How to Use ketotifen
This medicine is only for use in the eye. Do not take by mouth. Follow the directions on the prescription label. Wash hands before and after use. Tilt the head back slightly and pull down the lower eyelid with the index finger to form a pouch. Try not to touch the tip of the dropper to your eye, fingertips, or any other surface. Squeeze the prescribed number of drops into the pouch. Close the eye gently to spread the drops. Your vision may blur for a few minutes. Use your doses at regular intervals. Do not use your medicine more often than directed. If you use other eye medicines, they should be used at least 10 minutes before or after this medicine. Eye ointments should be applied last.
Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed. While this drug may be prescribed for children as young as 3 years of age for selected conditions, precautions do apply.
They need to know if you have any of these conditions:
- wear contact lenses
- an unusual or allergic reaction to ketotifen, other medicines, foods, dyes, or preservatives

If you miss a dose, use it as soon as you can. If it is almost time for your next dose, use only that dose. Do not use double or extra doses.
Tell your doctor or health care professional if your symptoms do not start to improve in 2 or 3 days.
Report any serious side effects promptly. Stop using this medicine if your eyes get swollen, painful, or have a discharge, and see your doctor or health care professional as soon as you can.
