Is allopurinol a generic drug?

Is allopurinol available as a generic?

Yes. Allopurinol is a widely available generic medicine, with many brands selling the same active ingredient (allopurinol) in different strengths and formulations.

Why does it show up under different brand names?

Brands can differ, but the drug is the same at the active-ingredient level. For patients, this usually means the main differences you may notice are the manufacturer, pill strength, and inactive ingredients—not the drug’s core effects.

Are there any “non-generic” versions of allopurinol?

Allopurinol itself is not treated as a single-brand, exclusivity-only product in routine use; it is marketed as a generic by multiple manufacturers. If a product label shows “allopurinol” as the active ingredient, it is generally a generic form regardless of the brand name.

What should you check on a prescription or pharmacy label?

Look at the active ingredient line. If it says “allopurinol” (e.g., “allopurinol tablets”), it is the generic medication. If you share the exact product name and strength on your label, I can help confirm what it corresponds to.
