How does this medication work? What will it do for me?
Ketotifen belongs to the classes of medications called antiallergics and asthma prophylactics. This medication is used in combination with other medications to treat mild allergic asthma in children.
Ketotifen is an anti-allergy medication that helps to reduce asthma symptoms by reducing the body's response to allergens (substances that cause allergic reactions). These allergens can often trigger an acute asthma attack.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop giving this medication to your child without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as your child. It can be harmful for people to use this medication if their doctor has not prescribed it.
How should I use this medication?
For children 6 months to 3 years of age, the usual recommended dose is based on body weight, 0.05 mg per kilogram of weight twice daily, in the morning and evening.
For children over 3 years of age, the usual recommended dose is 1 mg twice daily, in the morning and evening.
To reduce side effects, your child's doctor may suggest you start with a lower dose and increase to the recommended dose after 5 days.
Many things can affect the dose of medication that a child needs, such as body weight, other medications, or medications. If you doctor has recommended a dose different from the one listed here, do not change the way that you are giving the medication to your child without consulting your doctor.
Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.

Ketotifen does not relieve symptoms of an asthma or allergic attack. It must be taken regularly for it to be effective.
