What the FDA labels say

From the Fosinopril and hydrochlorothiazide (Fosinopril Sodium and Hydrochlorothiazide) label · effective 2024-04-28

Major

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.

Contraindicationsby drug classView label on DailyMed
Moderate

Like other ACE inhibitors, fosinopril has been only rarely associated with hypotension in uncomplicated hypertensive patients.

Warningsby drug classView label on DailyMed
Moderate

The thiazide component of fosinopril sodium and hydrochlorothiazide may potentiate the action of other antihypertensive drugs, especially ganglionic or peripheral adrenergic-blocking drugs.

Warningsby drug classView label on DailyMed
Moderate

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.

Drug interactionsby drug classView label on DailyMed
Minor

Fosinopril sodium and hydrochlorothiazide tablets should be used cautiously in patients receiving concomitant therapy with other antihypertensives.

Warningsby drug classView label on DailyMed

From the Trandolapril label · effective 2024-05-30

Moderate

Like other ACE inhibitors, trandolapril has only rarely been associated with symptomatic hypotension in uncomplicated hypertensive patients.

Warningsby drug classView label on DailyMed
Moderate

Symptomatic hypotension is most likely to occur in patients who have been salt- or volume-depleted as a result of prolonged treatment with diuretics, dietary salt restriction, dialysis, diarrhea, or vomiting.

Warningsby drug classView label on DailyMed
Moderate

These patients should be followed closely during the first 2 weeks of treatment and, thereafter, whenever the dosage of trandolapril or diuretic is increased.

Warningsby drug classView label on DailyMed
Moderate

A transient hypotensive response is not a contraindication to further doses; however, lower doses of trandolapril or reduced concomitant diuretic therapy should be considered.

Warningsby drug classView label on DailyMed
Moderate

As with other ACE inhibitors, periodic monitoring of white blood cell counts in patients with collagen-vascular disease and/or renal disease should be considered.
