Version July 2025
When pregnancy is detected, discontinue perindopril/amlodipine as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.
Hypertension: Oral: Initial: Perindopril 3.5 mg/amlodipine 2.5 mg once daily; adjust dose to response in 7- to 14-day intervals; maximum dose: perindopril 14 mg/amlodipine 10 mg per day.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
CrCl 30 to 80 mL/minute: Maximum dose: Perindopril 7 mg/amlodipine 5 mg per day.
CrCl <30 mL/minute: Use is not recommended.
Hemodialysis: Perindopril and perindoprilat are dialyzable. Amlodipine is not dialyzable.
There are dosage adjustments provided in the manufacturer’s labeling. Perindoprilat bioavailability is increased and amlodipine clearance is decreased with hepatic impairment.
Refer to adult dosing.
The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified. Frequency not always defined.
1% to 10%:
Cardiovascular: Peripheral edema (2% to 7%), exacerbation of angina pectoris, hypotension, myocardial infarction (more likely in patients with severe obstructive coronary artery disease)
Central nervous system: Dizziness (3%), headache (3%)
Dermatologic: Skin rash
Endocrine & metabolic: Hyperkalemia (2%)
Gastrointestinal: Diarrhea, nausea
Renal: Renal insufficiency
Respiratory: Cough (3%)
Hypersensitivity to perindopril, other ACE inhibitors, amlodipine, or any component of the formulation; hereditary or idiopathic angioedema, with or without previous ACE inhibitor treatment; concomitant use with aliskiren in patients with diabetes; concomitant use or within 36 hours of switching to or from a neprilysin inhibitor (eg, sacubitril).
Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to other dihydropyridine derivatives; renal impairment (CrCl <60 mL/minute); pregnant women, women planning to become pregnant, or women of childbearing potential not using adequate contraceptive; breastfeeding; mitral valve stenosis and left ventricular outflow tract obstruction (eg, aortic stenosis, hypertrophic cardiomyopathy); heart failure; bilateral renal artery stenosis or renal artery stenosis in a single functioning kidney; concomitant use with aliskiren-containing drugs in patients with moderate to severe renal impairment (GFR <60 mL/minute/1.73 m2); extracorporeal treatment leading to contact of blood with negatively charged surfaces; hereditary problems of galactose intolerance, glucose-galactose malabsorption, or congenital lactase deficiency.
Concerns related to adverse effects:
• Angina/MI: Increased angina and/or MI has occurred with initiation or dosage titration of dihydropyridine calcium channel blockers, especially in patients with severe obstructive coronary artery disease in the absence of concurrent beta-blockade.
• Angioedema: At any time during treatment (especially following first dose) angioedema may occur rarely with ACE inhibitors; it may involve the head and neck (potentially compromising airway) or the intestine (presenting with abdominal pain). Black patients and patients with idiopathic or hereditary angioedema or previous angioedema associated with ACE inhibitor therapy may be at an increased risk. Risk may also be increased with concomitant use of mTOR inhibitor (eg, everolimus) or neprilysin inhibitor (eg, sacubitril) therapy. Prolonged frequent monitoring may be required especially if tongue, glottis, or larynx are involved as they are associated with airway obstruction. Patients with a history of airway surgery may have a higher risk of airway obstruction. Aggressive early and appropriate management is critical. Use is contraindicated in patients with a history of angioedema with or without previous ACE inhibitor treatment.
• Cholestatic jaundice: A rare toxicity associated with ACE inhibitors includes cholestatic jaundice, which may progress to fulminant hepatic necrosis; discontinue if marked elevation of hepatic transaminases or jaundice occurs.
• Cough: An ACE inhibitor cough is a dry, hacking, nonproductive one that usually occurs within the first few months of treatment and should generally resolve within 1 to 4 weeks after discontinuation of the ACE inhibitor. Other causes of cough should be considered (eg, pulmonary congestion in patients with heart failure) and excluded prior to discontinuation.
• Hematologic effects: Another ACE inhibitor, captopril, has been associated with neutropenia with myeloid hypoplasia and agranulocytosis; anemia and thrombocytopenia have also occurred. Patients with renal impairment are at high risk of developing neutropenia. Patients with both renal impairment and collagen vascular disease (eg, systemic lupus erythematosus) are at an even higher risk of developing neutropenia. Periodically monitor CBC with differential in these patients.
• Hyperkalemia: May occur with ACE inhibitors; risk factors include renal dysfunction, diabetes mellitus, concomitant use of potassium-sparing diuretics, potassium supplements and/or potassium-containing salts. Use cautiously, if at all, with these agents and monitor potassium closely.
• Hypersensitivity reactions: Anaphylactic/anaphylactoid reactions can occur with ACE inhibitors. Severe anaphylactoid reactions may be seen during hemodialysis (eg, CVVHD) with high-flux dialysis membranes (eg, AN69), and rarely, during low density lipoprotein apheresis with dextran sulfate cellulose. Rare cases of anaphylactoid reactions have been reported in patients undergoing sensitization treatment with hymenoptera (bee, wasp) venom while receiving ACE inhibitors.
• Hypotension/syncope: Symptomatic hypotension with or without syncope can occur with ACE inhibitors (usually with the first several doses); effects are most often observed in volume-depleted patients; correct volume depletion prior to initiation; close monitoring of patient is required especially with initial dosing and dosing increases; blood pressure must be lowered at a rate appropriate for the patient's clinical condition. Although dose reduction may be necessary, hypotension is not a reason for discontinuation of future ACE inhibitor use especially in patients with heart failure where a reduction in systolic blood pressure is a desirable observation.
• Renal function deterioration: Perindopril may be associated with deterioration of renal function and/or increases in BUN and serum creatinine, particularly in patients with low renal blood flow (eg, renal artery stenosis, heart failure) whose GFR is dependent on efferent arteriolar vasoconstriction by angiotensin II; deterioration may result in oliguria, acute renal failure, and progressive azotemia. Small increases in serum creatinine may occur following initiation; consider discontinuation only in patients with progressive and/or significant deterioration in renal function (Bakris 2000).
Disease-related concerns:
• Aortic stenosis: Use with extreme caution in patients with severe aortic stenosis; may reduce coronary perfusion resulting in ischemia.
• Cardiovascular disease: Initiation of therapy in patients with ischemic heart disease or cerebrovascular disease warrants close observation due to the potential consequences posed by falling blood pressure (eg, MI, stroke). Fluid replacement, if needed, may restore blood pressure; therapy may then be resumed. Discontinue therapy in patients whose hypotension recurs.
• Collagen vascular disease: Use perindopril with caution in patients with collagen vascular disease especially with concomitant renal impairment; may be at increased risk for hematologic toxicity.
• Hepatic impairment: Use with caution in patients with hepatic impairment.
• Hypertrophic cardiomyopathy with left ventricular outflow tract obstruction: Use with caution in patients with hypertrophic cardiomyopathy and left ventricular outflow tract obstruction since reduction in afterload may worsen symptoms associated with this condition (AHA/ACC [Ommen 2024]).
• Renal artery stenosis: Use perindopril with caution in patients with unstented unilateral or bilateral renal artery stenosis. When unstented bilateral renal artery stenosis is present, use is generally avoided due to the elevated risk of deterioration in renal function unless possible benefits outweigh risks.
• Renal impairment: Use with caution in patients with mild to moderate renal impairment (CrCl ≥30 mL/minute); not recommended in patients with severe renal impairment (CrCl <30 mL/minute).
Special populations:
• Black patients: ACE inhibitors effectiveness is less in black patients than in non-black patients. In addition, ACE inhibitors cause a higher rate of angioedema in black than in non-black patients.
• Pregnancy: [US Boxed Warning]: Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected.
Other warnings/precautions:
• Surgery: In patients on chronic ACE inhibitor therapy, intraoperative hypotension may occur with induction and maintenance of general anesthesia; use with caution before, during, or immediately after major surgery. Cardiopulmonary bypass, intraoperative blood loss, or vasodilating anesthesia increases endogenous renin release. Use of ACE inhibitors perioperatively will blunt angiotensin II formation and may result in hypotension. However, discontinuation of therapy prior to surgery is controversial. If continued preoperatively, avoidance of hypotensive agents during surgery is prudent (Hillis 2011).

[US Boxed Warning]: Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected. See individual agents.
Amlodipine is present in breast milk (Naito 2015); it is not known if perindopril is present in breast milk. Due to the potential for serious adverse reactions in the breastfeeding infant, the manufacturer's labeling recommends discontinuing breastfeeding or discontinuing therapy. See individual agents.
Blood pressure; renal function and electrolytes; if patient has collagen vascular disease and/or renal impairment, periodically monitor CBC with differential. If doses > perindopril 7 mg/amlodipine 5 mg once daily are required in patients >65 years of age, monitor blood pressure up to 2 weeks following up titration.
Amlodipine: Inhibits calcium ion from entering the “slow channels” or select voltage-sensitive areas of vascular smooth muscle and myocardium during depolarization, a relaxation of coronary vascular smooth muscle and coronary vasodilation; amlodipine directly acts on vascular smooth muscle to produce peripheral arterial vasodilation reducing peripheral vascular resistance and blood pressure.
Perindopril: Prevents conversion of angiotensin I to angiotensin II, increases plasma renin activity, and reduces aldosterone secretion.
See individual agents.
