Benazepril and hydrochlorothiazide and Moexipril interaction
Benazepril and hydrochlorothiazide and Moexipril: 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
Lotensin HCT is also contraindicated in patients who are hypersensitive to benazepril, to any other ACE inhibitor, to hydrochlorothiazide, or to other sulfonamide-derived drugs.
Like other ACE inhibitors, benazepril has been only rarely associated with hypotension in uncomplicated hypertensive patients.
The thiazide component of Lotensin HCT may potentiate the action of other antihypertensive drugs, especially ganglionic or peripheral adrenergic-blocking drugs.
Other ACE inhibitors have had less than additive effects with beta-adrenergic blockers, presumably because drugs of both classes lower blood pressure by inhibiting parts of the renin-angiotensin system.
Lotensin HCT should be used cautiously in patients receiving concomitant therapy with other antihypertensives.
From the Moexipril (Moexipril Hydrochloride) label · effective 2026-01-23
Hypotension Moexipril hydrochloride can cause symptomatic hypotension, although, as with other ACE inhibitors, this is unusual in uncomplicated hypertensive patients treated with moexipril hydrochloride alone.
Symptomatic hypotension is most likely to occur in patients who have been salt- and volume- depleted as a result of prolonged diuretic therapy, dietary salt restriction, dialysis, diarrhea, or vomiting.
Volume- and salt-depletion should be corrected and, in general, diuretics stopped, before initiating therapy with moexipril hydrochloride (see PRECAUTIONS, Drug Interactions , and ADVERSE REACTIONS ).
In these patients, moexipril hydrochloride therapy should be started under close medical supervision, and patients should be followed closely for the first two weeks of treatment and whenever the dose of moexipril or an accompanying diuretic is increased.
Although there were no instances of severe neutropenia (absolute neutrophil count < 500/mm 3 ) among patients given moexipril hydrochloride, as with other ACE inhibitors, monitoring of white blood cell counts should be considered for patients who have collagen-vascular disease, especially if the disease is associated with impaired renal function.
