Zafirlukast is usually taken orally, twice daily or as directed by a healthcare professional. The dosage is based on the patient's medical condition and response to treatment.
Side Effects
Common side effects of Zafirlukast include headache, nausea, and diarrhea. Serious side effects are rare but may include liver disease, mood changes, and difficulty sleeping.
Precautions
Before taking Zafirlukast, patients should inform their healthcare provider if they have any allergies or a history of liver disease. It is also important to discuss the risks and benefits of Zafirlukast during pregnancy and breastfeeding.
Interactions
Zafirlukast may interact with other medications such as warfarin and theophylline. Therefore, it is crucial to inform the healthcare provider of all the products the patient is using.
