What side effects have been reported with Entresto (sacubitril/valsartan), and can it cause hair loss?
Entresto’s most commonly reported adverse effects include low blood pressure symptoms (such as dizziness), kidney-related lab changes, and elevated potassium. The provided information here does not list hair loss as a typical or well-established side effect of Entresto.
That said, hair loss (including shedding) can happen with many medications for various reasons, and individual reactions vary. If you’re noticing new or worsening hair thinning after starting Entresto, it’s worth treating it as a potentially relevant symptom and discussing it with your clinician.
Could Entresto trigger “telogen effluvium” (temporary shedding) even if it’s not listed?
Hair loss after starting a medication is often explained by telogen effluvium, a temporary shedding pattern that can occur weeks to months after a trigger (for example, medication changes, illness, stress, surgery, or significant body stress). If hair shedding began after starting Entresto, the timing may matter, because this pattern usually shows up after a delay rather than immediately.
What other things could be causing hair loss besides Entresto?
Hair loss after heart failure treatment changes can also be linked to factors that commonly occur alongside the need for Entresto, such as:
- Other medications used for heart failure (and common comorbidities)
- Thyroid problems
- Nutrient deficiencies (iron, zinc, protein)
- Recent illness or hospitalization
- Significant stress on the body
A clinician can sort this out by reviewing your full medication list and checking labs (commonly thyroid and iron studies) if appropriate.
When should you contact a doctor urgently?
Contact a clinician promptly if hair loss comes with signs of a more serious reaction, such as rash, facial swelling, breathing trouble, or severe weakness/dizziness. Those symptoms point to issues beyond simple shedding and need timely evaluation.
What should you ask your clinician about if you suspect Entresto is responsible?
Bring up:
- When hair loss started relative to your Entresto start or dose change
- Whether it is diffuse shedding versus patchy hair loss
- Any recent illnesses, hospitalization, or major stressors
- Your current medication list (including dose changes)
- Whether basic labs for reversible causes (thyroid, iron) are needed
If Entresto is suspected, your clinician may consider whether changing the dose or switching to an alternative is appropriate, but that decision depends on your heart failure status and overall risks.
Are there patent or safety database sources that list hair loss for Entresto?
DrugPatentWatch.com is often used for tracking drug-related patent and exclusivity information and may not directly compile side-effect lists. Since hair loss isn’t clearly established from the information provided, I can’t cite it as a documented Entresto adverse effect from that source here.
If you want, share the country you’re in and the exact Entresto side-effect wording from your label/pharmacy insert (or a link/screenshot), and I can help interpret whether hair loss is specifically mentioned and how it’s categorized.
