What Benazepril Is and How It Works
Benazepril is an angiotensin‑converting enzyme (ACE) inhibitor used to treat high blood pressure (hypertension) and to help protect the kidneys in certain patients with proteinuric chronic kidney disease. It is taken by mouth as benazepril hydrochloride tablets. This blood pressure medication may be used alone or with other agents such as thiazide diuretics. Benazepril lowers blood pressure by blocking the conversion of angiotensin I to angiotensin II, which relaxes blood vessels and reduces aldosterone‑mediated sodium and water retention.

Benazepril is usually taken once daily, with or without food. Commonly used strengths include benazepril 5 mg, benazepril 10 mg, benazepril 20 mg, and 40 mg tablets. Treatment is individualized and titrated based on blood pressure response and tolerability.
Dosage and Usage
- Initiation: Typical adult starting dose is 10 mg once daily if not on a diuretic. Lower starting doses (5 mg) are often used when taking a diuretic or in certain renal impairment.
- Titration: Dose may increase every 1–2 weeks based on response. Usual maintenance is 20–40 mg daily, given once daily or in two divided doses.
- Maximum dosage: Do not exceed a total of 80 mg benazepril per day.
- Administration: Swallow benazepril tablets with water. Tablets may be split if scored and directed by a prescriber.
- Consistency: Take at the same time each day.
- With other agents: Combination therapy (e.g., benazepril and hydrochlorothiazide) may be used when additional control is needed.
- Missed dose: Take as soon as remembered unless it is close to the next dose. Skip the missed dose if near the next scheduled time. Do not double doses.
- Monitoring: Blood pressure and kidney function are typically checked during titration and periodically thereafter.
- Potassium: Benazepril can increase potassium. Potassium supplements or salt substitutes containing potassium may raise levels.
- Alcohol and dehydration: Excess alcohol, dehydration, or heavy sweating can increase the risk of low blood pressure.
- Storage: Keep tablets at 20–25°C (68–77°F). Short excursions 15–30°C (59–86°F) are acceptable.
- Moisture: Store in the original, tightly closed container. Protect from moisture and humidity.
- Light and heat: Keep away from direct heat and sunlight. Do not store in a bathroom.
- Travel: Carry in hand luggage with the labeled pharmacy bottle.
- Travel timing: Bring enough for the full trip plus extra days.
- Do not freeze: Tablets should not be frozen.
Benefits and Savings
Benazepril lowers blood pressure and reduces cardiovascular risk when used as directed. It helps relax blood vessels, which eases the workload on the heart. In patients with proteinuric kidney disease, ACE inhibitors can reduce albuminuria and slow kidney function decline. Once‑daily dosing is convenient for many adults.
Benazepril is a long‑established generic with broad availability across strengths. Many customers save 60–80% vs typical U.S. prices. Partner pharmacies are licensed and vetted, dispense authentic medications, and offer a broad selection with value‑focused pricing.
People with diabetic or hypertensive kidney disease may be managed with ACE inhibitors as part of a comprehensive plan alongside lifestyle changes and other medicines.
Side Effects and Safety
- Common effects: dry cough, dizziness, headache, fatigue.
- Gastrointestinal: nausea, diarrhea.
- Laboratory: increased potassium (hyperkalemia), small rises in creatinine during initiation.
- Skin: rash or pruritus.
- Orthostatic symptoms: lightheadedness when standing up quickly.
Serious but less common risks include angioedema (swelling of face, lips, tongue, or throat), severe hypotension, marked hyperkalemia, and kidney function changes. ACE inhibitors carry a boxed warning for fetal toxicity; discontinue if pregnancy occurs. Avoid use with aliskiren in diabetes. Rare hepatic injury has been reported. Use caution with bilateral renal artery stenosis, volume depletion, or when combined with NSAIDs, which may blunt antihypertensive effect and impact kidney function.
Onset Time
Initial blood pressure reductions can appear within the first week. The full antihypertensive effect generally develops over 2–4 weeks as dosing is titrated and steady state is reached. For kidney protection in proteinuric disease, reductions in albuminuria may be seen within weeks, while stabilization of kidney function is evaluated over months of consistent treatment.
Compare With Alternatives
Benazepril is one option within ACE inhibitors. Other ACE inhibitors include lisinopril and ramipril, which have similar mechanisms and outcomes. Some patients who develop ACE‑inhibitor cough may be switched to an angiotensin receptor blocker (ARB), which blocks the angiotensin II receptor rather than inhibiting its formation.
Fixed‑dose combinations pair a renin‑angiotensin agent with a diuretic. If edema or additional diuresis is needed, a thiazide like Hydrochlorothiazide may be considered in combination products. For those needing an ARB plus thiazide, options such as Irbesartan Htc are commonly used. Selection depends on blood pressure targets, tolerability, kidney function, and coexisting conditions.
Combination Therapy
- ACE inhibitor + thiazide diuretic: Benazepril with hydrochlorothiazide can improve blood pressure control.
- ACE inhibitor + calcium channel blocker: Amlodipine pairs well with benazepril for additional vasodilation.
- ACE inhibitor + beta blocker: Used when heart rate control or post‑MI therapy is also needed.
- Diuretics: Starting benazepril while on a diuretic often uses a lower initial dose to limit hypotension.
- Potassium‑sparing diuretics: Agents like spironolactone can increase potassium; combined use typically involves close monitoring.
- Avoid aliskiren in diabetes: Concomitant use is generally contraindicated due to safety concerns.
Patient Suitability and Cost‑Saving Tips
Adults with essential hypertension are common candidates for benazepril. It is also used in proteinuric chronic kidney disease to reduce albuminuria and in certain heart failure regimens when appropriate. Those with a history of angioedema related to ACE inhibitor therapy should not receive benazepril. Use is contraindicated in pregnancy, and generally avoided during breastfeeding or requires careful clinical judgment.
People with significant hyperkalemia, severe bilateral renal artery stenosis, or acute kidney injury may not be good candidates. Drug interactions include lithium (may increase lithium levels) and NSAIDs, which can reduce antihypertensive effect and impact kidney function. Alcohol excess and dehydration can increase the risk of dizziness or low blood pressure.
Cost‑saving ideas include choosing generic benazepril tablets, consolidating to once‑daily dosing when clinically appropriate, and using multi‑month quantities to reduce per‑fill fees. Reorder reminders help prevent gaps in therapy. CanadianInsulin provides prompt, express, cold‑chain shipping to the U.S. for a smooth delivery experience.

What is Benazepril used for?
Benazepril is an ACE inhibitor used to treat high blood pressure. It relaxes blood vessels and reduces aldosterone effects, lowering blood pressure and cardiovascular risk. It is also used to reduce proteinuria and help protect kidney function in certain chronic kidney disease settings when clinically appropriate.
What strengths and dosages of Benazepril are available?
Benazepril tablets commonly come as 5 mg, 10 mg, 20 mg, and 40 mg. Typical adult initiation is 10 mg once daily if not on a diuretic, with titration to 20–40 mg daily. The benazepril maximum dosage is 80 mg per day, given once daily or in two divided doses, based on response.
How long does Benazepril take to lower blood pressure?
Initial effects are often seen within the first week, with the full blood pressure response usually established over 2–4 weeks as the dose is adjusted. Kidney‑related benefits, such as reduced albuminuria, can appear within weeks, while long‑term kidney protection is assessed over months.
What are common Benazepril side effects and serious risks?
Common effects include dry cough, dizziness, headache, fatigue, and mild digestive symptoms. Serious risks include angioedema (facial or throat swelling), severe hypotension, high potassium, and kidney function changes. ACE inhibitors carry a boxed warning for fetal toxicity and should be stopped if pregnancy occurs.
Who should not take Benazepril?
It should not be used in pregnancy or in anyone with a history of ACE‑inhibitor–related angioedema. Caution or alternative therapy may be needed with bilateral renal artery stenosis, significant hyperkalemia, or acute kidney issues, and when using aliskiren in diabetes or NSAIDs that can affect kidney function.
Can Benazepril be taken with potassium or salt substitutes?
Benazepril can increase potassium levels. Potassium supplements and salt substitutes containing potassium may raise the risk of hyperkalemia, especially with kidney impairment or potassium‑sparing diuretics. Clinicians often monitor potassium and kidney function and may limit additional potassium sources during therapy.
