Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

🎯 Indications and Usage ▾
1 INDICATIONS & USAGE INZIRQO™ (hydrochlorothiazide) is a thiazide diuretic indicated for: The treatment of hypertension in adult and pediatric patients alone or in combination with other antihypertensive agents, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarction (1.1). The treatment of edema associated with congestive heart failure, hepatic cirrhosis and renal disease including the nephrotic syndrome in adult and pediatric patients.
(1.2).
1.1Hypertension INZIRQO is indicated for the treatment of hypertension in adult and pediatric patients, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes., including the class to which this drug principally belongs.
Control of high blood pressure should be part of comprehensive cardiovascular risk management including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC).
Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly.
Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal.
Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy. INZIRQO can be used alone or in combination with other antihypertensive agents.
1.2Edema Treatment of edema associated with congestive heart failure, hepatic cirrhosis, and renal disease including the nephrotic syndrome in adult and pediatric patients.
⏱️ Dosage and Administration ▾
2 DOSAGE & ADMINISTRATION For the treatment of hypertension in adults: The recommended initial dose in adults is 25 mg orally daily given as a single dose.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Monitor kidney function periodically (5.1) Monitor and correct serum electrolytes prior to use and monitor periodically (5.2). Monitor blood sugar, lipid levels, uric acid and calcium levels periodically. (5.3) Exacerbation or activation of systemic lupus erythematosus (5.4) Acute angle-closure glaucoma and acute myopia (5.5)
5.1Impaired Renal Function Monitor kidney function periodically. Diuretics can cause hypovolemia which may precipitate acute kidney injury. Patients with chronic kidney disease, heart failure, or volume depletion may be at particular risk of developing acute renal failure on INZIRQO. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in kidney function while on INZIRQO.
5.2Electrolyte Abnormalities INZIRQO can cause potentially symptomatic hypokalemia, hyponatremia, hypomagnesemia, and hypochloremic alkalosis. Hypomagnesemia can result in hypokalemia which appears difficult to treat despite potassium repletion. Hypokalemia is dose dependent.
Monitor and correct serum electrolytes prior to use and monitor periodically. Discontinue INZIRQO if hypokalemia is associated with clinical symptoms (e.g., ECG changes, muscular weakness).
5.3Metabolic Disturbances INZIRQO may increase blood sugar levels, affect diabetes control, and cause changes in the need for diabetes medication. INZIRQO may raise serum levels of cholesterol and triglycerides. Monitor blood sugar and lipid levels.
INZIRQO may raise the serum uric acid level due to reduced clearance of uric acid and may cause or exacerbate hyperuricemia and precipitate gout in susceptible patients. Increases in serum uric acid are dose related. INZIRQO decreases urinary calcium excretion and may cause elevations of serum calcium.
Monitor calcium levels in patients with hypercalcemia receiving INZIRQO. Discontinue thiazides before carrying out tests for parathyroid function.
5.4Systemic Lupus Erythematosus Thiazide diuretics have been reported to cause exacerbation or activation of systemic lupus erythematosus.
5.5Acute Angle-Closure Glaucoma and Acute Myopia Hydrochlorothiazide, a sulfonamide, can 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. Symptoms include acute onset of decreased visual acuity or ocular pain and typically occur within hours to weeks of drug initiation. Untreated acute angle-closure glaucoma may result in permanent vision loss.
Discontinue drug intake. Consider prompt medical or surgical treatments if the intraocular pressure remains uncontrolled. Risk factors for developing acute angle-closure glaucoma may include a history of sulfonamide or penicillin allergy.

The increased risk for SCC in the overall population was approximately 1 additional case per 16,000 patients per year, and for white patients taking a cumulative dose of ≥ 50,000 mg the risk increase was approximately 1 additional SCC case for every 6,700 patients per year.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS NSAID: May lead to increased risk of renal impairment and loss of diuretic and antihypertensive effect (7.1). Cholestyramine and colestipol: Reduced absorption of thiazides (7.1) Lithium: Increased lithium concentrations and lithium toxicity (7.2) Antidiabetic drugs: Dosage adjustment of antidiabetic may be required (7.2)
7.1Potential for Other Drugs to Affect INZIRQO Non-Steroidal Anti-Inflammatory Agents: Administration of a nonsteroidal anti-inflammatory agent, including a selective COX-2 inhibitor can reduce the diuretic, natriuretic, and antihypertensive effects of thiazide diuretics. Therefore, when INZIRQO and nonsteroidal anti-inflammatory agents are used concomitantly, check to determine if the desired effect of the diuretic is obtained. Cholestyramine and Colestipol : Absorption of hydrochlorothiazide is impaired in the presence of anionic exchange resins.
Stagger the dosage of INZIRQO and the resin such that INZIRQO is administered at least 4 hours before or 4 to 6 hours after the administration of the resin.
7.2Potential for INZIRQO to Affect Other Drugs Lithium: Increases in serum lithium concentrations and lithium toxicity have been reported during concomitant administration of hydrochlorothiazide. Monitor serum lithium levels during concomitant use and adjust the lithium dose during concomitant administration or discontinuation of hydrochlorothiazide. Antidiabetic Drugs (oral agents and insulin): Dosage adjustment of the antidiabetic drug may be required when coadministered with hydrochlorothiazide.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Untreated hypertension during pregnancy can lead to adverse outcomes for the mother and the fetus (see Clinical Considerations). Available data from published observational studies have not demonstrated a drug-associated risk of major birth defects, miscarriage or adverse maternal outcomes with hydrochlorothiazide use during pregnancy. However, there have been rare reports of jaundice, thrombocytopenia, and electrolyte imbalances in infants exposed to thiazide medications during pregnancy.
The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Hypertension in pregnancy increases the maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section, and post-partum hemorrhage).
Hypertension increases the fetal risk for intrauterine growth restriction and intrauterine death. Monitor pregnant women with hypertension. Data Animal Data Teratogenic effects: Studies in which hydrochlorothiazide was orally administered to pregnant mice and rats during their respective periods of major organogenesis at doses up to 3000 and 1000 mg hydrochlorothiazide /kg (approximately 146-fold and 97-fold the maximum recommended human dose based on body surface area), respectively, provided no evidence of harm to the fetus.
8.2Lactation Risk Summary Available data from published literature indicate hydrochlorothiazide is present in human milk (see Data) . There are no reports of adverse effects on breastfed infants exposed to hydrochlorothiazide during lactation. Doses of hydrochlorothiazide associated with clinically significant diuresis have been associated with impaired milk production.
Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for INZIRQO and any potential adverse effects on the breastfed infant from INZIRQO or from the underlying maternal condition. Data A single study involving one woman and her infant showed a peak concentration of 275 mcg/L at 3 hours following 50 mg dose. No drug was detected (<20 mcg/L) in the infant’s plasma at 2 and 11 hours following the mother’s dose.
8.4Pediatric Use INZIRQO is approved for use in pediatric patients for the following: Treatment of hypertension to lower blood pressure Treatment of edema associated with congestive heart failure, hepatic cirrhosis, and renal disease, including the nephrotic syndrome
8.5Hepatic Impairment Monitor for mental status changes when using INZIRQO in patients with hepatic impairment because fluid shifts may precipitate hepatic coma.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Thiazides affect the renal tubular mechanisms of electrolyte reabsorption, directly increasing excretion of sodium and chloride in approximately equivalent amounts. Indirectly, the diuretic action of hydrochlorothiazide reduces plasma volume, with consequent increases in plasma renin activity, increases in aldosterone secretion, increases in urinary potassium loss, and decreases in serum potassium. The mechanism of the antihypertensive effect of thiazides is not fully understood.
12.2Pharmacodynamics Hydrochlorothiazide does not usually affect normal blood pressure. Hydrochlorothiazide affects the distal renal tubular mechanism of electrolyte reabsorption. At maximal therapeutic dosage, all thiazides are approximately equal in their diuretic efficacy.
Hydrochlorothiazide increases excretion of sodium and chloride in approximately equivalent amounts. Natriuresis may be accompanied by some loss of potassium and bicarbonate. After oral use, diuresis begins within 2 hours, peaks in about 4 hours and lasts about 6 to 12 hours.
12.3Pharmacokinetics Over a dose range of 50 to 100 mg, peak plasma hydrochlorothiazide concentrations and exposure (AUC) of INZIRQO increases proportionally with dose in healthy subjects. Absorption Following single-dose oral administration of 100 mg INZIRQO to healthy subjects in the fasted state, the AUC and C max of hydrochlorothiazide was 5940 ng.h/mL and 972 ng/mL, respectively. The peak plasma hydrochlorothiazide concentrations are achieved at approximately 1.5 hours.
Effect of Food: A food-effect study involving administration of INZIRQO to healthy male and female subjects after a high-fat, high calorie breakfast indicated that the rate of absorption (C max ) decreased 38%, while the extent of absorption (AUC) remained unchanged, when compared to administration under fasting conditions. The T max was delayed by 2 hours. Cholestyramine and Colestipol Resins: Absorption of hydrochlorothiazide is impaired in the presence of anionic exchange resins.
Single doses of either cholestyramine or colestipol resins reduced the bioavailability of hydrochlorothiazide by up to 85% and 43%, respectively. Distribution Hydrochlorothiazide binds to albumin (40% to 70%) and distributes into erythrocytes. It crosses the placental but not the blood-brain barrier and is excreted in breast milk.
Elimination Following oral administration of INZIRQO, plasma hydrochlorothiazide concentrations decline biexponentially, with a terminal elimination half-life of about 10 hours. At least 61% of the oral dose is eliminated unchanged in the urine within 24 hours.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Acute Angle-Closure Glaucoma and Acute Myopia Advise patients to discontinue INZIRQO and seek immediate medical attention if they experience symptoms of Acute Myopia or Secondary Angle-Closure Glaucoma [see Warnings and Precautions (5.5)] . Non-melanoma Skin Cancer Instruct patients taking hydrochlorothiazide to protect skin from the sun and undergo regular skin cancer screening [see Postmarketing Experience (6.2)]. Recommended Administration Advise patients to always shake the bottle well before each use and measure the dose using a calibrated oral dosing syringe to ensure that the dose is measured and administered accurately.
Inform patients that a bottle adapter and oral dosing syringes may be obtained from their pharmacy. Advise patients never to use household teaspoons or tablespoons to measure INZIRQO. Advise patients that the oral suspension should be stored at room temperature (20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F)).
INZIRQO may be taken with or without meals. Discard any unused suspension 30 days after reconstitution. Trademarks are the property of their respective owners.

🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Over a dose range of 50 to 100 mg, peak plasma hydrochlorothiazide concentrations and exposure (AUC) of INZIRQO increases proportionally with dose in healthy subjects. Absorption Following single-dose oral administration of 100 mg INZIRQO to healthy subjects in the fasted state, the AUC and C max of hydrochlorothiazide was 5940 ng.h/mL and 972 ng/mL, respectively. The peak plasma hydrochlorothiazide concentrations are achieved at approximately 1.5 hours.
Effect of Food: A food-effect study involving administration of INZIRQO to healthy male and female subjects after a high-fat, high calorie breakfast indicated that the rate of absorption (C max ) decreased 38%, while the extent of absorption (AUC) remained unchanged, when compared to administration under fasting conditions. The T max was delayed by 2 hours. Cholestyramine and Colestipol Resins: Absorption of hydrochlorothiazide is impaired in the presence of anionic exchange resins.
Single doses of either cholestyramine or colestipol resins reduced the bioavailability of hydrochlorothiazide by up to 85% and 43%, respectively. Distribution Hydrochlorothiazide binds to albumin (40% to 70%) and distributes into erythrocytes. It crosses the placental but not the blood-brain barrier and is excreted in breast milk.
Elimination Following oral administration of INZIRQO, plasma hydrochlorothiazide concentrations decline biexponentially, with a terminal elimination half-life of about 10 hours. At least 61% of the oral dose is eliminated unchanged in the urine within 24 hours.
🧬 Pharmacodynamics ▾
12.2Pharmacodynamics Hydrochlorothiazide does not usually affect normal blood pressure. Hydrochlorothiazide affects the distal renal tubular mechanism of electrolyte reabsorption. At maximal therapeutic dosage, all thiazides are approximately equal in their diuretic efficacy.
Hydrochlorothiazide increases excretion of sodium and chloride in approximately equivalent amounts. Natriuresis may be accompanied by some loss of potassium and bicarbonate. After oral use, diuresis begins within 2 hours, peaks in about 4 hours and lasts about 6 to 12 hours.
🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis & Mutagenesis & Impairment Of Fertility Two year feeding studies in mice and rats conducted under the auspices of the National Toxicology Program (NTP) uncovered no evidence of a carcinogenic potential of hydrochlorothiazide in female mice (at doses of up to approximately 600 mg/kg/day) or in male and female rats (at doses of up to approximately 100 mg/kg/day). The NTP, however, found equivocal evidence for hepatocarcinogenicity in male mice. Hydrochlorothiazide was not genotoxic in vitro in the Ames mutagenicity assay of Salmonella typhimurium strains TA 98, TA 100, TA 1535, TA 1537, and TA 1538 and in the Chinese Hamster Ovary (CHO) test for chromosomal aberrations, or in vivo in assays using mouse germinal cell chromosomes, Chinese hamster bone marrow chromosomes, and the Drosophila sex-linked recessive lethal trait gene.
Positive test results were obtained only in the in vitro CHO Sister Chromatid Exchange (clastogenicity)and in the Mouse Lymphoma Cell (mutagenicity) assays, using concentrations of hydrochlorothiazide from 43 to 1300 mcg/mL, and in the Aspergillus nidulans nondisjunction assay at an unspecified concentration.
