  • To reduce the risk of cardiovascular death and hospitalization for heart failure with reduced ejection fraction (HFrEF) in adult patients with chronic heart failure. It is more beneficial in patients with left ventricular ejection fraction (LVEF) that is below normal
  • For the treatment of symptomatic heart failure with left ventricular systolic dysfunction in pediatric patients 1 year of age and older

How to take Entresto

  • Take Entresto exactly as your healthcare provider prescribes it
  • Entresto’s usual starting dose is 49 mg/51 mg taken twice a day. Your doctor may start you on a lower starting dose or change your dose during treatment

How does Entresto work?

Entresto is a combination product that contains sacubitril and valsartan. Sacubitril acts as a neprilysin inhibitor. By blocking the enzyme neprilysin, sacubitril prevents the breakdown of natriuretic peptides which helps lower blood pressure. This also causes an accumulation of the protein angiotensin II.

Valsartan is an angiotensin II receptor blocker (ARB) that prevents angiotensin II from binding and causing vasoconstriction (narrowing of your blood vessels), and cardiac stimulation, among other blood pressure-raising effects. Valsartan is used along with sacubitril because it can block the effects of the accumulated angiotensin II.

What are the side effects of Entresto?

Some common side effects of Entresto in clinical trials can include:

  • Hypotension
  • Hyperkalemia
  • Cough
  • Dizziness
  • Lightheadedness

Some serious side effects of Entresto include:

  • Angioedema
  • Worsening kidney disease or function, especially in those with congestive heart failure (CHF)
  • Angioedema (swelling of your face, lips, tongue, and throat) and hypotension (low blood pressure)
  • Allergic reactions – discontinue Entresto immediately and seek medical advice if you have symptoms such as hives, trouble breathing, or swelling of your face, lips, tongue, or throat
  • Increase in potassium levels. Before using potassium supplements or salt substitutes that contain potassium, consult your healthcare provider

You can report any side effects you experience to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

What dosage is recommended for Entresto?

Entresto’s usual starting dose is 49 mg/51 mg taken twice a day. Your doctor may start you on a lower starting dose or change your dose during treatment. Your exact dose will be based on your age, weight, and the condition you are being treated for.

What happens if I take too much Entresto?

Overdose of Entresto will cause side effects such as hypotension, making you feel very lightheaded, dizzy, or tired.

Precautions with Entresto

Entresto is contraindicated if you have any of the following medical conditions:

  • Pregnancy
  • Hypersensitivity to any components of Entresto
  • History of angioedema related to previous angiotensin-converting enzyme inhibitors (ACE inhibitors) or ARBs
  • Hereditary angioedema
  • Do not take Entresto within 36 hours of ACE inhibitors such as lisinopril or ramipril
  • Concomitant use with Tekturna (aliskiren) in patients with diabetes

What other medications interact with Entresto?

When Entresto is taken with other medications, they may interact and change how they work. It may also increase the severity of certain side effects or make them more likely to occur. Make sure your doctor is aware of all the medications you take, including prescription drugs, over-the-counter medications, vitamins, and herbal supplements. Some major drug interactions with Entresto include:

  • Aliskiren – avoid use if you have an eGFR < 60
  • Potassium-sparing diuretics (water pills) – can cause hyperkalemia (high potassium levels)
  • Non-steroidal anti-inflammatory drugs (NSAIDs) – meds such as ibuprofen can increase your risk of kidney problems
  • Lithium – may cause lithium toxicity

What medications are similar to Entresto?

There are other medications to treat heart failure that your healthcare professional can prescribe if Entresto is not the right medication for you. Some FDA-approved alternative treatment options include:

  • Beta-blockers such as carvedilol, metoprolol, and bisoprolol can slow your heart rate and reduce high blood pressure
  • ACE inhibitors to help blood vessels relax and open
  • ARBs such as valsartan and losartan also cause blood vessels to relax and open
  • Neprilysin inhibitors increase the availability of natriuretic peptides helping to dilate blood vessels

Diuretics will help with some heart failure symptoms, but not necessarily improve your heart’s ejection fraction
