Why is this medication prescribed?

Zyflo (zileuton) is a prescription medication used to treat asthma. It belongs to a class of drugs known as leukotriene synthesis inhibitors. Leukotrienes are substances in the body that can cause inflammation and constriction of the airways, leading to asthma symptoms.

How should this medicine be used?

Here are some key points about Zyflo:

  • Indications: Zyflo is typically prescribed for the prevention and long-term control of asthma symptoms in adults and children who are at least 12 years old. It is not used for the relief of acute bronchospasm (sudden and severe shortness of breath).
  • Mechanism of Action: Zyflo works by inhibiting the production of leukotrienes. Leukotrienes play a role in the inflammatory process in the airways, and by blocking their synthesis, Zyflo helps reduce inflammation and bronchoconstriction.
  • Dosage: The dosage of Zyflo can vary depending on the patient’s age and other individual factors. It is usually taken four times a day, with or without food. The medication is available in tablet form.
  • Usage Instructions: It’s important to take Zyflo exactly as prescribed by your healthcare provider. Do not adjust the dosage or stop taking the medication without consulting your doctor.
  • Monitoring: While taking Zyflo, your healthcare provider may monitor your liver function regularly because the drug can affect liver enzymes.
  • Side Effects: Like any medication, Zyflo can cause side effects. Common side effects may include headache, nausea, pain or fullness in the ears, and trouble sleeping. Serious side effects are rare but may include liver problems. If you experience any unusual or severe side effects, you should contact your healthcare provider.
  • Precautions: Inform your doctor about any other medications you are taking, including over-the-counter drugs and herbal supplements, as they may interact with Zyflo. Also, let your healthcare provider know if you have a history of liver problems.

It’s crucial to follow your healthcare provider’s instructions and attend regular check-ups while taking Zyflo to monitor its effectiveness and address any potential side effects or concerns. Always consult with your doctor or healthcare professional for personalized advice regarding your specific health condition and treatment plan.
