Candesartan / Hydrochlorothiazide Dosage

Medically reviewed by Drugs.com. Last updated on Jan 31, 2024.

Usual Adult Dose for Hypertension

Candesartan 16 to 32 mg-Hydrochlorothiazide 12.5 to 50 mg orally daily in 1 to 2 divided doses

Comments:

• The recommended starting dose of candesartan is 16 mg orally once a day when used as monotherapy in patients who are not volume depleted; doses larger than 32 mg do not appear to have a greater blood pressure lowering effect.
• A patient whose blood pressure remains uncontrolled on candesartan 32 mg can expect an incremental effect from candesartan 32 mg-hydrochlorothiazide 12.5 mg
• A patient whose blood pressure remains uncontrolled on hydrochlorothiazide 25 mg can expect an incremental effect from candesartan 16 mg-hydrochlorothiazide 12.5 mg; a patient whose blood pressure is controlled on hydrochlorothiazide 25 mg but is experiencing decreases in serum potassium can expect the same or incremental blood pressure effects from candesartan 16 mg-hydrochlorothiazide 12.5 mg and serum potassium may improve.
• Maximal antihypertensive effect can be expected within 4 weeks of treatment initiation.
