Lisinopril hctz maximum dosage?

The maximum daily dose depends on the exact lisinopril/hydrochlorothiazide (HCTZ) product, but the general upper limit for this combination is:

- Lisinopril: up to 40 mg per day
- HCTZ: up to 25 mg per day (for hypertension)

So the typical maximum for the fixed-dose combo is 40 mg lisinopril with 25 mg HCTZ per day. This can be given as one tablet of 40/25 mg (if that strength exists) or as two tablets of a lower-strength tablet (e.g., two 20/12.5 mg tablets) to total 40/25 mg.

If you can share the exact product name or the tablet strengths you’re using, I can confirm the exact maximum dose for that brand. And as always, follow your prescription label and your clinician’s guidance.
