Irbesartan And Hydrochlorothiazide

1 INDICATIONS AND USAGE Irbesartan and hydrochlorothiazide tablets are indicated for the treatment of hypertension. Irbesartan and hydrochlorothiazide tablets may be used in patients whose blood pressure is not adequately controlled on monotherapy. Irbesartan and hydrochlorothiazide tablets may also be used as initial therapy in patients who are likely to need multiple drugs to achieve their blood pressure goals. The choice of irbesartan and hydrochlorothiazide tablets as initial therapy for hypertension should be based on an assessment of potential benefits and risks.

6 ADVERSE REACTIONS Most common adverse events (≥5% on irbesartan and hydrochlorothiazide tablets and more often than on placebo) are dizziness, fatigue, and musculoskeletal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Teva at 1-888-838-2872 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.

8.1 Pregnancy Risk Summary Irbesartan and hydrochlorothiazide 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.

WARNING: FETAL TOXICITY When pregnancy is detected, discontinue irbesartan and hydrochlorothiazide tablets as soon as possible [see Warnings and Precautions ( 5.1 ) and Use in Specific Populations ( 8.1 )]. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus [see Warnings and Precautions ( 5.1 ) and Use in Specific Populations ( 8.1 )] . WARNING: FETAL TOXICITY See full prescribing information for complete boxed warning . 5 WARNINGS AND PRECAUTIONS Hypotension: Correct volume depletion prior to administration. ( 5.2 ) Impaired renal function. ( 5.7 ) Thiazide diuretics may cause an exacerbation or activation of systemic lupus erythematosus. ( 5.4 ) Acute angle-closure glaucoma, acute myopia, and choroidal effusion. ( 5.8 ) 5.1 Fetal Toxicity Irbesartan and hydrochlorothiazide 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. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. 4 CONTRAINDICATIONS Irbesartan and hydrochlorothiazide tablets are contraindicated in patients who are hypersensitive to any component of this product. Because of the hydrochlorothiazide component, this product is contraindicated in patients with anuria or hypersensitivity to other sulfonamide-derived drugs.
