What Perindopril is and how it works
Uses, formulations, monitoring, and supply rules can differ by patient, product, and country. Follow the exact local product information and professional advice.
Mechanism of action: how Perindopril works
Perindopril is an angiotensin-converting enzyme (ACE) inhibitor. It blocks the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, leading to vasodilation, reduced aldosterone secretion, and decreased blood pressure. This mechanism also reduces cardiac workload and helps protect the kidneys in patients with hypertension or diabetes. (1)
What Perindopril is used for
Hypertension (high blood pressure)
FDA-approved (as Aceon in the US), alone or combined with other antihypertensives. (2) (3)
Stable coronary artery disease — to reduce the risk of cardiovascular death or non-fatal heart attack
FDA-approved (as Aceon in the US) for this specific risk-reduction use. (2) (3)
Heart failure (outside the United States)
Approved in many countries (where perindopril is marketed as Coversyl) for heart failure, but this is NOT part of the FDA-approved US (Aceon) label. If you are being treated for heart failure with perindopril, confirm with your prescriber which country's approval and product applies to you. (2) (3)
Before taking Perindopril
Do not take / not appropriate for
- History of angioedema related to previous ACE inhibitor therapy, hereditary or idiopathic angioedema, pregnancy, hypersensitivity to Perindopril or any ACE inhibitor, and severe renal impairment (especially with dialysis using high-flux membranes). (Contraindication) (2)

Procedures and treatment changes
Tell the treating team before surgery, procedures, or any medicine change. Do not alter treatment without the responsible clinician. (2) (3)
Missed dose
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose—do not take an extra dose. Resume your regular schedule.
Overdose
Symptoms of overdose may include severe dizziness, fainting, or very slow heartbeat. Seek emergency medical attention or call your local poison control center immediately. (2) (3)
Side effects
Side effects and their urgency vary; report severe, persistent, or concerning symptoms to a healthcare professional.
Dry, persistent cough
Incidence: Common (about 12% in hypertension trials)
Dizziness
Incidence: Common (about 8% in hypertension trials)
Back pain
Incidence: Common (about 6% in hypertension trials)
Low blood pressure (hypotension)
Incidence: Common, particularly in coronary artery disease patients
Serious warnings
BOXED WARNING (FDA) — serious
Symptoms: BOXED WARNING (FDA): Drugs that act directly on the renin-angiotensin system, including perindopril, can cause injury and death to the developing fetus. When pregnancy is detected, perindopril should be discontinued as soon as possible under medical guidance. This is an FDA boxed warning, the strongest safety warning the FDA requires; it has been checked and added here because the clinician database recorded fetal-harm risk only as ordinary warning text without boxed-warning flagging.
Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2) (3)
Monitor for signs of angioedema (swelling of face, lips, tongue, or throat) — serious
Symptoms: Monitor for signs of angioedema (swelling of face, lips, tongue, or throat). May increase potassium levels—monitor blood tests regularly. Use caution if you have kidney or liver impairment. May cause dizziness; avoid driving or operating machinery until you know how it affects you.
Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2) (3)
Contraindications recorded in the clinician database — serious
Symptoms: Contraindications recorded in the clinician database: Contraindications: History of angioedema related to previous ACE inhibitor therapy, hereditary or idiopathic angioedema, pregnancy, hypersensitivity to Perindopril or any ACE inhibitor, and severe renal impairment (especially with dialysis using high-flux membranes). Precautions: Use with caution in patients with renal artery stenosis, aortic stenosis, hypertrophic cardiomyopathy, electrolyte disturbances, or those on diuretics.
Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2) (3)
Interactions
| Medicine or test | Effect | Action |
|---|---|---|
| Recorded interactions | Perindopril may interact with other blood pressure medications, diuretics, potassium supplements, lithium, NSAIDs, and certain diabetes medicines. These interactions can increase the risk of side effects such as high potassium, kidney problems, or low blood pressure. Always inform your healthcare provider about all medications and supplements you are taking. | (1) |
Pregnancy, breastfeeding, kidney/liver function, age
Pregnancy
This is covered by the FDA boxed warning above: drugs that act directly on the renin-angiotensin system, including perindopril, can cause injury and death to the developing fetus. When pregnancy is detected, perindopril should be discontinued as soon as possible under medical guidance. The UK/EU product information adds that exposure during the second and third trimesters is specifically linked to fetal harm (reduced kidney function, low amniotic fluid, delayed skull bone formation) and newborn complications (kidney failure, low blood pressure, high potassium); if exposure occurred from the second trimester onward, ultrasound checks of fetal kidney function and skull are recommended, and newborns should be closely monitored for low blood pressure. (2) (3)
Breastfeeding
The UK/EU product information states that because no information is available on perindopril use during breastfeeding, perindopril is not recommended while breastfeeding, and an alternative treatment with a better-established safety profile is preferable — especially while nursing a newborn or preterm infant. Discuss feeding options with your doctor. (2) (3)
Children
Frequency: Not applicable. Weight Based: Not recommended for pediatric use. Max Daily Dose: Not applicable. Max Single Dose: Not applicable. Age Restrictions: Safety not established in children (2) (3)
Renal_impairment
UK/EU product information: dosage adjustment in renal impairment is desirable and depends on the degree of impairment (creatinine clearance); patients on hemodialysis should take their dose after the dialysis session. For hepatic impairment, no dosage adjustment is generally necessary — perindopril clearance is reduced by about half in cirrhosis, but the amount of the active metabolite (perindoprilat) formed is not reduced, so no dose change is required; the clinician database separately lists severe renal impairment on high-flux dialysis membranes as a contraindication, which is retained here. (2) (3)
Hepatic_impairment
UK/EU product information: dosage adjustment in renal impairment is desirable and depends on the degree of impairment (creatinine clearance); patients on hemodialysis should take their dose after the dialysis session. For hepatic impairment, no dosage adjustment is generally necessary — perindopril clearance is reduced by about half in cirrhosis, but the amount of the active metabolite (perindoprilat) formed is not reduced, so no dose change is required; the clinician database separately lists severe renal impairment on high-flux dialysis membranes as a contraindication, which is retained here. (2) (3)
Monitoring
(2) (3)Storage
Store perindopril tablets at 20-25°C (68-77°F) and protect from moisture, in the original container, out of reach of children.

Professional information
Clinician-facing context only. This section does not replace current product labeling.
General
Indication: Recorded indication
Dose summary: Initial dose is 4 mg once daily; may be increased to 8 mg once daily based on blood pressure response.
Renal context: UK/EU product information: dosage adjustment in renal insufficiency is desirable, depending on the degree of impairment (creatinine clearance); patients on hemodialysis should take their dose after the dialysis session. The clinician database separately lists severe renal impairment on high-flux dialysis membranes as a contraindication. (1) (3)
Hepatic guidance
UK/EU product information: no dosage adjustment is generally necessary in hepatic impairment. Perindopril kinetics are altered in cirrhosis (hepatic clearance of the parent molecule is reduced by about half), but the quantity of the active metabolite perindoprilat formed is not reduced, so no dose adjustment is required on that basis.
Frequently asked questions
How long does it take for Perindopril to start working?
Perindopril begins to lower blood pressure within a few hours, but it may take several weeks to see the full effect. Continue taking it as prescribed, even if you do not notice immediate changes.
Can I take Perindopril if I am pregnant or breastfeeding?
Perindopril should not be used during pregnancy as it can harm the unborn baby. If you become pregnant, seek medical advice promptly, and let the clinician you see advise on whether to continue or stop Perindopril. It is not recommended during breastfeeding.
What should I do if I develop a persistent cough while taking Perindopril?
A dry, persistent cough is a known side effect of ACE inhibitors like Perindopril. If the cough is bothersome, talk to your doctor. They may recommend an alternative medication.
Can I drink alcohol while taking Perindopril?
Alcohol can enhance the blood pressure-lowering effect of Perindopril and increase the risk of dizziness or fainting. Limit alcohol intake and discuss with your doctor.
Is it safe to take Perindopril with other blood pressure medications?
Perindopril is sometimes used with other blood pressure medicines, but your doctor will monitor you closely for side effects. Always inform your healthcare provider about all medications you are taking.
What foods should I avoid while taking Perindopril?
Avoid potassium-rich foods or salt substitutes containing potassium unless advised by your doctor, as Perindopril can increase potassium levels.
What should I do if I experience swelling of my face or tongue?
Swelling of the face, lips, tongue, or throat (angioedema) is a serious side effect. Seek emergency medical attention immediately — the treating team will manage whether to continue or stop perindopril as part of your emergency care.
What happens if I take too much Perindopril?
Taking too much Perindopril can lead to severe hypotension (low blood pressure), dizziness, fainting, and potentially kidney problems. If you suspect an overdose, seek immediate emergency medical attention. Do not try to self-treat the symptoms. Prompt professional medical evaluation is crucial to manage potential complications effectively and safely.
Is Perindopril safe during pregnancy?
Perindopril is generally not recommended during pregnancy, especially in the second and third trimesters, due to potential risks to the developing fetus.
