🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Telmisartan and hydrochlorothiazide tablets are indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal 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 classes to which this drug principally belongs.
There are no controlled trials demonstrating risk reduction with telmisartan and hydrochlorothiazide tablets. 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 [see Clinical Studies (14)]. Telmisartan and hydrochlorothiazide tablets are not indicated for initial therapy for the treatment of hypertension [see Dosage and Administration (2.1)].
Telmisartan and hydrochlorothiazide tablets may be used alone or in combination with other antihypertensive agents. • Telmisartan and hydrochlorothiazide tablets are a combination of an angiotensin II receptor blocker (ARB) and a thiazide diuretic indicated for the treatment of hypertension, alone or with other antihypertensive agents, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions (1) • Telmisartan and hydrochlorothiazide tablets are not indicated for initial therapy (1).
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION • Usual starting dose is 80 mg/12.5 mg once daily (2.1) • Titrate up to 160 mg/25 mg as needed (2.1) • Initiate patients with biliary obstructive disorders or hepatic insufficiency at 40 mg/12.5 mg (2.2)
2.1Dosing Information Initiate a patient whose blood pressure is not adequately controlled with telmisartan monotherapy 80 mg on telmisartan and hydrochlorothiazide tablet 80 mg/12.5 mg orally once daily. Dose can be titrated up to 160 mg/25 mg after 2 to 4 weeks, if necessary. Initiate a patient whose blood pressure is not adequately controlled by 25 mg once daily of hydrochlorothiazide, or is controlled but who experiences hypokalemia with this regimen on telmisartan and hydrochlorothiazide tablet 80 mg/12.5 mg once daily.
Dose can be titrated up to 160 mg/25 mg after 2 to 4 weeks, if necessary. Patients titrated to the individual components (telmisartan and hydrochlorothiazide) may instead receive the corresponding dose of telmisartan and hydrochlorothiazide tablets. Telmisartan and hydrochlorothiazide tablets may be administered with other antihypertensive drugs.
2.2Dose Adjustment for Hepatic Impairment Initiate patients with biliary obstructive disorders or hepatic insufficiency under close medical supervision using the 40 mg/12.5 mg combination. Telmisartan and hydrochlorothiazide tablets are not recommended for patients with severe hepatic impairment [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].
2.3Important Administration Instructions Telmisartan and hydrochlorothiazide tablets should not be removed from blisters or bottles until immediately before administration.

4 CONTRAINDICATIONS Telmisartan and hydrochlorothiazide tablets are contraindicated: · In patients who are hypersensitive to any component of this product [see Warnings and Precautions (5.5)]. · In patients with anuria. · For co-administration with aliskiren in patients with diabetes [see Drug Interactions (7.4)]. • Hypersensitivity to telmisartan or any component (4) • Anuria (4) • Co-Administration with aliskiren in patients with diabetes (4)
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Avoid fetal or neonatal exposure (5.1) · Correct volume or salt depletion before initiating therapy. Observe for signs and symptoms of hypotension (5.2) · Monitor renal function and potassium in susceptible patients (5.3) · Observe for clinical signs of fluid or electrolyte imbalance (5.4) · Hypersensitivity Reaction (5.5) · Acute Myopia and Secondary Angle-Closure Glaucoma (5.6)
5.1Fetal Toxicity Telmisartan Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death.
When pregnancy is detected, discontinue telmisartan and hydrochlorothiazide tablets as soon as possible. Hydrochlorothiazide Thiazides cross the placental barrier and appear in cord blood. Adverse reactions include fetal or neonatal jaundice and thrombocytopenia [see Use in Specific Populations (8.1)].
5.2Hypotension in Volume-or Salt-Depleted Patients In patients with an activated renin-angiotensin system, such as volume-or salt-depleted patients (e.g., those being treated with high doses of diuretics), symptomatic hypotension may occur after initialization of treatment with telmisartan and hydrochlorothiazide tablets. Correct volume or salt depletion prior to administration of telmisartan and hydrochlorothiazide tablets.
5.3Impaired Renal Function Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system and by diuretics. Patients whose renal function may depend in part on the activity of the renin-angiotensin system (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion) may be at particular risk of developing oliguria, progressive azotemia, or acute renal failure on telmisartan and hydrochlorothiazide tablets.
Monitor renal function periodically in these patients. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function on telmisartan and hydrochlorothiazide tablets.
5.4Electrolytes and Metabolic Disorders Drugs, including telmisartan, that inhibit the renin-angiotensin system can cause hyperkalemia, particularly in patients with renal insufficiency, diabetes, or combination use with other angiotensin receptor blockers or ACE inhibitors and the concomitant use of other drugs that raise serum potassium levels [see Drug Interactions (7.1, 7.4)] . Hydrochlorothiazide can cause hypokalemia and hyponatremia. Thiazides have been shown to increase the urinary excretion of magnesium; this may result in hypomagnesemia.
Hypomagnesemia can result in hypokalemia which may be difficult to treat despite potassium repletion. Monitor serum electrolytes periodically. In controlled trials using the telmisartan/hydrochlorothiazide combination treatment, no patient administered 40 mg/12.5 mg, 80 mg/12.5 mg, or 80 mg/25 mg experienced a decrease in potassium ≥1.4 mEq/L, and no patient experienced hyperkalemia.
Hydrochlorothiazide decreases urinary calcium excretion and may cause elevations of serum calcium. Hydrochlorothiazide may alter glucose tolerance and raise serum levels of cholesterol and triglycerides. Hyperuricemia may occur or frank gout may be precipitated in certain patients receiving thiazide therapy.
Because telmisartan decreases uric acid, telmisartan in combination with hydrochlorothiazide attenuates the diuretic-induced hyperuricemia.
5.5Hypersensitivity Reaction Hydrochlorothiazide Hypersensitivity reactions to hydrochlorothiazide may occur in patients with or without a history of allergy or bronchial asthma, but are more likely in patients with such a history [see Contraindications (4)].

6 ADVERSE REACTIONS The following adverse reactions are discussed elsewhere in labeling: · Hypotension [see Warnings and Precautions (5.2)] · Renal Impairment [see Warnings and Precautions (5.3)] · Electrolytes and Metabolic Disorders [see Warnings and Precautions (5.4)] The most common adverse reactions (≥2% of patients) were upper respiratory tract infection, dizziness, sinusitis, diarrhea, fatigue, influenza-like symptoms, and nausea (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Alembic Pharmaceuticals Limited at 1-866-210-9797 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Telmisartan and hydrochlorothiazide tablet has been evaluated for safety in more than 1700 patients, including 716 treated for hypertension for longer than 6 months and 420 for more than 1 year. Adverse reactions have been limited to those that have been previously reported with telmisartan and/or hydrochlorothiazide.
Adverse reactions occurring at an incidence of ≥2% in patients treated with telmisartan/hydrochlorothiazide and at a greater rate than in patients treated with placebo, are presented in Table 1 [see Clinical Studies (14)]. Table 1: Adverse Reactions Occurring at an Incidence of ≥2% in Patients Treated with Telmisartan/Hydrochlorothiazide and at a Greater Rate Than in Patients Treated with Placebo* Telmisartan/ Hydrochlorothiazide (N=414) Placebo (N=74) Telmisartan (N=209) Hydrochlorothiazide (N=121) Body as a whole Fatigue 3% 1% 3% 3% Influenza-like symptoms 2% 1% 2% 3% Central/peripheral nervous system Dizziness 5% 1% 4% 6% Gastrointestinal system Diarrhea 3% 0% 5% 2% Nausea 2% 0% 1% 2% Respiratory system disorder Sinusitis 4% 3% 3% 6% Upper respiratory tract infection 8% 7% 7% 10% * includes all doses of telmisartan (20 to 160 mg), hydrochlorothiazide (6.25 to 25 mg), and combinations thereof Other adverse reactions observed for telmisartan/hydrochlorothiazide were: pain (including back and abdominal), dyspepsia, erythema, vomiting, bronchitis, and pharyngitis.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Lithium: Risk of lithium toxicity (7.2) • Non-steroidal anti-inflammatory drugs (NSAIDs): Reduced diuretic, natriuretic, and antihypertensive effects; increased risk of renal impairment (7.3) • Dual blockade of renin-angiotensin system: Increased risk of renal impairment, hypotension, and hyperkalemia (7.4) • Antidiabetic drugs: Dosage adjustment may be required (7.6) • Cholestyramine and colestipol: Reduced absorption of thiazides (7.7)
7.1Agents Increasing Serum Potassium Co-administration of telmisartan with other drugs that raise serum potassium levels may result in hyperkalemia. Monitor serum potassium in such patients.
7.2Lithium Increases in serum lithium concentrations and lithium toxicity have been reported with concomitant use of thiazide diuretics or angiotensin II receptor antagonists, including telmisartan. Monitor lithium levels in patients receiving telmisartan and hydrochlorothiazide tablets and lithium.
7.3Non-Steroidal Anti-Inflammatory Agents including Selective Cyclooxygenase-2 Inhibitors Telmisartan Non-Steroidal Anti-Inflammatory Agents including Selective Cyclooxygenase-2 Inhibitors (COX-2 Inhibitors): In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, co-administration of NSAIDs, including selective COX-2 inhibitors, with ARBs, including telmisartan, may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible.
The antihypertensive effect of ARBs may be attenuated by NSAIDs. Therefore, monitor renal function and blood pressure periodically in patients receiving telmisartan and hydrochlorothiazide tablets and NSAIDs. Hydrochlorothiazide Administration of a non-steroidal anti-inflammatory agent, including a selective COX-2 inhibitor, can reduce the diuretic, natriuretic, and antihypertensive effects of diuretics.
Therefore, when telmisartan and hydrochlorothiazide tablets and non-steroidal anti-inflammatory agents including selective COX-2 inhibitors are used concomitantly, observe closely to determine if the desired effect of the diuretic is obtained.
7.4Dual Blockade of the Renin-Angiotensin-Aldosterone System and Changes in Renal Function Dual blockade of the renin-angiotensin-aldosterone system (RAS) with angiotensin blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and renal impairment. The ONTARGET trial enrolled 25,620 patients ≥55 years old with atherosclerotic disease or diabetes with end-organ damage, randomizing them to telmisartan (ARB) only, ramipril (ACE inhibitor) only, or the combination, and followed them for a median of 56 months.
Patients who received the combination of ARB and ACE inhibitor did not obtain any additional benefit (no additional reduction of risk of cardiovascular death, myocardial infarction, stroke, or hospitalization from heart failure) compared to ARB monotherapy or ACE inhibitor monotherapy, but experienced an increased incidence of renal dysfunction (e.g., acute renal failure) compared with monotherapy groups. In general, avoid combined use of RAS inhibitors. Closely monitor blood pressure, renal function and electrolytes in patients on telmisartan and hydrochlorothiazide tablets and other agents that affect the RAS.
Do not co-administer aliskiren with telmisartan and hydrochlorothiazide tablets in patients with diabetes. Avoid concomitant use of aliskiren with telmisartan and hydrochlorothiazide tablets in patients with renal impairment (GFR <60 mL/min/1.73 m 2 ).
7.5Digoxin When telmisartan was co-administered with digoxin, median increases in digoxin peak plasma concentration (49%) and in trough concentration (20%) were observed. Monitor digoxin levels in patients taking concomitant telmisartan and hydrochlorothiazide tablets and digoxin.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS • Lactation: Do not breastfeed during treatment with telmisartan and hydrochlorothiazide tablets (8.2) • Severe Hepatic Impairment: Use not recommended (8.6) • Severe Renal Impairment: Use not recommended (8.7)
8.1Pregnancy Risk Summary Telmisartan and hydrochlorothiazide tablets can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death (see Clinical Considerations). Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents.
Studies in rats and rabbits with telmisartan showed fetotoxicity only at maternally toxic doses ( see Data ). When pregnancy is detected, discontinue telmisartan and hydrochlorothiazide tablets as soon as possible. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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. Pregnant women with hypertension should be carefully monitored and managed accordingly. Fetal/Neonatal adverse reactions Telmisartan Use of drugs that act on the RAS in the second and third trimesters of pregnancy can result in the following: oligohydramnios, reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations, including skull hypoplasia, hypotension, and death.
In the unusual case that there is no appropriate alternative to therapy with drugs affecting the renin-angiotensin system for a particular patient, apprise the mother of the potential risk to the fetus. In patients taking telmisartan and hydrochlorothiazide tablets during pregnancy, perform serial ultrasound examinations to assess the intra-amniotic environment. Fetal testing may be appropriate, based on the week of gestation.
If oligohydramnios is observed, discontinue telmisartan and hydrochlorothiazide tablets, unless it is considered lifesaving for the mother. Patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. Closely observe infants with histories of in utero exposure to telmisartan and hydrochlorothiazide tablets for hypotension, oliguria, and hyperkalemia.
If oliguria or hypotension occurs, support blood pressure and renal perfusion. Exchange transfusions or dialysis may be required as a means of reversing hypotension and replacing renal function [see Use in Specific Populations (8.4)]. Hydrochlorothiazide Thiazides cross the placenta, and use of thiazides during pregnancy is associated with a risk of fetal or neonatal jaundice, thrombocytopenia, and possible other adverse reactions that have occurred in adults.
Data Animal Data Telmisartan and Hydrochlorothiazide Tablets A developmental toxicity study was performed in rats with telmisartan/hydrochlorothiazide doses of 3.2/1, 15/4.7, 50/15.6, and 0/15.6 mg/kg/day. Although the two higher dose combinations appeared to be more toxic (significant decrease in body weight gain) to the dams than either drug alone, there did not appear to be an increase in toxicity to the developing embryos.

Neonates with a history of in utero exposure to telmisartan and hydrochlorothiazide tablets : If oliguria or hypotension occurs, support blood pressure and renal perfusion. Exchange transfusions or dialysis may be required as means of reversing hypotension and/or substituting for disordered renal function.
🧓 Geriatric Use ▾
8.5Geriatric Use In the controlled clinical trials (n=1017), approximately 20% of patients treated with telmisartan/hydrochlorothiazide were 65 years of age or older, and 5% were 75 years of age or older. No overall differences in effectiveness and safety of telmisartan/hydrochlorothiazide were observed in these patients compared to younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function and of concomitant diseases or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE Telmisartan Limited data are available with regard to overdosage of telmisartan in humans. The most likely manifestations of overdosage with telmisartan are hypotension, dizziness, and tachycardia; bradycardia could occur from parasympathetic (vagal) stimulation. If symptomatic hypotension should occur, supportive treatment should be instituted.
Telmisartan is not removed by hemofiltration and is not dialyzable. Hydrochlorothiazide The most common signs and symptoms observed in patients with a hydrochlorothiazide overdose are those caused by electrolyte depletion (hypokalemia, hypochloremia, hyponatremia) and dehydration resulting from excessive diuresis. If digitalis has also been administered, hypokalemia may accentuate cardiac arrhythmias.
The degree to which hydrochlorothiazide is removed by hemodialysis has not been established. The oral LD 50 of hydrochlorothiazide is greater than 10 g/kg in both mice and rats.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Telmisartan and Hydrochlorothiazide Tablets Telmisartan and hydrochlorothiazide tablets are a combination of two drugs with antihypertensive properties: a thiazide diuretic, hydrochlorothiazide, and an angiotensin II receptor blocker (ARB), telmisartan. Telmisartan Angiotensin II is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme (ACE, kininase II). Angiotensin II is the principal pressor agent of the renin-angiotensin system, with effects that include vasoconstriction, stimulation of synthesis and release of aldosterone, cardiac stimulation, and renal reabsorption of sodium.
Telmisartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT 1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland. Its action is therefore independent of the pathways for angiotensin II synthesis. There is also an AT 2 receptor found in many tissues, but AT 2 is not known to be associated with cardiovascular homeostasis.
Telmisartan has much greater affinity (>3,000-fold) for the AT1 receptor than for the AT 2 receptor. Telmisartan does not inhibit ACE (kininase II) nor does it bind to or block other hormone receptors or ion channels known to be important in cardiovascular regulation. Blockade of the angiotensin II receptor inhibits the negative regulatory feedback of angiotensin II on renin secretion, but the resulting increased plasma renin activity and angiotensin II circulating levels do not overcome the effect of telmisartan on blood pressure.
Hydrochlorothiazide Hydrochlorothiazide is a thiazide diuretic. Thiazides affect the renal tubular mechanisms of electrolyte reabsorption, directly increasing excretion of sodium salt 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 renin-aldosterone link is mediated by angiotensin II, so co-administration of an ARB tends to reverse the potassium loss associated with these diuretics. The mechanism of the antihypertensive effect of thiazides is not fully understood.
12.2Pharmacodynamics Telmisartan In normal volunteers, a dose of telmisartan 80 mg inhibited the pressor response to an intravenous infusion of angiotensin II by approximately 90% at peak plasma concentrations with approximately 40% inhibition persisting for 24 hours. Plasma concentration of angiotensin II and plasma renin activity increased in a dose-dependent manner after single administration of telmisartan to healthy subjects and repeated administration to hypertensive patients. The once-daily administration of up to 80 mg telmisartan to healthy subjects did not influence plasma aldosterone concentrations.
In multiple dose studies with hypertensive patients, there were no clinically significant changes in electrolytes (serum potassium or sodium) or in metabolic function (including serum levels of cholesterol, triglycerides, HDL, LDL, glucose, or uric acid). The antihypertensive effects of telmisartan have been studied in six placebo-controlled clinical trials including a total of 1773 patients with mild to moderate hypertension (diastolic blood pressure of 95 to 114 mmHg), 1031 of whom were treated with telmisartan. Following once-daily administration of telmisartan, the magnitude of blood pressure reduction from baseline after placebo subtraction was approximately (SBP/DBP) 6 to 8/6 mmHg for 20 mg, 9 to 13/6 to 8 mmHg for 40 mg, and 12 to 13/7 to 8 mmHg for 80 mg.
Larger doses (up to 160 mg) did not appear to cause a further decrease in blood pressure. The onset of antihypertensive activity occurs within 3 hours, with a maximal reduction by approximately 4 weeks. At doses of 20, 40, and 80 mg, the antihy…
