When to stop using eye drops and see a doctor

Quell’s label is specific about this. In full: Stop use and ask a doctor if you feel eye pain or changes in your vision, if irritation or redness continues, or if the condition worsens or persists for 72 hours.

Stop means stop

The instruction is to stop use and ask a doctor, not to try a different drop first or to use more of this one. If you have reached one of those points, the next step is an appointment.

Pain and vision come first

Eye pain and changes in your vision are listed first in that sentence, and neither has a waiting period attached. Don’t wait out the 72 hours for those.

When it can’t wait at all

Sudden vision loss, eye pain or an eye injury call for emergency care straight away. For a medical emergency, call your local emergency number.

Take the label with you

Bring the carton, or open the Drug Facts page, at the appointment, so the doctor can see exactly what you have been using and how often.
