Zileuton tablets and extended-release tablets contain the same amount of the drug, but they are not taken in the same way. Follow your doctor's instructions.

Zileuton extended-release tablets are usually taken twice daily, within 1 hour after your morning and evening meals.
Do not crush, chew, or break an extended-release tablet. Swallow it whole. Breaking the pill may cause too much of the drug to be released at one time.
Do not use zileuton to treat an asthma attack that has already begun. It will not work fast enough. Use only a fast acting inhalation medication. Talk with your doctor if any of your asthma medications do not seem to work as well in treating or preventing attacks.
It may take up to a few weeks before your symptoms improve. Keep using the medication as directed even if you feel fine or have no symptoms. Having no asthma symptoms is a sign that the medication is working.
Asthma is often treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice, even if you have no asthma symptoms.
