What the FDA labels say
From the Fosinopril and hydrochlorothiazide (Fosinopril Sodium and Hydrochlorothiazide) label · effective 2024-04-28
Fosinopril sodium and hydrochlorothiazide is also contraindicated in patients who are hypersensitive to fosinopril, to any other ACE inhibitor, to hydrochlorothiazide, or other sulfonamide-derived drugs, or any other ingredient or component in the formulation.
Like other ACE inhibitors, fosinopril has been only rarely associated with hypotension in uncomplicated hypertensive patients.
The thiazide component of fosinopril sodium and hydrochlorothiazide 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.
Fosinopril sodium and hydrochlorothiazide tablets should be used cautiously in patients receiving concomitant therapy with other antihypertensives.

Neutropenia/Agranulocytosis Another angiotensin converting enzyme inhibitor, captopril, has been shown to cause agranulocytosis and bone marrow depression, rarely in uncomplicated patients but more frequently in patients with renal impairment especially if they also have a collagen vascular disease.
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.
