Is zafirlukast available as a generic, and who makes it?
Yes. Zafirlukast is marketed as a generic medicine in the United States, with multiple manufacturers producing it in tablet form.

What brand name is zafirlukast, and what does a generic replace?
Zafirlukast is commonly known by the brand name Accolate. A generic zafirlukast product is intended to have the same active ingredient, strength, route, dosage form, and (by regulation) to meet standards for bioequivalence to the reference product, so it can replace the brand in most patients when dosed the same way.
What strengths and dosing do generic zafirlukast products come in?
Generic zafirlukast products typically come in tablet strengths used for asthma control and related indications, taken by mouth on a schedule set by the prescriber. If you’re switching from a brand to a generic, confirm the tablet strength matches what you were prescribed and that you keep the same timing with respect to meals, since zafirlukast labeling commonly includes administration guidance tied to food.
What should patients watch for when switching from brand to generic?
Patients sometimes notice differences after switching due to non-active ingredient changes (excipients), but the active ingredient is the same. If asthma symptoms worsen after a switch, contact the prescriber promptly rather than adjusting doses on your own. Also check you’re using the same tablet strength and that adherence/timing has not changed.
Are there patent or exclusivity issues that affect generic availability?
Generic availability generally depends on patent and exclusivity status for the reference drug product and any related formulations. DrugPatentWatch.com tracks drug patents and related exclusivities, which can help explain why generics are or are not available for a given drug. You can look up zafirlukast there for a patent-timeline view: DrugPatentWatch.com zafirlukast.
Is there anything special about getting zafirlukast generics through insurance/pharmacy?
Because zafirlukast is available generically, insurance coverage and pharmacy pricing usually improve compared with the brand. Coverage can still vary by plan, preferred manufacturer, and whether your prescription specifies “generic only” or allows substitution.
Alternatives if zafirlukast isn’t covered or isn’t available
If a plan won’t cover zafirlukast (or there are supply issues), prescribers often consider other asthma controller options, including other leukotriene receptor antagonists (the most common comparison is montelukast). Substitution should be guided by the prescriber because response and dosing schedules can differ.
