Uses
1 INDICATIONS AND USAGE Olmesartan medoxomil and hydrochlorothiazide is indicated for the treatment of hypertension, to lower blood pressure. Olmesartan medoxomil and hydrochlorothiazide is not indicated for the initial therapy of hypertension [see Dosage and Administration (2) ] . 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 class to which this drug principally belongs. There are no controlled trials demonstrating risk reduction with olmesartan medoxomil and hydrochlorothiazide.
Dosage
2 DOSAGE AND ADMINISTRATION The recommended starting dose of olmesartan medoxomil and hydrochlorothiazide is 40/12.5 mg once daily in patients whose blood pressure is not adequately controlled with olmesartan monotherapy. Dose can be titrated up to 40 /25 mg if necessary. The recommended starting dose of olmesartan medoxomil and hydrochlorothiazide is 20/12.5 mg once daily in patients whose blood pressure is not adequately controlled with HCT monotherapy or who experience dose-limiting adverse reactions with hydrochlorothiazide. Dose can be titrated up to 40 /25 mg if necessary. Patients titrated to the individual components (olmesartan and hydrochlorothiazide) may instead receive the corresponding dose of olmesartan medoxomil and hydrochlorothiazide.

Interactions
7 DRUG INTERACTIONS Lithium: Risk of lithium toxicity ( 7.2 ) Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Reduced diuretic, natriuretic and antihypotensive effects; increased risk of renal toxicity ( 7.3 ) Dual inhibition of the renin-angiotensin system: Increased risk of renal impairment, hypotension, and hyperkalemia ( 7.4 ) Colesevelam hydrochloride: Consider administering olmesartan at least 4 hours before colesevelam hydrochloride dose ( 7.5 ) Antidiabetic drugs: Dosage adjustment may be required ( 7.6 ) Cholestyramine and colestipol: Reduced absorption of thiazides ( 7.6 ) 7.1 Agents Increasing Serum Potassium Coadministration of olmesartan medoxomil and hydrochlorothiazide with other drugs that raise serum potassium levels may result in hyperkalemia.
Warnings
WARNING: FETAL TOXICITY When pregnancy is detected, discontinue olmesartan medoxomil and hydrochlorothiazide as soon as possible [see Warnings and Precautions (5.1) ] . Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus [see Warnings and Precautions (5.1) ] . WARNING: FETAL TOXICITY See full prescribing information for complete boxed warning. 5 WARNINGS AND PRECAUTIONS Hypotension: Correct volume-depletion prior to administration. ( 5.2 ) Monitor renal function and potassium in susceptible patients ( 5.3 ) Observe for signs of fluid or electrolyte imbalance. ( 5.4 ) Acute angle-closure glaucoma ( 5.5 ) Sprue-like enteropathy has been reported. Consider discontinuation of olmesartan medoxomil and hydrochlorothiazide in cases where no other etiology is found ( 5.7 ) 5.1 Fetal Toxicity Pregnancy Category D 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. 4 CONTRAINDICATIONS Olmesartan medoxomil and hydrochlorothiazide is contraindicated: In patients with hypersensitivity to any component of olmesartan medoxomil and hydrochlorothiazide [see Adverse Reactions ( 6.1 , 6.2 )] In patients with anuria [see Warnings and Precautions (5.3) and Adverse Reactions (6.1) ] For coadministration with aliskiren in patients with diabetes [ s ee Drug Interactions (...
Pregnancy
8.1 Pregnancy Pregnancy Category D 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 olmesartan medoxomil and hydrochlorothiazide as soon as possible.
