Competitively inhibits ACE, preventing the conversion of angiotensin I to angiotensin II, reversing the potassium loss associated with the diuretic.Hydrochlorothiazide
Increases chloride, sodium, and water excretion by interfering with transport of sodium ions across renal tubular epithelium.
Indications and Usage
For the treatment of hypertension.
History of angioedema related to previous treatment with an ACE inhibitor; hereditary or idiopathic angioedema; anuria; hypersensitivity to sulfonamide-derived drugs or hypersensitivity to any component of the product.
Dosage and AdministrationAdults

Not recommended when CrCl is less than 30 mL/min.
- Administer with or without food.
- The combination may be substituted for the titrated individual components.
- Not indicated for initial therapy of hypertension.
Store between 59° and 86°F. Protect from excessive light and moisture.
No drug interaction studies have been conducted between lisinopril/hydrochlorothiazide and other drugs. The following interactions are based on drug interactions involving each component of the lisinopril/hydrochlorothiazide combination.Lisinopril Aldosterone blockers (eg, eplerenone)
May cause serious hyperkalemia, possibly with cardiac arrhythmias. Monitor potassium level periodically and reduce dose of aldosterone blocker if needed.Aliskiren
May decrease renal excretion of potassium. Closely monitor serum potassium.Angiotensin II receptor antagonists (eg, valsartan)
Increased risk of renal dysfunction and hyperkalemia. Closely monitor renal function and serum potassium.Clozapine
May cause excessive decreases in BP and syncope. Consider lower starting dosage of clozapine.Cyclooxygenase 2 inhibitors (eg, celecoxib)
May result in deterioration of renal function, including acute renal failure. Monitor renal function, particularly in patients who are elderly or volume-depleted, or those with impaired renal function.Cyclosporine
Renal failure has been reported with cyclosporine and ACE inhibitor administration. If renal dysfunction occurs, it may be necessary to stop one or both agents.Gold
Nitroid reactions (symptoms include facial flushing, nausea, vomiting, and hypotension) may occur in patients using injectable gold (sodium aurothiomalate).Ketorolac (nasal)
May cause decreased antihypertensive effects. Monitor BP closely. If BP control deteriorates, consider stopping ketorolac (nasal).mTOR inhibitors (eg, everolimus, sirolimus)
Increased risk of angioedema ranging from minor facial edema to life-threatening mouth and throat swelling may occur. If an interaction is suspected, stop one or both drugs.Pergolide
May cause hypotension. Start with lower doses of pergolide and monitor BP closely. If BP falls, dosage reduction may be needed.Phenothiazines
May produce a synergistic hypotensive effect with postural syncope. Monitor BP (supine and standing) and adjust dosage of antihypertensive as needed.Potassium preparations, potassium-sparing diuretics
May significantly increase serum potassium levels. Hyperkalemia, possibly with cardiac arrhythmias or arrest, may occur. Closely monitor serum potassium concentrations.Salicylates (eg, aspirin, bismuth salicylate)
Hypotensive effects may be decreased. Adjust dosage of antihypertensive as needed. May need to stop salicylates if BP control or renal function deteriorates.Tizanidine
May cause severe hypotension. Monitor BP.Trimethoprim
May cause hyperkalemia and possibly cardiac arrhythmias. Closely monitor serum potassium.Hydrochlorothiazide Adrenocorticotropic hormones, corticosteroids
Electrolyte depletion may be intensified, particularly hypokalemia. Laboratory monitoring is warranted.Alcohol, barbiturates, narcotics
Potentiation of orthostatic hypotension may occur. Monitor BP.Antihypertensive agents
Additive or potentiation of hypotension effects. Closely monitor BP.Antineoplastic agents (eg, cyclophosphamide)
Hydrochlorothiazide may prolong antineoplastic-induced myelosuppression. Use with caution.Cholestyramine, colestipol resins
Hydrochlorothiazide absorption may be impaired. Single doses of cholestyramine or colestipol resins bind hydrochlorothiazide, reducing GI absorption up to 85% and 43%, respectively. Separate the administration times by as much as possible.Diazoxide
The pharmacologic effects of both drugs may be increased. Hyperglycemia, hyperuricemia, and hypotension may occur. Closely monitor BP, blood glucose, and serum uric acid.Digoxin
Hydrochlorothiazide-induced electrolyte disturbances may predispose to digitalis-induced arrhythmias. Measure plasma concentrations of potassium and magnesium; supplement low levels. Prevent further losses with dietary management.Dofetilide
Dofetilide plasma concentrations may be increased. Prolongation of the QT interval may occur, increasing the risk of torsades de pointes. Coadministration of hydrochlorothiazide and dofetilide is contraindicated.Hypoglycemic agents, oral (eg, sulfonylureas)
Hydrochlorothiazide may increase fasting blood glucose and decrease insulin secretion. The effect of oral hypoglycemic agents and insulin may be decreased. Monitor blood glucose and adjust the hypoglycemic dose as needed.Insulin
Hydrochlorothiazide may increase fasting blood glucose and decrease insulin secretion. The effect of insulin may be decreased. Monitor blood glucose and adjust the insulin dose as needed.Lithium
Lithium clearance may be decreased, increasing lithium concentrations and the risk of lithium toxicity. Lithium generally should not be given with diuretics.Loop diuretics (eg, furosemide)
May cause diuresis and serious electrolyte abnormalities. Monitor for dehydration and electrolyte abnormalities during combined therapy.Nondepolarizing muscle relaxants (eg, tubocurarine)
Possible increased responsiveness to the muscle relaxant due to diuretic-induced hypokalemia. If hypokalemia cannot be corrected, a lower dosage of nondepolarizing muscle relaxants may be needed.NSAIDs (eg, ibuprofen, indomethacin)
The diuretic, natriuretic, and antihypertensive effects of hydrochlorothiazide may be reduced. Monitor BP and the diuretic response. Additional monitoring of renal function may be needed in elderly or volume-depleted patients or in those who have decreased renal function.Pressor amines (eg, norepinephrine)
Response to pressor amines may be decreased. Use with caution.Tretinoin
The risk of phototoxicity may be increased if these agents are coadministered. Avoid coadministration.

When used in pregnancy during the second and third trimesters, ACE inhibitors can cause injury and even death to the developing fetus. When pregnancy is detected, discontinue therapy as soon as possible.
Observe all patients for signs of fluid or electrolyte imbalance (eg, hyponatremia, hypochloremic, alkalosis, hypokalemia, hyperkalemia, hypomagnesemia). Periodically determine serum electrolytes at appropriate intervals, including potassium, BUN, and serum creatinine, especially when therapy is initiated or dosage adjusted. Periodically monitor WBC in patients with collagen vascular disease and renal disease. Monitor blood sugar in patients with diabetes when lisinopril/hydrochlorothiazide is started or the dose is changed. Monitor and record BP and pulse.
Category D (second and third trimesters); Category C (first trimester). Lisinopril can cause fetal and neonatal morbidity and death when administered to pregnant women. Do not use during pregnancy.
Undetermined (lisinopril); excreted in breast milk (hydrochlorothiazide).
Safety and efficacy not established.
Hydrochlorothiazide is excreted by the kidneys and the risk of toxic reactions may be greater in patients with renal impairment.
Life-threatening anaphylactoid reactions have been reported with ACE inhibitors. Sensitivity reactions may occur in patients with or without a history of allergy or bronchial asthma.
Not recommended in severe renal impairment. Use with caution in mild to moderate renal impairment.
Use with caution. Minor alterations of fluid and electrolyte balance may precipitate hepatic coma.
Angioedema of the face, extremities, lips, tongue, glottis, and/or larynx has been reported in patients treated with lisinopril. This may occur at any time during treatment. Intestinal angioedema has also been reported with ACE inhibitors. Black patients have a higher incidence of angioedema compared with nonblack patients.
Aortic stenosis/hypertrophic cardiomyopathy
Use with caution in patients with obstruction in the outflow tract of the left ventricle.
Persistent nonproductive cough has been reported with all ACE inhibitors; the cough almost always resolves after discontinuation of therapy.
Dosage adjustment of insulin or oral hypoglycemic agents may be required. Hyperglycemia may occur and diabetes mellitus may manifest during administration.
Hyperkalemia, hypokalemia, hypercalcemia, hypochloremic alkalosis, hyponatremia, and hypomagnesemia may occur. Hyperkalemia is more likely to occur in patients with renal impairment or diabetes, elderly patients, or severely ill patients.
Neutropenia and bone marrow suppression may occur, and are seen more frequently in patients with renal impairment, especially if they also have collagen vascular disease.
Rarely, ACE inhibitors have been associated with a syndrome that starts with cholestatic jaundice and progresses to fulminant hepatic necrosis.
May occur or frank gout may be precipitated.
Excessive hypotension may occur, especially in severely salt- or volume-depleted patients or those with severe CHF. Syncope has been reported.
Increases in cholesterol and triglyceride levels may occur.
Hydrochlorothiazide can cause an idiosyncratic reaction, resulting in acute transient myopia and acute angle-closure glaucoma within hours to weeks of drug initiation.
In patients with severe CHF whose renal function may depend on the activity of the renin-angiotensin-aldosterone system, treatment with lisinopril may be associated with oliguria and/or progressive azotemia and, rarely, with acute renal failure and/or death. Increases in BUN and serum creatinine may occur.
The antihypertensives effects may be enhanced in the postsympathectomy patient.
Risk of hypotension may be may be increased; if hypotension occurs, it can be corrected by volume expansion.
Systemic lupus erythematosus
May exacerbate or activate systemic lupus erythematosus.
Dehydration, electrolyte imbalance (eg, hypokalemia, hypochloremia, hyponatremia), hypotension.
- Inform patients that angioedema, including laryngeal edema, may occur at any time during treatment. Advise patients to immediately report any signs or symptoms suggesting angioedema (eg, swelling of the face, extremities, eyes, lips, tongue; difficulty in swallowing or breathing) and to stop taking the medication until they have consulted with their health care provider.
- Caution patients to report light-headedness, especially during the first few days of therapy. If syncope occurs, advise patients to discontinue the medication until they have consulted their health care provider.
- Caution all patients that excessive perspiration, dehydration, vomiting, or diarrhea may lead to an excessive fall in BP because of reduction in fluid volume.
- Instruct patients not to use salt substitutes containing potassium without consulting their health care provider.
- Inform patients to promptly report any indication of infection (eg, sore throat, fever), which may be a sign of leukopenia/neutropenia.
- Inform women of childbearing age about the consequences of exposure to ACE inhibitors during pregnancy. Advise patients to report pregnancies to their health care provider as soon as possible.
- Instruct diabetic patients to monitor blood glucose more frequently when lisinopril/hydrochlorothiazide is started or their dose is changed, and to inform their health care provider of significant changes in readings.
- Caution patients to avoid sudden position changes to prevent orthostatic hypotension and to lie or sit down if they experience dizziness or light-headedness when standing.
- Instruct patients to inform their health care provider if a persistent cough develops while they are taking lisinopril/hydrochlorothiazide.
