If a patient on Microgynon ED experiences sudden disturbance of vision, what should be done?

• A. Stop it immediately
• B. Continue as planned
• C. Take a dose of vitamin C
• D. Consult an optometrist within 24 hours

Answer: (A)

Sudden vision changes on a combined hormonal contraceptive signal a possible vascular event, such as retinal ischemia or a thromboembolic stroke. The estrogen in Microgynon ED increases the blood’s tendency to clot, so stopping the medication right away reduces ongoing exposure and the risk of further clotting while you seek urgent evaluation.

Go to emergency care or an urgent medical service promptly to determine the cause and receive appropriate treatment. This isn’t something that should wait for routine eye care or a later visit. Vitamin C won’t address vascular or clotting issues, and delaying care for up to 24 hours with an optometrist visit could allow a serious problem to worsen. The priority is urgent medical assessment after stopping the pill.
