Precautions and Warnings for Zaditen® syrup
Zaditen® syrup contains ketotifen
It is important that ketotifen users understand that this medication is not a bronchodilator and should not be used as a rescue medication in acute asthmatic episodes.
Ketotifen will only work properly if it is taken on a regular basis. Sporadic use, or only using the medication when experiencing symptoms, will lead to poor symptom control.
Don't expect ketotifen to start working immediately when therapy is started. Improvement may be seen in the first few weeks of starting the medication, but it may take 10 weeks before any significant improvement can be detected.
Never stop using ketotifen abruptly, especially if symptoms have been partially or completely controlled by the medication. Do not adjust your dosage or discontinue ketotifen without the advise of your doctor.
Drowsiness may occur in the early stages of treatment. This effect often disappears with continued use, but caution should be used when preforming activities requiring rapid and precise responses.
