DOSAGE MUST BE INDIVIDUALIZED ACCORDING TO PATIENT’S RESPONSE.
CAPOZIDE may be substituted for the previously titrated individual components.
Alternatively, therapy may be instituted with a single tablet of CAPOZIDE 25 mg/15 mg taken once daily. For patients insufficiently responsive to the initial dose, additional captopril or hydrochlorothiazide may be added as individual components or by using CAPOZIDE 50 mg/15 mg, 25 mg/25 mg or 50 mg/25 mg, or divided doses may be used.
Because the full effect of a given dose may not be attained for six to eight weeks, dosage adjustments should generally be made at six-week intervals, unless the clinical situation demands more rapid adjustment.
In general, daily doses of captopril should not exceed 150 mg and of hydrochlorothiazide should not exceed 50 mg.
CAPOZIDE should be taken one hour before meals.
Dosage Adjustment in Renal Impairment: Because captopril and hydrochlorothiazide are excreted primarily by the kidneys, excretion rates are reduced in patients with impaired renal function. These patients will take longer to reach steady-state captopril levels and will reach higher steady-state levels for a given daily dose than patients with normal renal function. Therefore, these patients may respond to smaller or less frequent doses of CAPOZIDE.
After the desired therapeutic effect has been achieved, the dose intervals should be increased or the total daily dose reduced until the minimal effective dose is achieved. When concomitant diuretic therapy is required in patients with severe renal impairment, a loop diuretic (eg, furosemide), rather than a thiazide diuretic is preferred for use with captopril; therefore, for patients with severe renal dysfunction the captopril and hydrochlorothiazide combination tablet is not usually recommended. (See WARNINGS: Captopril: Anaphylactoid and Possibly Related Reactions: Anaphylactoid reactions during membrane exposure and PRECAUTIONS: Hemodialysis.)
