Is there a generic for chlorthalidone?

Is there a generic version of chlorthalidone?

Yes. Chlorthalidone (also spelled chlorothalidone in some references, and commonly written as chlorthalidone) has generic versions available.

Why you might be seeing different names (chlorthalidone vs chlorothiazide vs chlorthalidone)

People sometimes mix up:
- Chlorthalidone/chlorothalidone: a thiazide-like diuretic (spelling varies by source and product label).
- Chlorothiazide: a different medication.
If you’re checking for a generic, make sure the active ingredient on the package label matches the exact spelling your prescription uses.

How to check the right generic for your prescription

Look for “chlorthalidone” as the active ingredient on the prescription or bottle, then search the generic by that name (or confirm the National Drug Code on the label, if you have it).

What if you meant chlorothalidone/chlorothiazide instead?

If you tell me the exact spelling on the prescription (and the strength, like 12.5 mg or 25 mg), I can help you confirm whether a generic exists for that specific drug and strength.
