If your symptoms do not improve within 2 to 3 weeks, or if they become worse, check with your doctor.

It is very important that your doctor check your progress at regular visits.

Check with your doctor immediately if blurred vision, eye pain, red-green color blindness, or loss of vision occurs during treatment . Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor). Also, make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert or able to see well.
