medicine clinic in London, UK.
PARTICIPANTS
Pregnant women seen due to headache in the clinic between January 2020 and August 2023, with a diagnosis of 'migraine' in their electronic clinical records were selected for this study. 73 patients were eligible for inclusion.
INTERVENTIONS
Patients received routine clinical care as determined by the clinical team at the time; no study-specific interventions were applied.
MAIN OUTCOME MEASURE(S)
The main outcomes were frequency of low-dose aspirin use for migraine prevention in pregnancy, and change in migraine symptoms after aspirin was started for migraine prevention.
RESULTS
Pharmacological prevention for migraine was used by 66/73 (90%) women. Low-dose aspirin was taken for migraine prevention by 61/73 (86%); 36/61 (59%) had aspirin monotherapy and the remainder took more than one medication for this indication. In the aspirin monotherapy group, 30/31 (97%, 5/36 not documented) subsequently reported an improvement in their migraine. Maternal and neonatal outcomes were consistent…
