Calcium nephrolithiasis (off-label use): Oral: 2.5 mg once daily (Ref).
Edema or general volume overload (adjunctive to loop diuretic):
Note: Optimize loop diuretic therapy before adding indapamide; combination diuretic therapy is typically for short-term use to restore euvolemia in patients already taking high-dose loop diuretic therapy who are resistant (eg, furosemide total daily dose of 160 to 320 mg/day IV or equivalent). Combination diuretic therapy can cause severe electrolyte depletion (eg, potassium, magnesium, sodium); prior to and during therapy, electrolytes should be monitored and appropriately managed (Ref).
Oral: Initial: 2.5 mg once daily; may increase dose, as needed, up to 5 mg once daily depending on patient response; may administer every other day or on specific days of the week; may be administered in combination with or shortly before the scheduled loop diuretic. Assess volume status frequently (eg, daily or at least every 2 to 3 days) to determine effectiveness and avoid over-diuresis. Continue until euvolemia is restored, although some patients may require scheduled treatment for maintenance (Ref).
Hypertension, chronic:
Note: For patients who warrant combination therapy (BP >20/10 mm Hg above goal or suboptimal response to initial monotherapy), may use in combination with another appropriate agent (eg, angiotensin-converting enzyme inhibitor, angiotensin II receptor blocker, dihydropyridine calcium channel blocker) (Ref); however, some experts prefer regimens that do not include thiazide diuretics for combination therapy (Ref).
Oral: Initial: 1.25 to 2.5 mg once daily; evaluate response after ~2 to 4 weeks and titrate dose as needed; doses >2.5 mg/day are generally not recommended due to greater risk for adverse effects with minimal added antihypertensive benefit; if additional blood pressure control is needed, consider combination therapy. Patients with severe asymptomatic hypertension and no signs of acute end organ damage should be evaluated for medication titration within 1 week (Ref).
The renal dosing recommendations are based upon the best available evidence and clinical expertise. Senior Editorial Team: Bruce Mueller, PharmD, FCCP, FASN, FNKF; Jason A. Roberts, PhD, BPharm (Hons), B App Sc, FSHP, FISAC; Michael Heung, MD, MS.
Altered kidney function:
eGFR ≥30 mL/minute/1.73 m2: No dosage adjustment necessary (Ref).
eGFR <30 mL/minute/1.73 m2: No dosage adjustment necessary. The diuretic effect may become diminished as kidney function declines, but small, short-term studies suggest hypertensive benefit may be preserved (Ref).
Augmented renal clearance (measured urinary CrCl ≥130 mL/minute/1.73 m2): Augmented renal clearance (ARC) is a condition that occurs in certain critically ill patients without organ dysfunction and with normal serum creatinine concentrations. Younger patients (<55 years of age) admitted post trauma or major surgery are at highest risk for ARC, as well as those with sepsis, burns, or hematologic malignancies. An 8- to 24-hour measured urinary CrCl is necessary to identify these patients (Ref).
No dosage adjustment necessary (Ref).
Hemodialysis, intermittent (thrice weekly): Not significantly dialyzable: Dose as if eGFR <30 mL/minute/1.73 m2 (Ref).
Peritoneal dialysis: Unlikely to be significantly dialyzable: Dose as if eGFR <30 mL/minute/1.73 m2 (Ref).
CRRT: Dose as if eGFR <30 mL/minute/1.73 m2 (Ref).
PIRRT (eg, sustained, low-efficiency diafiltration): Dose as if eGFR <30 mL/minute/1.73 m2 (Ref).

Hypersensitivity to indapamide or any component of the formulation or sulfonamide-derived drugs; anuria.
Note: Although the FDA-approved product labeling states this medication is contraindicated in patients with hypersensitivity to sulfonamide-containing drugs, the scientific basis of this cross-sensitivity has been challenged.
Canadian labeling: Additional contraindications (not in US labeling): Severe renal failure (CrCl <30 mL/minute); hepatic encephalopathy; severe hepatic impairment; hypokalemia; concomitant use with antiarrhythmic agents causing torsade de pointes; pregnancy; breastfeeding; hereditary problems of galactose intolerance, glucose-galactose malabsorption, or total lactase deficiency.
Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Concerns related to adverse effects:
• Electrolyte disturbances: Severe hyponatremia with hypokalemia has been reported at recommended doses (particularly in elderly women); risk may be dose dependent, therefore, use lowest dose possible. Hypochloremic alkalosis, hypomagnesemia, or hypercalcemia can also occur; monitor electrolytes periodically during therapy.
• Ocular effects: Sulfonamide or sulfonamide derivatives, including indapamide, may cause an idiosyncratic reaction resulting in acute angle-closure glaucoma and elevated intraocular pressure with or without a noticeable acute myopic shift and/or choroidal effusions. Symptom onset (eg, decreased visual acuity, ocular pain) typically occurs within hours to weeks after treatment initiation and may result in permanent vision loss if left untreated. Risk may be increased in patients with sulfonamide or penicillin allergy.
• Sulfonamide (“sulfa”) allergy: The FDA-approved product labeling for many medications containing a sulfonamide chemical group includes a broad contraindication in patients with a prior allergic reaction to sulfonamides. There is a potential for cross-reactivity between members of a specific class (eg, two antibiotic sulfonamides). However, concerns for cross-reactivity have previously extended to all compounds containing the sulfonamide structure (SO2NH2). An expanded understanding of allergic mechanisms indicates cross-reactivity between antibiotic sulfonamides and nonantibiotic sulfonamides may not occur or at the very least this potential is extremely low (Brackett 2004; Johnson 2005; Slatore 2004; Tornero 2004). In particular, mechanisms of cross-reaction due to antibody production (anaphylaxis) are unlikely to occur with nonantibiotic sulfonamides. T-cell-mediated (type IV) reactions (eg, maculopapular rash) are less well understood and it is not possible to completely exclude this potential based on current insights. In cases where prior reactions were severe (Stevens-Johnson syndrome/TEN), some clinicians choose to avoid exposure to these classes.
Disease-related concerns:
• Adrenal insufficiency: Avoid use of diuretics for treatment of elevated blood pressure in patients with primary adrenal insufficiency (Addison disease). Adjustment of glucocorticoid/mineralocorticoid therapy and/or use of other antihypertensive agents is preferred to treat hypertension (Bornstein 2016; Inder 2015).
• Bariatric surgery: Dehydration: Avoid diuretics in the immediate postoperative period after bariatric surgery; electrolyte disturbances and dehydration may occur. Diuretics may be resumed, if indicated, once oral fluid intake goals are met (Ziegler 2009).
• Diabetes: Use with caution in patients with prediabetes or diabetes mellitus; may see a change in glucose control.
• Gout: In certain patients with a history of gout, a familial predisposition to gout, or chronic renal failure, gout can be precipitated.
• Hepatic impairment: Use with caution in patients with severe hepatic dysfunction; in cirrhosis, avoid electrolyte and acid/base imbalances that might lead to hepatic encephalopathy.
• Hypercholesterolemia: Use with caution in patients with moderate or high cholesterol concentrations; thiazide diuretics have been shown to increase cholesterol concentrations; however, indapamide (a thiazide-like diuretic) has not been shown to adversely affected lipids.
• Hypokalemia: Use with caution in patients with hypokalemia; correct before initiating therapy.
• Kidney impairment: Use with caution in severe kidney disease.
• Systemic lupus erythematosus: Can cause systemic lupus erythematosus exacerbation or activation.
Dosage forms specific issues:
• Lactose: Formulation may contain lactose.

When diuretics are used for the treatment of heart failure in patients planning to become pregnant, adjust dose prior to conception to minimize risk of placental hypoperfusion (AHA/ACC/HFSA [Heidenreich 2022]); agents other than indapamide may be preferred (ESC [Regitz-Zagrosek 2018]).
Medications considered acceptable for the treatment of chronic hypertension during pregnancy may generally be continued in patients trying to conceive. Diuretics are second-line agents for the treatment of hypertension in pregnant patients (ACC/AHA [Whelton 2018]; ACOG 2019; NICE 2019; SOGC [Magee 2022]).
Diuretics cross the placenta and are found in cord blood.
Maternal use may cause fetal or neonatal jaundice, thrombocytopenia, or other adverse events observed in adults.
Chronic maternal hypertension is also associated with adverse events in the fetus/infant. Chronic maternal hypertension may increase the risk of birth defects, low birth weight, premature delivery, stillbirth, and neonatal death. Actual fetal/neonatal risks may be related to the duration and severity of maternal hypertension. Untreated chronic hypertension may also increase the risks of adverse maternal outcomes, including gestational diabetes, preeclampsia, delivery complications, stroke, and myocardial infarction (ACOG 2019).
Use of thiazide diuretics during pregnancy may be considered to treat edema due to pathologic causes (as in the nonpregnant patient); monitor.
Patients with preexisting hypertension may continue their medication during pregnancy unless contraindications exist (ESC [Regitz-Zagrosek 2018]). Diuretics are second-line agents for the treatment of hypertension in pregnant patients (ACOG 2019; SOGC [Magee 2022]); however, data related to the use of indapamide in pregnancy are insufficient and other agents may be preferred (ESC [Regitz-Zagrosek 2018]).
Heart failure in pregnancy is associated with adverse maternal and fetal outcomes, including premature birth, infants born small for gestational age, and increased risk of maternal and fetal death (Bright 2021). Thiazide diuretics may be used for symptom management in pregnant patients with heart failure complicated by pulmonary congestion; closely monitor volume status and adjust dose to minimize risk of placental hypoperfusion (AHA/ACC/HFSA [Heidenreich 2022]; ESC [Regitz-Zagrosek 2018]); however, data related to the use of indapamide in pregnancy are insufficient and other agents may be preferred (ESC [Regitz-Zagrosek 2018]).
It is not known if indapamide is present in breast milk.
If indapamide is needed, the manufacturer recommends that breastfeeding be discontinued.
May be taken without regard to meals (Caruso 1983); however, administration with food or milk may to decrease GI adverse effects.

Diuretic effect is localized at the proximal segment of the distal tubule of the nephron; it does not appear to have significant effect on glomerular filtration rate nor renal blood flow; like other diuretics, it enhances sodium, chloride, and water excretion by interfering with the transport of sodium ions across the renal tubular epithelium
