A 29-year-old woman comes to the clinic complaining of headaches, nausea and vomiting, and blurred vision that have been going on for two days.

She has been wearing glasses since she was a child due to her long-sightedness. She has a history of severe migraines and was recently prescribed a prophylactic medication by her GP.

During the examination, both of her eyes appear red, and her pupils are mid-dilated and unreactive in both eyes.

What is the probable medication responsible for this presentation?
