A 38-year-old woman attends a GP appointment, complaining of a headache. She describes a two-week history of daily headaches, which tend to occur in the afternoon and evening, and manifest as an excruciating pain which affects the left side of her face. The pain both begins and resolves suddenly, lasting around 30 minutes each episode, and she is having around half a dozen episodes a day. Her other past medical history includes depression, for which she takes citalopram, and a hiatus hernia, for which she takes lansoprazole. The GP decides to prescribe her a course of sumatriptan.
