Correct answer: E — Counsel on correct inhaler use and to seek help for acute eye pain or visual halos
Inhaled antimuscarinics can precipitate or worsen narrow-angle glaucoma if the medicine enters the eyes. The patient should be counselled on technique, avoiding eye exposure, and seeking urgent advice for acute eye pain, red eye, or halos. The prescription may still be appropriate but warrants careful counselling and prescriber awareness.
