Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction you experienced, including any symptoms that occurred.
If you have kidney disease, as this may affect how your body processes the medication.
If you are taking a medication that contains aliskiren, particularly if you also have diabetes or kidney problems, as this combination may increase the risk of adverse effects.
If you are breast-feeding, as you should not breast-feed while taking this medication.
This list is not exhaustive, and it is crucial to discuss all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, with your doctor and pharmacist. They will help you determine if it is safe to take this medication with your other medications and health conditions.
Remember, do not start, stop, or change the dose of any medication without first consulting your doctor to ensure your safety.
Precautions & Cautions
When starting this medication, be cautious when performing tasks that require alertness, such as driving, until you understand how it affects you. To minimize the risk of dizziness or fainting, rise slowly from a seated or lying position and exercise caution when navigating stairs.
Regularly monitor your blood pressure as directed by your healthcare provider. Additionally, adhere to the schedule for blood work and other laboratory tests as recommended by your doctor.
Be aware that this medication may rarely cause new or worsening chest pain, particularly when first initiated or when the dosage is increased. In some cases, it may also lead to a heart attack. This risk is potentially higher in individuals with severe heart blood vessel disease. It is crucial to discuss these risks with your doctor.
Before using any over-the-counter (OTC) products that may increase blood pressure, consult with your doctor. These products include cough or cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, and certain natural products or aids.
If you are using a salt substitute containing potassium, a potassium-sparing diuretic, or a potassium product, inform your doctor. Similarly, if you are following a low-salt or salt-free diet, discuss this with your doctor to ensure safe management.
It may take several weeks to experience the full effects of this medication. Before consuming alcohol, consult with your doctor to understand any potential interactions.
In hot weather or during physical activity, be mindful of fluid loss and drink plenty of fluids to stay hydrated. If you experience excessive sweating, fluid loss, vomiting, or diarrhea, notify your doctor, as these conditions may lead to low blood pressure.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
Overdose Information
Overdose Symptoms:
- Profound hypotension (very low blood pressure)
- Bradycardia (slow heart rate)
- Tachycardia (fast heart rate)
- Shock
- Electrolyte imbalances (e.g., hyperkalemia)
- Peripheral vasodilation with reflex tachycardia
What to Do:
Seek immediate medical attention. Call 911 or your local emergency number. For poison control, call 1-800-222-1222. Treatment is supportive and symptomatic. Intravenous fluids and vasopressors may be needed for hypotension. Calcium gluconate may reverse calcium channel blockade effects. Hemodialysis is not effective for amlodipine removal but can remove some valsartan.
Drug Interactions
Contraindicated Interactions
- Aliskiren (in patients with diabetes or renal impairment (eGFR <60 mL/min/1.73 m2))
Major Interactions
- Potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride)
- Potassium supplements
- Salt substitutes containing potassium
- NSAIDs (including selective COX-2 inhibitors) - increased risk of renal impairment and reduced antihypertensive effect
- Lithium (increased serum lithium concentrations and toxicity)
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir, clarithromycin) - increased amlodipine exposure
- Strong CYP3A4 inducers (e.g., rifampin, St. John's Wort) - decreased amlodipine exposure
Moderate Interactions
- Simvastatin (amlodipine increases simvastatin exposure; limit simvastatin dose to 20 mg daily)
- Other antihypertensive agents (additive hypotensive effect)
- Grapefruit juice (may increase amlodipine exposure)
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To establish baseline and guide therapy initiation.
Timing: Prior to initiation
Rationale: Valsartan can cause hyperkalemia. Amlodipine can cause peripheral edema.
Timing: Prior to initiation
Rationale: Valsartan can impair renal function, especially in patients with pre-existing renal impairment or volume depletion.
Timing: Prior to initiation
Rationale: Amlodipine is extensively metabolized by the liver; valsartan is minimally metabolized.
Timing: Prior to initiation
Routine Monitoring
Frequency: Regularly (e.g., weekly initially, then monthly or as clinically indicated)
Target: <130/80 mmHg (individualized based on guidelines and patient comorbidities)
Action Threshold: If BP remains uncontrolled, consider dose adjustment or additional therapy. If hypotensive, reduce dose.
Frequency: Periodically (e.g., every 3-6 months, more frequently in patients at risk for hyperkalemia or with renal impairment)
Target: 3.5-5.0 mEq/L
Action Threshold: If K+ >5.5 mEq/L, consider dose reduction or discontinuation. If K+ <3.5 mEq/L, investigate cause and supplement if needed.
Frequency: Periodically (e.g., every 3-6 months, more frequently in patients with pre-existing renal impairment, heart failure, or on concomitant NSAIDs)
Target: Stable within patient's baseline
Action Threshold: If significant increase in creatinine or decrease in eGFR, investigate cause and consider dose adjustment or discontinuation.
Symptom Monitoring
- Dizziness
- Lightheadedness
- Fainting (syncope)
- Peripheral edema (swelling of ankles/feet)
- Fatigue
- Headache
- Flushing
- Palpitations
- Symptoms of hyperkalemia (muscle weakness, irregular heartbeat, fatigue)
- Signs of angioedema (swelling of face, lips, tongue, throat, difficulty breathing)
Special Patient Groups
Pregnancy
Contraindicated in the second and third trimesters of pregnancy due to the risk of fetal injury and death associated with valsartan. Discontinue as soon as pregnancy is detected.
Trimester-Specific Risks:
Lactation
Not recommended during breastfeeding. Both amlodipine and valsartan are excreted into breast milk in small amounts. Due to the potential for serious adverse effects in the infant (e.g., hypotension, hyperkalemia), 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. Not recommended for use in children.
Geriatric Use
No overall differences in effectiveness or safety were observed between elderly (âĨ65 years) and younger patients. However, greater sensitivity of some older individuals cannot be ruled out. Initiate at the lower end of the dosing range and monitor renal function and electrolytes closely, especially in those with impaired renal function or concomitant conditions.
Clinical Information
Clinical Pearls
- This combination is typically used when monotherapy with either amlodipine or valsartan is insufficient to control blood pressure.
- Take the medication at approximately the same time each day to maintain consistent blood levels.
- Patients should be advised to report any swelling of the hands, ankles, or feet, as peripheral edema is a common side effect of amlodipine.
- Monitor for symptoms of hyperkalemia (e.g., muscle weakness, fatigue, irregular heartbeat) due to the valsartan component, especially in patients with renal impairment or those taking potassium-sparing diuretics or potassium supplements.
- Educate patients on the importance of avoiding potassium-containing salt substitutes without consulting their physician.
- Counsel women of childbearing potential about the risks of fetal exposure and the need to use effective contraception.
Alternative Therapies
- Other Angiotensin Receptor Blockers (ARBs) (e.g., losartan, irbesartan, candesartan)
- Other Calcium Channel Blockers (CCBs) (e.g., nifedipine, felodipine, diltiazem, verapamil)
- ACE Inhibitors (e.g., lisinopril, enalapril, ramipril)
- Thiazide Diuretics (e.g., hydrochlorothiazide, chlorthalidone)
- Beta-blockers (e.g., metoprolol, carvedilol)
- Alpha-blockers (e.g., prazosin, doxazosin)
