Do Entresto side effects go away after starting?
Many people do see side effects improve after the first days to weeks on Entresto (sacubitril/valsartan), especially if the effects are related to getting used to the medication or to blood pressure changes. Some common early issues—like dizziness or lightheadedness—can lessen as your body adjusts. If side effects persist or worsen, clinicians often adjust the dose or timing, or evaluate for another cause.
Which Entresto side effects are most likely to improve?
Side effects that are often most noticeable early and may improve include:
- Dizziness or lightheadedness (often related to lower blood pressure)
- Tiredness or weakness
Improvement depends on whether the underlying trigger (like blood pressure being too low) is corrected by dose adjustment, hydration status, or other medication changes.
When side effects do not go away (and what to do)
Some Entresto-related problems may not resolve without medical intervention. You should get in touch with your prescriber promptly if you have ongoing or worsening:
- Low blood pressure symptoms (frequent fainting, severe dizziness)
- Signs of kidney problems (reduced urination, unusual swelling)
- High potassium symptoms (muscle weakness or abnormal heart rhythm symptoms)
If you have severe symptoms, don’t wait for a scheduled appointment—seek urgent care.
What should you do if side effects start right away?
Typical next steps your clinician may consider include:
- Checking blood pressure and symptoms
- Reviewing other medicines that can also lower blood pressure or raise potassium
- Doing blood tests for kidney function and potassium after starting or changing dose
- Adjusting the Entresto dose rather than stopping abruptly on your own
What side effects are rare but serious?
Even if many side effects are manageable, you should treat these as urgent:
- Swelling of the face, lips, tongue, or throat, or trouble breathing (possible angioedema)
- Severe allergic-type reactions
- Severe or persistent dizziness/fainting
How long should you wait to see improvement?
There isn’t a single guaranteed timeline, but side effects that improve from “starting up” often do so within the first few weeks. If you’re still having significant side effects after that window, or they’re getting worse, contact your prescriber to discuss dose adjustment or alternatives.
Are there alternatives if side effects persist?
If Entresto is not tolerated, your clinician may consider other heart-failure medicines or different dosing strategies. The right choice depends on why you’re taking Entresto and your blood pressure, kidney function, and potassium levels.
