Before Using This Medicine
It is essential to inform your doctor about the following conditions to ensure safe treatment:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Describe the allergic reaction you experienced, including the symptoms that occurred.
A history of angioedema, a severe and potentially life-threatening reaction characterized by symptoms such as swelling of the hands, face, lips, eyes, tongue, or throat, difficulty breathing, swallowing problems, or unusual hoarseness.
Kidney disease, as this condition may affect how your body processes the medication.
Dehydration or electrolyte imbalances, as these conditions can impact the safety and efficacy of the treatment.
Concurrent use of a medication containing aliskiren, particularly if you have diabetes or kidney problems, as this combination may increase the risk of adverse effects.
Recent use (within the last 36 hours) of a medication containing sacubitril, as this may interact with the current treatment.
This list is not exhaustive, and it is crucial to disclose all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, as well as any existing health problems, to your doctor and pharmacist. This information will help determine whether it is safe to take this medication in conjunction with your other treatments and health conditions. Never start, stop, or modify the dosage of any medication without consulting your doctor.
Precautions & Cautions
It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. This will help ensure your safety and prevent any potential interactions with other treatments.
When to Expect Results and Precautions
You may need to wait a few weeks to experience the full effects of this medication. In the meantime, be cautious when driving or engaging in activities that require your full attention, as this medication may affect your alertness. To minimize the risk of dizziness or fainting, stand up slowly after sitting or lying down, and be careful when climbing stairs.
Allergies and Interactions
If you are allergic to tartrazine (FD&C Yellow No. 5), consult your doctor before taking this medication, as some products may contain this ingredient. Additionally, if you are taking a salt substitute with potassium, a potassium-sparing diuretic, or a potassium product, discuss this with your doctor. If you are on a low-salt or salt-free diet, also inform your doctor.
Monitoring Your Condition
Regularly check your blood pressure as directed by your doctor, and undergo blood tests as scheduled. This will help your doctor monitor your condition and adjust your treatment plan if necessary.
Rare but Serious Risks
Although rare, new or worsening chest pain can occur after starting this medication or increasing the dose. In some cases, this may lead to a heart attack, particularly in individuals with severe heart blood vessel disease. If you experience any chest pain or discomfort, seek medical attention immediately.
Infection Risk
This medication can cause a decrease in white blood cell count, which may increase your risk of infection. This is more likely to occur in people with kidney problems, especially those with other underlying health conditions. If you develop symptoms of an infection, such as fever, chills, or sore throat, contact your doctor right away.
Interactions with Other Medications and Substances
Before taking any over-the-counter (OTC) products, including cough or cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, or certain natural products or aids, consult your doctor. These substances may interact with your medication and increase your blood pressure. Also, discuss your alcohol consumption with your doctor, as it may affect your treatment.
Staying Safe in Hot Weather and During Physical Activity
Be cautious in hot weather or when engaging in physical activity, as this can lead to fluid loss. Drink plenty of fluids to stay hydrated, and inform your doctor if you experience excessive sweating, vomiting, diarrhea, or loose stools, as these can cause low blood pressure.
Rare but Serious Allergic Reaction
In rare cases, a severe and potentially life-threatening allergic reaction called angioedema can occur. This risk may be higher in Black patients. If you experience any symptoms of an allergic reaction, seek medical attention immediately.
Special Considerations for Older Adults and Breastfeeding Mothers
If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects. If you are breastfeeding, consult your doctor to discuss any potential risks to your baby.
Overdose Information
Overdose Symptoms:
- Severe hypotension (very low blood pressure), possibly leading to shock
- Bradycardia (slow heart rate)
- Tachycardia (fast heart rate)
- Palpitations
- Dizziness, lightheadedness, fainting
- Hyperkalemia (high potassium levels)
- Renal failure
What to Do:
Call 1-800-222-1222 (Poison Control). Seek immediate medical attention. Treatment is supportive and symptomatic. May involve IV fluids for hypotension, vasopressors, atropine for bradycardia. Amlodipine is highly protein-bound and not dialyzable. Benazeprilat is somewhat dialyzable.
Drug Interactions
Contraindicated Interactions
- Aliskiren (in patients with diabetes or renal impairment due to increased risk of hypotension, hyperkalemia, and renal impairment)
- Sacubitril/Valsartan (Entresto) (due to increased risk of angioedema with ACE inhibitors; do not administer within 36 hours of switching from or to an ACE inhibitor)
Major Interactions
- Potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride), potassium supplements, or potassium-containing salt substitutes (increased risk of hyperkalemia)
- NSAIDs (including COX-2 inhibitors) (may reduce antihypertensive effect of benazepril and increase risk of renal impairment, especially in elderly or volume-depleted patients)
- Lithium (increased serum lithium levels and toxicity)
- mTOR inhibitors (e.g., sirolimus, everolimus, temsirolimus) (increased risk of angioedema)
- CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir, clarithromycin) (may increase amlodipine exposure, leading to increased hypotensive effects)
- Dantrolene (intravenous) (risk of hyperkalemia and cardiovascular collapse with amlodipine)
Moderate Interactions
- Other antihypertensive agents (additive hypotensive effects)
- Diuretics (enhanced hypotensive effect, especially initial doses)
- CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin, phenobarbital) (may decrease amlodipine exposure, reducing efficacy)
- Simvastatin (amlodipine may increase simvastatin exposure; limit simvastatin dose to 20 mg daily)
- Cyclosporine, Tacrolimus (amlodipine may increase levels of these immunosuppressants; monitor levels)
- Gold (injectable) (nitritoid reactions, including facial flushing, nausea, vomiting, and hypotension, reported rarely with concomitant ACE inhibitor therapy)
Minor Interactions
- Grapefruit juice (may increase amlodipine exposure, but generally not clinically significant with typical consumption)
- Antacids (may slightly decrease benazepril absorption, but generally not clinically significant)
Monitoring
Baseline Monitoring
Rationale: To establish baseline and assess efficacy of treatment.
Timing: Prior to initiation of therapy
Rationale: To establish baseline and monitor for bradycardia (less common with amlodipine) or reflex tachycardia.
Timing: Prior to initiation of therapy
Rationale: To assess baseline renal function, as benazepril can affect renal hemodynamics.
Timing: Prior to initiation of therapy
Rationale: To assess baseline potassium levels, as benazepril can cause hyperkalemia.
Timing: Prior to initiation of therapy
Rationale: To assess baseline hepatic function, as amlodipine is extensively metabolized by the liver.
Timing: Prior to initiation of therapy (especially if hepatic impairment is suspected)
Routine Monitoring
Frequency: Regularly, e.g., weekly after initiation/dose change, then monthly or every 3-6 months once stable
Target: <130/80 mmHg (or individualized target)
Action Threshold: If BP remains elevated despite maximum dose, consider adding or switching therapy. If BP is too low (symptomatic hypotension), reduce dose.
Frequency: 1-2 weeks after initiation or dose increase, then every 3-6 months, or more frequently in patients with renal impairment or on concomitant nephrotoxic drugs.
Target: Within normal limits or stable from baseline
Action Threshold: Significant increase (e.g., >30% above baseline or >0.5 mg/dL) may indicate renal dysfunction; consider dose reduction or discontinuation.
Frequency: 1-2 weeks after initiation or dose increase, then every 3-6 months, or more frequently in patients with renal impairment, diabetes, or on concomitant potassium-elevating drugs.
Target: 3.5-5.0 mEq/L
Action Threshold: Hyperkalemia (>5.5 mEq/L) requires intervention (e.g., dose reduction, discontinuation, dietary modification).
Symptom Monitoring
- Dizziness or lightheadedness (especially upon standing)
- Swelling of face, lips, tongue, or throat (angioedema)
- Persistent dry cough
- Fatigue or weakness
- Peripheral edema (swelling of ankles/feet)
- Chest pain or palpitations (rare, but report new or worsening symptoms)
Special Patient Groups
Pregnancy
Contraindicated in the 2nd and 3rd trimesters of pregnancy due to the risk of fetal injury and death from the ACE inhibitor component. Discontinue as soon as pregnancy is detected. Exposure during the first trimester is also associated with potential risks.
Trimester-Specific Risks:
Lactation
Both amlodipine and benazepril (and its active metabolite benazeprilat) are excreted into human milk. Use with caution during breastfeeding. Monitor the infant for adverse effects, particularly hypotension.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients. Not recommended for use in children.
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 and titrate slowly, monitoring renal function and blood pressure closely, due to potential for decreased renal function and increased sensitivity to hypotensive effects.
Clinical Information
Clinical Pearls
- This combination is particularly useful for patients who have not achieved adequate blood pressure control with monotherapy or who experience peripheral edema with amlodipine alone (ACEIs can help mitigate CCB-induced edema).
- The benazepril component can cause a persistent dry cough in some patients. If bothersome, discuss with a healthcare provider as an alternative ACEI or a different class of antihypertensive may be considered.
- Patients should be advised to report any signs of angioedema (swelling of face, lips, tongue, or throat) immediately, as this is a serious, potentially life-threatening side effect of ACE inhibitors.
- Avoid potassium supplements or salt substitutes containing potassium unless specifically advised by a healthcare provider, due to the risk of hyperkalemia with benazepril.
- Take consistently at the same time each day, with or without food.
Alternative Therapies
- Other ACE inhibitors (e.g., lisinopril, enalapril, ramipril)
- Other Calcium Channel Blockers (e.g., nifedipine, felodipine, diltiazem, verapamil)
- Angiotensin Receptor Blockers (ARBs) (e.g., losartan, valsartan, candesartan)
- Thiazide diuretics (e.g., hydrochlorothiazide, chlorthalidone)
- Beta-blockers (e.g., metoprolol, carvedilol)
- Direct Renin Inhibitors (e.g., aliskiren)
