Which of the following is a common side effect of timolol eye drops?

• A. Nausea
• B. Stinging discomfort, occasional conjunctivitis, blurred vision, photophobia, dry eyes
• C. Hair loss
• D. Tinnitus

Answer: (B)

Topical timolol lowers eye pressure by reducing aqueous humor production, but placing the drop in the eye often causes local irritation. The most common effects are stinging or burning on instillation, occasional conjunctival irritation, blurred vision, sensitivity to light (photophobia), and dry eyes. These reflect the eye’s immediate reaction to the medication on contact and are the usual, expected side effects of this ophthalmic preparation. Nausea, hair loss, or tinnitus aren’t typical for timolol eye drops and would not be expected from this route of administration unless there’s significant systemic absorption or another issue. If systemic symptoms such as slow heart rate, low blood pressure, or bronchospasm occur, seek medical attention, but they’re not the common local adverse effects. If stinging or blurred vision remains bothersome, discuss with a clinician for management.
