Precautions
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. Also, check with your doctor immediately if blurred vision or any loss of vision, with or without eye pain, occurs during treatment. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
Since this medicine may cause blurred vision or loss of vision, 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 able to see well.
If this medicine causes clumsiness; unsteadiness; or numbness, tingling, burning, or pain in the hands and feet, check with your doctor immediately. These may be early warning symptoms of more serious nerve problems that could develop later.
