Monopril HCT® (fosinopril / hydrochlorothiazide)

With an elimination pathway that adapts as kidney function changes, Monopril HCT is designed for people who need more than one blood pressure medication. After you book, your clinician reviews your history so your visit is about finding the right fit for you, whether that's Monopril HCT or another option.

Two blood pressure medications in one pill — reduces daily tablet count

Fosinopril uses dual liver and kidney elimination — useful when kidney function declines

Available as a low-cost generic (fosinopril/hydrochlorothiazide)

What is Monopril HCT (Fosinopril - hydrochlorothiazide)?

Monopril HCT is a combination blood pressure medication pairing fosinopril, an ACE inhibitor, with hydrochlorothiazide (HCTZ), a thiazide diuretic. Fosinopril reduces blood pressure by blocking the enzyme that produces angiotensin II—a potent vasoconstrictor—while HCTZ lowers blood pressure by increasing renal excretion of salt and water to reduce blood volume. The two mechanisms work synergistically, and their combination produces greater blood pressure reduction than either alone. Fosinopril is notably excreted through both the kidneys and liver, making it a useful option for patients with mild-to-moderate kidney impairment. It's taken once daily.

ACE inhibition and diuresis combination

Fosinopril blocks angiotensin-converting enzyme, preventing angiotensin II production and causing vasodilation, while HCTZ reduces circulating fluid volume through renal sodium excretion—two complementary and additive blood pressure-lowering mechanisms in a single tablet.

Dual elimination pathway advantage

Fosinopril is unique among ACE inhibitors in being eliminated through both renal and hepatic routes, making dose adjustment less critical as kidney function declines—a practical advantage for hypertensive patients with comorbid kidney disease.

Electrolyte balance considerations

ACE inhibitors tend to retain potassium while thiazide diuretics waste it—the combination partially offsets this risk, though electrolyte monitoring remains important, particularly in patients with kidney disease or on other medications affecting potassium.

Frequently asked questions

Why are two blood pressure medications combined in Monopril HCT?

Combining fosinopril (an ACE inhibitor) and hydrochlorothiazide (a diuretic) in one tablet targets blood pressure through two complementary mechanisms — greater reduction than either alone — while simplifying the daily regimen to a single pill.

What makes fosinopril different from other ACE inhibitors?

Fosinopril is eliminated through both the liver and kidneys — unlike most ACE inhibitors that rely primarily on renal excretion. This dual elimination pathway makes it more flexible for patients with mild-to-moderate kidney disease.

How long before Monopril HCT lowers my blood pressure?

Blood pressure reduction typically begins within the first week. Full effect at a given dose develops over 2–4 weeks. Your clinician may adjust the dose after an adequate trial period if blood pressure targets aren't met.

What side effects might I experience?

Dry cough from fosinopril, dizziness upon standing, increased urination, low potassium, and elevated uric acid from HCTZ are the most commonly reported effects. The cough is the most frequent reason patients switch from ACE inhibitors to ARBs.

Can I take Monopril HCT during pregnancy?

No. Fosinopril — like all ACE inhibitors — is contraindicated in pregnancy and can cause serious fetal harm. Stop taking it immediately and contact your clinician if pregnancy occurs.
