Amlodipine and valsartan and Benazepril and hydrochlorothiazide: both prescribing labels flag this combination with the strongest language, such as a contraindication, a boxed warning, or an instruction to avoid it.
Do not combine without a prescriber's guidance. The label language below is the strongest FDA uses.
What the FDA labels say
From the Benazepril and hydrochlorothiazide (Lotensin HCT) label · effective 2026-02-24
Do not administer Lotensin HCT within 36 hours of switching to or from sacubitril/valsartan, a neprilysin inhibitor (see WARNINGS and PRECAUTIONS ).
Do not coadminister aliskiren with angiotensin receptor blockers, ACE inhibitors, including Lotensin HCT in patients with diabetes.
The thiazide component of Lotensin HCT may potentiate the action of other antihypertensive drugs, especially ganglionic or peripheral adrenergic-blocking drugs.
Dual Blockade of the Renin-Angiotensin System (RAS): Dual Blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypertension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy.
Lotensin HCT should be used cautiously in patients receiving concomitant therapy with other antihypertensives.
From the Amlodipine and valsartan label · effective 2026-04-16
In patients with an activated renin-angiotensin system, such as volume- and/or salt-depleted patients receiving high doses of diuretics, symptomatic hypotension may occur in patients receiving angiotensin receptor blockers.
Valsartan Agents Increasing Serum Potassium: Concomitant use of valsartan with other agents that block the renin-angiotensin system, potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride), potassium supplements, salt substitutes containing potassium or other drugs that may increase potassium levels (e.g., heparin) may lead to increases in…
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, coadministration of NSAIDs, including selective COX-2 inhibitors, with angiotensin II receptor antagonists, including valsartan, may…
Dual Blockade of the Renin-Angiotensin System (RAS) : Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy.
Impaired Renal Function Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system and by diuretics.
