What does it do?

Sacubitril and valsartan is used to treat heart failure. It reduces excess fluid in your body and relaxes blood vessels, which makes it easier for your heart to pump blood around your body.

How should you take it?

Take sacubitril and valsartan regularly as directed with a glass of water. You can take it with or without food.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with sacubitril and valsartan including:

  • anti-inflammatories, such as diclofenac (e.g. Voltaren®), ibuprofen (e.g. Nurofen®), or aspirin (e.g. Disprin®, in doses used for pain relief). These can also be found in some cold and flu medicines (e.g. Nurofen Cold and Flu®).
  • potassium supplements (e.g. Span K®)

Tell your health professional about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
