Application

Take this medication by mouth; generally twice daily. Do not crush or chew the tablets. Ketotifen must be taken regularly to be effective. Do not skip any doses. Do not stop using other asthma medications unless your doctor tells you to. To lessen the drowsiness effect of this drug, the dosage may be slowly increased during the first week. It may take several weeks before the full benefits of this drug are clearly noticed (usually within 10 weeks). After 2 to 3 months of using this drug, your doctor may slowly decrease the use of other asthma medicines. Follow your doctor's directions carefully.
Do not use this medication if you are allergic to ketotifen, or if you have an untreated eye infection. Ketotifen ophthalmic should not be used to treat eye irritation caused by wearing contact lenses.
Use this medication exactly as directed on the label, or as it has been prescribed by your doctor. Do not use the medication in larger amounts, or use it for longer than recommended.
If you wear contact lenses, remove them before applying ketotifen ophthalmic. This medication may contain a preservative (benzalkonium chloride) that may cause discoloration of contact lenses. Wait at least 10 minutes after using in the eye drops before putting contact lenses into your eyes.
Do not allow the medicine dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.
