What side effects can Entresto (sacubitril/valsartan) cause?
Entresto’s most common side effects are typically related to blood pressure changes and the medication’s effects on the heart, kidneys, and electrolytes. Patients may experience:
- Low blood pressure (dizziness, lightheadedness)
- High potassium levels (hyperkalemia)
- Kidney-related changes (worsening renal function in some people)
- Cough
- Fatigue or weakness
Some people are also monitored for lab abnormalities such as worsening kidney function and electrolyte shifts, especially potassium.
Which side effects are most concerning and need urgent attention?
Stop and seek urgent medical care if symptoms suggest serious reactions, including:
- Signs of angioedema (swelling of face, lips, tongue, or throat; trouble breathing). This is a known risk with drugs in this class and can be life-threatening.
- Severe allergic-type reactions.
- Very fast/worsening dizziness or fainting (could indicate dangerously low blood pressure).
- Symptoms consistent with significant high potassium (for example, new weakness or heart-rhythm symptoms).
If you have a history of angioedema, especially with similar medicines, your clinician may consider that a red flag.
Who is at higher risk for kidney problems or high potassium on Entresto?
Risk tends to be higher in people who already have conditions or take medicines that affect kidney function and potassium, such as:
- Chronic kidney disease
- Dehydration or volume depletion
- Use of other agents that raise potassium (your clinician may adjust or avoid combinations)
- Advanced heart failure or recent dose changes
Clinicians often check blood pressure and labs (kidney function and potassium) after starting and during dose changes.
What about cough or breathing issues from Entresto?
A cough can happen with Entresto. If coughing is persistent or comes with breathing trouble, tell your clinician promptly, since other causes can look similar to medication side effects, and angioedema is a critical condition to rule out if swelling or breathing issues occur.
How do patients usually manage common side effects like low blood pressure?
Low blood pressure is one of the more common issues. Management often involves:
- Checking home blood pressure readings
- Adjusting timing with meals and other blood pressure medicines
- Dose adjustments by the prescribing clinician
- Addressing dehydration (for example, if a person is under-eating or has had vomiting/diarrhea)
Do not adjust the dose on your own. Call your clinician if dizziness, fainting, or consistently low readings occur.
Does Entresto differ from other heart failure drugs in side effects?
Entresto is a different class from ACE inhibitors and ARBs, and it has its own side-effect profile, including the angioedema risk classically associated with neprilysin inhibition. Because it also contains an ARB (valsartan), it can still affect kidney function and potassium like other medicines that act on the renin-angiotensin system.
Are there drug interaction issues that can worsen side effects?
Yes. Side effects can be amplified by combinations that affect kidney function, potassium levels, or blood pressure. Tell your clinician about all medications and supplements, especially:
- Potassium supplements or salt substitutes
- Other blood pressure or heart medications
- NSAIDs (can affect kidney function)
- Any previous reactions to similar medicines
Your clinician can then decide whether to avoid certain combinations or monitor more closely.
