            Do not coadminister with aliskiren in patients with diabetes mellitus

            Cautions

            Acute transient myopia and acute angle-closure glaucoma has been reported, particularly with history of sulfonamide or penicillin allergy (hydrochlorothiazide is a sulfonamide)

            Not for initial treatment

            Electrolyte disturbances may occur

            Hyperkalemia, particularly when coadministered with potassium-sparing diuretics, potassium supplements, or salt substitutes; concurrent therapy with hydrochlorothiazide may reduce the frequency of this effect

            Photosensitivity may occur

            Hypotension may occur in patients who are salt or volume depleted (correct the volume depletion especially in patients receiving high dose diuretics)

            Dual blockade of the renin angiotensin system with ARBs, ACE inhibitors, or aliskiren associated with increased risk for renal function changes (including acute renal failure) compared to monotherapy

            Caution in aortic mitral stenosis, hepatic impairment, hypercholesterolemia, hypercalcemia, parathyroid disease, pre-existing renal insufficiency, systemic lupus erythematosus, bilateral renal artery stenosis or anuria

            Hydrochlorothiazide may alter glucose tolerance and raise serum levels of cholesterol and triglycerides

            Thiazides may decrease urinary calcium excretion

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.
