ZILEUTON - ORAL

(zye-LOO-ton)

COMMON BRAND NAME(S): Zyflo

USES: This medication is used to control long-term (chronic) asthma and help decrease the number of asthma attacks. Controlling asthma can decrease time lost from work or school. This drug improves asthma symptoms by blocking substances in the body called leukotrienes. It will not treat a sudden asthma attack.

The manufacturer does not recommend the use of zileuton for children under 12 years old due to the risk of liver problems.

HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using zileuton and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth with or without food, usually 4 times daily or as directed by your doctor.

Continue taking this drug as directed, even during sudden asthma attacks. Do not stop taking this medication unless directed to do so by your doctor. Do not take more than the prescribed dose. Also, do not decrease the dose or stop taking any other asthma medication unless directed to do so by your doctor.

Use this medication regularly to get the most benefit from it, even during asthma attacks and periods when you have no asthma symptoms. To help you remember, take it at the same times each day.

Seek immediate medical attention if your asthma symptoms worsen, if you notice that you are using more of your quick-relief inhaler (e.g., albuterol, salbutamol), or if you need to use the quick-relief inhaler more than the maximum number of times prescribed in 24 hours.
