Entresto is not commonly linked to hair loss, with no strong clinical evidence supporting this side effect.
Understanding Entresto and Its Primary Effects
Entresto is a prescription medication widely used to manage heart failure. It combines two active ingredients: sacubitril and valsartan. Sacubitril works by inhibiting neprilysin, an enzyme responsible for breaking down beneficial peptides that help relax blood vessels, while valsartan blocks angiotensin II receptors, reducing blood pressure and strain on the heart. Together, they improve heart function and reduce the risk of hospitalization or death related to heart failure.
This medication has revolutionized heart failure treatment since its approval by the FDA in 2015. Patients often experience improved symptoms such as reduced shortness of breath, increased energy levels, and better exercise tolerance. However, like all medications, Entresto comes with potential side effects that patients and healthcare providers monitor carefully.
Common Side Effects of Entresto
Side effects associated with Entresto primarily relate to its cardiovascular actions and influence on kidney function. The most frequently reported include:
- Low blood pressure (hypotension): Feeling dizzy or lightheaded when standing up.
- Elevated potassium levels (hyperkalemia): Can cause muscle weakness or irregular heartbeat.
- Cough: Though less common than with ACE inhibitors.
- Dizziness or fatigue: Especially during the initial weeks of therapy.
- Kidney function changes: Sometimes requiring dose adjustments.
Notably absent from this list is hair loss. This absence raises questions about whether Entresto could cause hair thinning or shedding indirectly or rarely.
The Link Between Medications and Hair Loss
Hair loss, medically known as alopecia, can be triggered by various factors including genetics, hormonal imbalances, stress, nutritional deficiencies, and certain medications. Drug-induced hair loss typically occurs through two main mechanisms:
- Anagen effluvium: Rapid shedding during the growth phase of hair follicles, often caused by chemotherapy drugs.
- Telogen effluvium: Premature shifting of hair follicles into the resting phase due to physical or emotional stress, illness, or side effects from drugs like beta-blockers or anticoagulants.
Medications commonly implicated in hair loss include chemotherapy agents, blood thinners, antidepressants, beta-blockers, retinoids, and some hormonal therapies.
Can Heart Failure Medications Cause Hair Loss?
Certain cardiovascular drugs have been reported to cause hair thinning in rare cases. For example:
- Beta-blockers: Sometimes linked to telogen effluvium.
- ACE inhibitors: Occasionally associated with hair loss but very uncommon.
- Diuretics: May cause nutritional deficiencies leading to hair thinning if not monitored.
Given that Entresto contains valsartan (an angiotensin receptor blocker or ARB), it’s relevant to examine whether ARBs are associated with hair loss.
The Evidence on Entresto and Hair Loss
Current clinical studies and post-marketing surveillance data do not list hair loss as a recognized adverse effect of Entresto. The prescribing information provided by pharmaceutical companies does not mention alopecia or hair thinning as a side effect.
A review of patient forums and anecdotal reports shows very few isolated cases where patients have reported hair thinning after starting Entresto. However, these cases lack strong scientific backing and may be confounded by other factors such as underlying illness, nutritional status, stress from chronic disease, or concurrent medications.
Valsartan’s Role in Hair Health
Valsartan itself has a very low incidence of causing hair loss. Some ARBs have been studied for their potential benefits in improving scalp blood flow due to vasodilation effects, which theoretically could promote healthier hair follicles rather than harm them.
In rare instances where ARBs might contribute to telogen effluvium, it’s usually reversible upon discontinuation of the drug. Such cases remain exceptional rather than typical.
Sacubitril’s Impact on Hair Growth
Sacubitril is a neprilysin inhibitor designed to increase levels of natriuretic peptides. These peptides primarily affect cardiovascular function but have no known direct influence on hair follicle cycling or growth patterns.
No research currently links neprilysin inhibition with hair loss or scalp conditions.
Other Factors That Could Explain Hair Loss in Patients Taking Entresto
Hair loss in patients prescribed Entresto may stem from factors unrelated to the drug itself:
- Chronic illness: Heart failure can stress the body profoundly, triggering telogen effluvium.
- Nutritional deficiencies: Poor appetite or malabsorption due to illness can lead to low levels of iron, zinc, biotin, or vitamins essential for hair health.
- Concurrent medications: Patients might be taking other drugs known for causing hair thinning (e.g., diuretics, anticoagulants).
- Aging: Natural age-related hair thinning is common in the typical demographic prescribed Entresto.
- Stress: Both emotional and physical stress can precipitate temporary hair loss.
These variables often complicate pinpointing the exact cause of hair changes in individuals managing complex health conditions.
A Closer Look: Reported Side Effects vs Actual Incidence
| Side Effect | Reported Frequency (%) | Relation to Hair Loss? |
|---|---|---|
| Hypotension (Low Blood Pressure) | 10-15% | No direct link |
| Cough | 5-10% | No link |
| Dizziness/Fatigue | 7-12% | No link |
| Elevated Potassium Levels (Hyperkalemia) | 4-8% | No link |
| Alopecia (Hair Loss) | <0.1% (rare anecdotal) | No established causal relationship |
This table highlights that while common side effects are well documented with measurable frequencies, alopecia remains extremely rare if reported at all during Entresto therapy.
Treatment Options for Medication-Related Hair Loss If it Occurs
Although rare with Entresto, if drug-induced telogen effluvium is suspected:
- Nutritional supplementation: Correct deficiencies in iron, zinc, biotin, vitamin D, or protein intake.
- Mild topical treatments: Minoxidil may help stimulate regrowth in some cases but should be used under guidance.
- Lifestyle adjustments: Reducing stress through relaxation techniques supports overall hair health.
- Cessation or substitution: If another drug is responsible for shedding (e.g., diuretics), your doctor might suggest alternatives.
- Patience and monitoring: Telogen effluvium often resolves within months once triggers are removed.
This balanced approach addresses both root causes and symptomatic relief without compromising heart treatment effectiveness.

Frequently Asked Questions
Does Entresto Cause Hair Loss in Patients?
Entresto is not commonly associated with hair loss. There is no strong clinical evidence linking it to hair thinning or shedding. Most side effects relate to cardiovascular or kidney function rather than hair health.
Can Entresto Indirectly Lead to Hair Loss?
While Entresto itself does not cause hair loss, factors like stress from heart failure or other medications might contribute indirectly. However, Entresto’s primary effects do not include mechanisms known to trigger alopecia.
Are There Any Reports of Hair Loss as a Side Effect of Entresto?
Hair loss is notably absent from the common and rare side effects reported for Entresto. Patients and healthcare providers have not identified hair thinning as a typical concern during treatment.
How Does Entresto Compare to Other Heart Medications Regarding Hair Loss?
Unlike some beta-blockers or anticoagulants that can cause hair loss, Entresto’s components (sacubitril and valsartan) have no established link to alopecia. Its side effect profile focuses mainly on blood pressure and kidney-related issues.
What Should I Do If I Experience Hair Loss While Taking Entresto?
If you notice hair loss while on Entresto, consult your healthcare provider. They can help determine if other factors or medications are responsible and suggest appropriate evaluation or treatment options.
The Bottom Line – Does Entresto Cause Hair Loss?
After reviewing scientific data, clinical trial results, pharmacological mechanisms, and patient reports:
The evidence does not support a causal link between Entresto use and hair loss.
While isolated anecdotes exist online suggesting otherwise, these lack sufficient proof and are likely influenced by other factors such as underlying illness severity or concurrent medications.
Patients prescribed Entresto should feel reassured that this life-saving medication is unlikely to impact their hair health directly. However, any unexpected changes in hair volume or texture warrant medical evaluation to rule out treatable causes unrelated to their heart failure therapy.
Maintaining open communication with healthcare providers ensures both cardiac stability and overall wellness remain priorities throughout treatment.
