What generic medicines are available for Zyloprim (allopurinol)?
Zyloprim is the brand name for allopurinol. In most markets, the generic equivalent is allopurinol tablets (commonly available as generics rather than “generic Zyloprim” as a separate product). These generics use the same active ingredient: allopurinol.
Are allopurinol generics the same as Zyloprim?
They are designed to be therapeutically equivalent, meaning they use the same active ingredient (allopurinol) and are intended to provide the same effect. Differences you may see between products are usually things like the manufacturer and inactive ingredients (which can affect appearance or tolerability for some people), not the core medicine.
Is there a “generic Zyloprim” besides allopurinol?
For Zyloprim specifically, the generic pathway is typically through allopurinol (since that is the active drug). Other gout medicines exist, but they are not generics of Zyloprim because they are different drugs.
How can I confirm the exact generic equivalent on my prescription?
Check the prescription label or the medication box for the active ingredient name:
- If it says allopurinol, you have the generic of Zyloprim (or a switch to an allopurinol product).
- If it says allopurinol plus a strength (like mg dosing), match that strength to what your prescriber intended.
What to ask your pharmacist if you’re switching from Zyloprim to a generic?
Ask:
- Whether the generic is the same strength and dosage form
- Whether any recent change was made (brand vs. generic or different manufacturer)
- If you’ve had side effects before, whether the new product has different inactive ingredients
