Imagine taking a life-saving medication for heart failure, only to experience unexpected symptoms that leave you worried about your health. Sacubitril/valsartan (brand name Entresto) is a breakthrough medication for heart failure, but like all treatments, it comes with potential side effects that patients need to understand.
This guide explores the known side effects of sacubitril/valsartan, how they impact different patient groups and actionable strategies for managing them effectively.

Overview of Sacubitril/Valsartan
Sacubitril/valsartan (Entresto) is a combination medication used to treat certain types of heart failure. It combines two drugs: sacubitril, a neprilysin inhibitor, and valsartan, an angiotensin receptor blocker (ARB).
How Does it Work?
Sacubitril increases levels of peptides that help dilate blood vessels and reduce sodium retention, while valsartan blocks the effects of angiotensin II, leading to vasodilation and reduced blood pressure. Together, they improve heart function and reduce the risk of hospitalization and death in patients with heart failure.
Approved Uses and Benefits
The U.S. Food and Drug Administration (FDA) has approved sacubitril/valsartan for treating heart failure with reduced ejection fraction (HFrEF) in adults. Clinical studies have shown that it can improve symptoms, reduce hospitalizations, and increase survival rates in patients with HFrEF.
The Side Effects of Sacubitril/Valsartan
While sacubitril/valsartan (Entresto) offers significant benefits for heart failure patients, it's important to be aware of potential side effects. Understanding these effects can help patients and healthcare providers manage them effectively.
Common Side Effects
Commonly reported side effects include:
- Dizziness: This may occur due to lowered blood pressure.
- Cough: A persistent dry cough has been reported in some people.
- Elevated potassium levels (hyperkalemia): High potassium blood levels can lead to muscle weakness or irregular heartbeat.
- Kidney function changes: Monitoring is essential to detect any impairment.
Cardiovascular Side Effects
Some patients may experience cardiovascular-related side effects:
- Low blood pressure (hypotension): This can cause dizziness or fainting.
- Irregular heartbeat: May manifest as palpitations or arrhythmias.
Respiratory and Fatigue Symptoms
Respiratory issues and fatigue may also occur:
- Shortness of breath: Difficulty breathing during daily activities.
- Extreme tiredness: Persistent fatigue that is not relieved by rest.
Neurological and Cognitive Symptoms
Neurological side effects may include:
- Confusion: Difficulty concentrating or disorientation.
Muscular and Gastrointestinal Side Effects
Muscular and gastrointestinal symptoms can be present:
- Muscle weakness
- Nausea
- Abdominal pain
Allergic Reactions and Other Symptoms
Allergic reactions and other symptoms to watch for include:
- Allergic reaction (rash, swelling): Skin rash or swelling of the face, lips, or tongue.
- Hives: Raised, itchy welts on the skin.
- Weight gain (potential fluid retention): Sudden increase in weight due to fluid buildup.
Rare but Serious Side Effects
Though less common, these side effects require immediate medical attention:
- Angioedema: Symptoms of angioedema include swelling of the face, lips, tongue, or throat, which can be life-threatening.
- Severe Kidney Damage or Failure: Significant decline in kidney function, leading to potential kidney failure.
Consult your healthcare provider if you experience any of these side effects. They can provide guidance on managing symptoms and determine if adjustments to your treatment plan are necessary.
Managing Sacubitril/Valsartan Side Effects
Managing side effects involves regular monitoring and lifestyle adjustments.
General Management Tips
Side effects may be managed by strategies such as:
- Monitoring symptoms with regular check-ups: Regular visits to your healthcare provider to track your health.
- Staying hydrated and maintaining electrolyte balance: Drinking adequate fluids and monitoring electrolyte levels.
Specific Strategies for Common Side Effects
Addressing specific side effects includes:
- Dealing with dizziness or low blood pressure: Standing up slowly to prevent lightheadedness.
- Managing hyperkalemia through dietary adjustments: Avoid high-potassium foods as your healthcare provider advises.
Special Considerations for Specific Patient Groups
Sacubitril/valsartan affects individuals differently based on age, kidney function, and pregnancy or breastfeeding status.
Elderly Patients
Older adults may be more sensitive to the effects of sacubitril/valsartan, particularly regarding blood pressure and kidney function.
- Increased Risk of Hypotension: Elderly patients are more prone to low blood pressure, which can cause dizziness or fainting.
- Monitoring Kidney Function: Regular kidney function tests are important, as older adults may have decreased kidney performance.
- Dosage Adjustments: Healthcare providers may start elderly patients on a lower dose and adjust as needed.
Patients with Renal Impairment
Individuals with kidney problems require careful monitoring when taking sacubitril/valsartan.
- Risk of Worsening Kidney Function: The medication can affect kidney performance, necessitating regular blood tests.
- Hyperkalemia Concerns: Elevated potassium levels are more likely in patients with kidney issues.
- Dose Considerations: Lower starting doses may be appropriate, with adjustments based on tolerance and lab results.
Pregnant or Breastfeeding Women
Sacubitril/valsartan has an FDA black box warning for fetal toxicity and is typically not recommended during pregnancy or breastfeeding.
- Pregnancy Risks: The medication can harm fetal development, especially in the second and third trimesters.
- Breastfeeding Concerns: It's unclear if the drug passes into breast milk; therefore, it's advised to avoid use while nursing.
- Alternative Treatments: Women who are pregnant or planning to become pregnant should discuss alternative medication options with their healthcare provider.
Comparing Sacubitril/Valsartan Side Effects to Other Medications
When considering treatment options for heart failure, it's helpful to compare the side effect profiles of sacubitril/valsartan with other commonly prescribed medications like ACE inhibitors and ARBs.
ACE Inhibitors vs. ARBs vs. Sacubitril/Valsartan
While all three classes of medications aim to improve heart failure outcomes, their side-effect profiles differ:
- Hypotension (Low Blood Pressure): Sacubitril/valsartan has been associated with a higher incidence of hypotension compared to ACE inhibitors and ARBs.
- Hyperkalemia (High Potassium Levels): The risk of elevated potassium levels is similar across all three medication classes.
- Renal Impairment: All three classes of medications can affect kidney function; however, studies suggest that sacubitril/valsartan may have a comparable or slightly better renal safety profile.
- Cough: ACE inhibitors are more likely to cause a persistent dry cough, a side effect less commonly seen with sacubitril/valsartan and ARBs.
- Angioedema: The occurrence of angioedema is relatively low with sacubitril/valsartan, especially when not used concurrently with ACE inhibitors.
Discuss these medications' efficacy and risks vs. benefits with your healthcare provider to select the best option for your condition.
Weighing Benefits Against Risks in Heart Failure Treatment
Sacubitril/valsartan has demonstrated superior efficacy in reducing cardiovascular mortality and heart failure hospitalizations compared to ACE inhibitors. However, the potential for side effects like hypotension necessitates careful patient selection and monitoring.
Healthcare providers should assess individual patient profiles to determine the most appropriate therapy.
Long-Term Use and Quality of Life
Long-term management of heart failure with sacubitril/valsartan involves monitoring and lifestyle adjustments to maintain quality of life.
How Patients Adapt to Side Effects Over Time
Many side effects, such as dizziness or fatigue, may lessen as the body adjusts to the medication. Regular follow-ups allow healthcare providers to make necessary adjustments to the treatment plan.
The Importance of Balancing Treatment Benefits with Manageable Risks
The goal of treatment is to improve heart function and reduce symptoms while minimizing side effects. Open communication with healthcare providers ensures that any concerns are addressed promptly, leading to better adherence and outcomes.
Always consult your healthcare provider for personalized medical advice regarding sacubitril/valsartan.
