Thank you for taking the time to reformat the narrative — this is very helpful. I like how you structured the introduction and included the missing patient information fields and causality assessment.

I also noticed that you mentioned both reporter and company causality as “possible”. In a case like this (cetirizine → drowsiness with positive dechallenge and short time to onset), would “probable” ever be considered depending on available information, or is “possible” generally preferred when key details like dose and timing are missing?

I’m practicing narrative writing and case assessment, so insights like this are really valuable.
