Precautions & Cautions
It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication.
Caution with Daily Activities
Until you know how this medication affects you, avoid driving and other tasks that require alertness. To minimize the risk of dizziness or fainting, rise slowly from a sitting or lying down position, and be cautious when climbing stairs.
Monitoring and Follow-Up
Regularly check your blood pressure as directed by your healthcare provider. Additionally, have your blood work and other laboratory tests done as scheduled by your doctor.
Interactions with Other Substances
If you are taking a salt substitute containing potassium, a potassium-sparing diuretic, or a potassium product, consult with your doctor. Similarly, if you are on a low-salt or salt-free diet, discuss this with your doctor.
Over-the-Counter (OTC) Products and Interactions
If you have high blood pressure and are taking this medication, consult with your doctor before using OTC products that may increase blood pressure, such as:
- Cough or cold medications
- Diet pills
- Stimulants
- Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen
- Certain natural products or aids
Alcohol Consumption
Discuss your alcohol consumption with your doctor before drinking.
Precautions in Hot Weather and Physical Activity
Be cautious in hot weather or during physical activity, and drink plenty of fluids to prevent dehydration. Inform your doctor if you experience excessive sweating, fluid loss, vomiting, or diarrhea, as these may lead to low blood pressure.
Effectiveness in Black Patients
This medication may be less effective in lowering blood pressure in Black patients. In some cases, additional medication may be necessary. If you have questions or concerns, discuss them with your doctor.
Risk of Angioedema
A severe and potentially life-threatening reaction called angioedema has been reported. The risk of angioedema may be higher in Black patients.
Special Considerations
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects. If you are breastfeeding, consult with your doctor to discuss potential risks to your baby.
Overdose Information
Overdose Symptoms:
- Severe hypotension (very low blood pressure)
- Dizziness
- Lightheadedness
- Fainting
- Tachycardia (rapid heart rate)
- Bradycardia (slow heart rate)
- Renal failure
What to Do:
Call 911 or your local emergency number immediately. For poison control, call 1-800-222-1222. Treatment is supportive, including intravenous fluids to restore blood pressure. Perindoprilat can be removed by hemodialysis.
Drug Interactions
Contraindicated Interactions
- Aliskiren (in patients with diabetes or moderate to severe renal impairment)
- Sacubitril/valsartan (Entresto) - due to increased risk of angioedema; must not be co-administered within 36 hours of the last dose of sacubitril/valsartan.
Major Interactions
- Potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride) and potassium supplements (increased risk of hyperkalemia)
- Nonsteroidal anti-inflammatory drugs (NSAIDs) - including selective COX-2 inhibitors (may reduce antihypertensive effect, increase risk of renal impairment and hyperkalemia)
- Lithium (increased serum lithium levels and toxicity)
- mTOR inhibitors (e.g., sirolimus, everolimus, temsirolimus) - increased risk of angioedema
- Racecadotril (increased risk of angioedema)
Moderate Interactions
- Diuretics (thiazide or loop) - increased risk of symptomatic hypotension, especially with initial doses
- Other antihypertensives (additive hypotensive effects)
- Antidiabetics (insulin, oral hypoglycemics) - increased risk of hypoglycemia
- Gold (parenteral) - nitritoid reactions (facial flushing, nausea, vomiting, hypotension) have been reported rarely in patients receiving concomitant gold and ACE inhibitors.
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To establish baseline and assess response to therapy.
Timing: Prior to initiation
Rationale: To assess baseline renal function and identify patients at risk for acute kidney injury.
Timing: Prior to initiation
Rationale: To assess baseline potassium levels and identify risk for hyperkalemia.
Timing: Prior to initiation
Routine Monitoring
Frequency: Regularly, especially after dose adjustments, then periodically (e.g., monthly for first few months, then every 3-6 months)
Target: <130/80 mmHg (or individualized target)
Action Threshold: Persistent hypotension (<90/60 mmHg) or uncontrolled hypertension
Frequency: Within 1-2 weeks of initiation or dose increase, then periodically (e.g., every 3-6 months or as clinically indicated)
Target: Stable or within acceptable limits (e.g., <30% increase from baseline creatinine)
Action Threshold: Significant increase in creatinine (>30% from baseline or >0.5 mg/dL), or decline in GFR
Frequency: Within 1-2 weeks of initiation or dose increase, then periodically (e.g., every 3-6 months or as clinically indicated), more frequently in patients at risk for hyperkalemia
Target: 3.5-5.0 mEq/L
Action Threshold: Potassium >5.5 mEq/L
Frequency: Periodically, especially in patients with renal impairment or collagen vascular disease (due to rare risk of neutropenia/agranulocytosis)
Target: Normal
Action Threshold: Significant decrease in white blood cell count
Symptom Monitoring
- Dizziness or lightheadedness (especially with first dose or dose increase)
- Persistent dry cough
- Swelling of face, lips, tongue, throat (angioedema)
- Difficulty breathing or swallowing
- Yellowing of skin or eyes (jaundice)
- Signs of infection (fever, sore throat) - rare
- Muscle weakness or irregular heartbeat (signs of hyperkalemia)
Special Patient Groups
Pregnancy
Contraindicated. Perindopril can cause injury and death to the developing fetus. If pregnancy is detected, discontinue as soon as possible.
Trimester-Specific Risks:
Lactation
Not recommended. Perindopril and its active metabolite perindoprilat are excreted into breast milk. Due to the potential for serious adverse effects in the breastfed infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients. Use is generally not recommended.
Geriatric Use
No overall differences in effectiveness or safety have been observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Start with lower doses (e.g., 2mg once daily) and titrate slowly, especially in those with impaired renal function.
Clinical Information
Clinical Pearls
- Administer perindopril once daily in the morning before a meal, as food decreases the conversion to the active metabolite, perindoprilat.
- Monitor for first-dose hypotension, especially in patients who are volume-depleted (e.g., on diuretics) or have severe heart failure. Consider discontinuing diuretics 2-3 days prior to initiation if possible.
- A persistent dry cough is a common side effect of ACE inhibitors and may necessitate switching to an Angiotensin Receptor Blocker (ARB) if intolerable.
- Educate patients on the signs and symptoms of angioedema and to seek immediate medical attention if it occurs.
- Regularly monitor renal function and serum potassium, especially in patients with pre-existing renal impairment, diabetes, or those on potassium-sparing diuretics or NSAIDs.
Alternative Therapies
- Other ACE inhibitors (e.g., Lisinopril, Enalapril, Ramipril)
- Angiotensin Receptor Blockers (ARBs) (e.g., Valsartan, Losartan, Candesartan)
- Calcium Channel Blockers (CCBs) (e.g., Amlodipine, Nifedipine)
- Thiazide Diuretics (e.g., Hydrochlorothiazide)
- Beta-blockers (e.g., Metoprolol, Carvedilol)
