Entresto Overview
Entresto (sacubitril-valsartan) is a combination medication that contains two active ingredients working together to support heart health. Sacubitril works by blocking an enzyme that breaks down beneficial compounds in your body, allowing these compounds to help blood vessels relax. Valsartan is an angiotensin receptor blocker (ARB) that helps relax blood vessels and reduce the workload on your heart.
This dual-action approach makes Entresto uniquely effective for treating heart failure with reduced ejection fraction—a condition where your heart doesn't pump blood efficiently. It's also used to manage high blood pressure in patients who may benefit from this combination approach. By reducing strain on your heart and improving blood flow, Entresto may help you feel less fatigued and experience better exercise tolerance.
Entresto has been shown in clinical studies to reduce hospitalizations and improve survival rates in heart failure patients. The medication is taken by mouth, typically twice daily, and works best when combined with other heart failure treatments and lifestyle changes like limiting salt and staying physically active.
Side Effects
Most people tolerate Entresto well, though some experience side effects as their body adjusts to the medication. Common side effects are usually mild and temporary, while serious side effects are rare but require immediate attention.
Common Side Effects
Dizziness or lightheadedness — Your blood pressure may drop temporarily when standing, especially when first starting the medication or increasing your dose.
Low blood pressure (hypotension) — This is expected and monitored by your doctor; it's actually how the medication works to help your heart.
Dry cough — A persistent, non-productive cough may develop and could be bothersome for some patients.
Fatigue or weakness — Some people feel Mounjaro Make You Tired when starting blood pressure medications, though this often improves over time.
High potassium levels — Your body may retain more potassium, which your doctor monitors through blood tests.
Kidney function changes — Some patients experience slight changes in kidney function, requiring occasional blood work monitoring.
Serious Side Effects
Severe allergic reaction — Swelling of the face, lips, or throat requires immediate emergency care.
Angioedema — Unusual swelling in various body parts; this is a known risk with this medication class.
Dangerously low blood pressure — Severe dizziness, fainting, or difficulty breathing may indicate your blood pressure has dropped too much.
Kidney failure — Though rare, severe kidney problems can develop; watch for changes in urination or swelling.
Hyperkalemia — Dangerous potassium levels can cause irregular heartbeat or muscle weakness.
When to Seek Medical Attention
Contact your doctor right away if you experience severe dizziness, fainting, unusual swelling, difficulty breathing, or chest pain. If you notice changes in urination, persistent dry cough that interferes with daily life, or signs of infection, call your healthcare provider. For emergency symptoms like severe allergic reactions, call 911 or go to the nearest emergency room. Your doctor will adjust your dose or consider alternatives if side effects become intolerable.

Drug Interactions
Entresto can interact with various medications and supplements, potentially affecting how well it works or increasing side effect risks. Always inform your doctor and pharmacist about all medications, vitamins, and herbal products you take.
ACE Inhibitors and Other ARBs
Taking Entresto with another blood pressure medication in these classes increases the risk of dangerously low blood pressure, high potassium, and kidney problems. Your doctor will not prescribe these together and will ensure you've waited appropriate time after stopping one before starting Entresto.
NSAIDs (Ibuprofen, Naproxen)
These pain relievers can reduce how well Entresto works and increase the risk of kidney damage, especially with long-term use. Pain relief options like acetaminophen are typically safer, but discuss any pain management with your doctor.
Potassium Supplements and Potassium-Sparing Diuretics
These medications increase potassium levels in your blood, and combining them with Entresto may cause dangerous hyperkalemia. Your doctor monitors potassium levels carefully and may recommend dietary potassium restrictions.
Lithium
Entresto can increase lithium levels in your body, potentially causing lithium toxicity. If you take lithium for mood disorders, your doctor will monitor lithium levels frequently and may adjust your dose.
NSAIDs and Diuretics Together
Using Entresto with both NSAIDs and water pills significantly increases kidney damage risk. Your doctor carefully evaluates this combination and may recommend safer alternatives.
Aliskiren (Tekturna)
Combining Entresto with this direct renin inhibitor increases risks of low blood pressure, high potassium, and kidney problems. These medications are not typically used together.
