What side effects are most common with Entresto 24 mg (sacubitril/valsartan)?
Entresto (sacubitril/valsartan) can cause side effects that are typical for blood-pressure and heart-failure medicines. The most commonly reported include:
- Low blood pressure (dizziness, lightheadedness, faint feeling)
- Elevated potassium levels (may not cause symptoms but can show up on blood tests)
- Kidney-related effects (worsening kidney function on labs)
- Cough
- Fatigue/weakness
What serious side effects should you watch for?
Patients are usually advised to seek urgent care for signs of more dangerous reactions, such as:
- Angioedema (swelling of the face, lips, tongue, or throat), which can be life-threatening
- Severe dizziness or fainting from very low blood pressure
- Signs of high potassium such as muscle weakness or abnormal heart rhythm (often identified via blood tests)
- Worsening kidney function symptoms (reduced urination, unusual swelling, rapid weight change)
How does Entresto 24 mg dosing affect side effects?
Changing the dose can change how strongly you feel blood-pressure effects. With a 24 mg starting dose, side effects related to blood pressure (dizziness/lightheadedness) are still possible, especially when:
- You first start treatment
- Your dose is increased
- You also take other medicines that lower blood pressure or affect kidney function
Your clinician typically monitors blood pressure and lab values (potassium and kidney function) after starting and after dose changes.
What labs are monitored because of Entresto’s side effects?
Entresto commonly affects two lab areas that clinicians track:
- Potassium: risk of hyperkalemia (higher than normal potassium)
- Kidney function: possible rise in creatinine or other changes that suggest reduced kidney performance
What drug interactions can increase side effects?
Some combinations raise risk for low blood pressure, kidney problems, or angioedema. Common ones to discuss with a prescriber include:
- ACE inhibitors (must not be taken close together due to angioedema risk)
- Certain blood pressure medicines and diuretics (can increase dizziness/low BP)
- Potassium supplements or potassium-sparing diuretics (can increase hyperkalemia risk)
- NSAIDs (can affect kidney function in some patients)
When should you call your doctor (even if the side effect isn’t “emergency”)?
Call your prescriber promptly if you notice:
- Persistent dizziness/lightheadedness
- New or worsening shortness of breath, extreme fatigue, or swelling
- Symptoms that could relate to abnormal potassium (like unusual muscle weakness)
- Any allergic-type swelling symptoms (even before you know how severe it is)
