What Is Entresto?

Entresto (sacubitril and valsartan) is an oral prescription combination drug used to treat adults with heart failure. It belongs to a class of medications called angiotensin receptor-neprilysin inhibitors (ARNis).

Sacubitril is a neprilysin inhibitor. It causes blood vessels to dilate, which lowers blood pressure. Valsartan is an angiotensin II receptor blocker (ARB). Angiotensin II is a hormone. It causes the body to hold salt and water and constricts blood vessels, which increases blood pressure.

Angiotensin II has receptors in the kidneys, heart, blood vessels, brain, and adrenal glands. ARBs block the receptors and lower the hormone’s effects, and therefore reduce blood pressure. ARBs also prevent damage to the kidneys and the heart.

Entresto is available as a tablet. However, pharmacists can compound it into an oral suspension (liquid) for children and adults who cannot swallow.

What Is Entresto Used For?

The Food and Drug Administration (FDA) has approved Entresto for use in adults with chronic heart failure and children 1 year of age and older with symptomatic heart failure.

What Happens If I Overdose on Entresto?

If you think someone may have overdosed on Entresto, contact a healthcare provider or Poison Control Center at 800-222-1222.

It is very important that your doctor check your or your child’s progress at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away.

Do not take this medicine for at least 36 hours before or after you take an ACE inhibitor medicine.

Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position or if you have been taking a diuretic (water pill). Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.

Ask your doctor before you use medicines, supplements, or salt substitutes that contain potassium.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

  • Are pregnant, because this drug can cause injury or death to your baby
  • Have a history of angioedema despite the cause, since valsartan can cause angioedema
  • Are taking angiotensin-converting enzyme (ACE) inhibitors, which increase the risk of angioedema
  • Are hypersensitive to sacubitril, valsartan, or any part of the combination
  • Have diabetes and are also taking a renin inhibitor called Tekturna (aliskiren)

What Other Medications Interact With Entresto?

Entresto may interact with other medications. Before starting Entresto, talk to your healthcare provider about any other prescription or over-the-counter medications you are taking.

The following medications may interact with Entresto:

  • ACE inhibitorsSodium phosphatesLithiumTekturna (aliskiren)

ACE Inhibitors 

ACE (angiotensin-converting enzyme) inhibitors treat high blood pressure and heart failure. ACE inhibitors increase the side effects of Entresto. Notably, the risk of angioedema increases. Your healthcare provider must allow a 36-hour washout period (time between medications) when switching you from or to an ACE inhibitor.

Sodium Phosphates 

Sodium phosphates treat short-term constipation and serve as bowel cleansing drugs for colonoscopy prep. However, taking sodium phosphates with Entresto can increase kidney damage due to the presence of valsartan, an ARB, in Entresto.

Your healthcare provider may stop your medication briefly when you are on sodium phosphates. If you must take them together, stay well hydrated. Your provider should watch your kidneys very closely.

Lithium

Lithium is a medicine that treats bipolar disorder. ARBs may increase lithium levels in the body and therefore cause more side effects. Your provider may have to reduce the dose of your lithium if you have to take Entresto.

Tekturna (Aliskiren)

Tekturna is a renin inhibitor used to lower blood pressure. Entresto should not be taken with Tekturna in people with diabetes.

What Medications Are Similar?

Other medications that treat heart failure, like Entresto, include:

  • Diovan (valsartan)
  • Atacand (candesartan)
  • Altace (ramipril)

Diovan (Valsartan)

Diovan is an ARB. It treats high blood pressure and other heart conditions. Diovan has more side effects than Entresto. It can cause rare reactions like rhabdomyolysis (muscle breakdown), orthostatic hypotension (blood pressure falls when standing up or sitting down), hepatitis (liver inflammation due to infection by a virus), and thrombocytopenia (very low platelet count, which may cause nose and gum bleeds).

Atacand (Candesartan)

Atacand is an ARB that treats high blood pressure and other heart conditions. However, Entresto increases the risk of low blood pressure and increased potassium in the body, whereas Atacand does not. Atacand also has fewer side effects than Entresto.

Altace (Ramipril)

Altace is an ACE inhibitor. It treats heart failure and high blood pressure. It also reduces the risk of stroke, heart attack, and death from heart problems. Ramipril has more side effects, including a more persistent cough than Entresto. It also has more drug-drug interactions. Do not take this at the same time as Entresto.

This is a list of drugs also prescribed for heart failure. It is not a list of drugs recommended to take with Entresto. You should not take these drugs together. Ask your pharmacist or healthcare provider if you have any questions.
