Altace Overview


Altace is a prescription medication used to treat high blood pressure and congestive heart failure. It is also used to reduce the risk of heart attacks, stroke, and death from cardiovascular (heart or blood vessel) causes.

Altace belongs to a group of drugs called angiotensin converting enzyme (ACE) inhibitors, which relax blood vessels to lower blood pressure and make the heart more efficient.

This medication comes in capsule form and is taken once or twice a day, with or without food. Capsules must be swallowed whole or can be opened and sprinkled on applesauce or mixed in 4 oz. of water or apple juice.

Common side effects of Altace include headache, fatigue, and cough. Altace can also cause dizziness. Do not drive or operate heavy machinery until you know how Altace affects you.

Altace Precautions

Serious side effects have been reported with Altace including:

  • Angioedema (a serious hypersensitivy reaction). Tell your healthcare profession right away if you have signs or symptoms of angioedema, which include:
    • swelling of face, eyes, lips, tongue, larynx and extremities
    • difficulty in swallowing or breathing
    • hoarseness (having difficulty making sounds when trying to speak)
  • Hyperkalemia (high levels of potassium in the blood). This medication may lead to increased levels of potassium, which could lead to side effects such as heart arrhythmias (irregular heartbeat) and nausea.
  • Hypotension (low blood pressure). Excessive perspiration and dehydration may lead to an excessive fall in blood pressure (hypotension). Vomiting or diarrhea may also lead to a fall in blood pressure.
  • Decline in kidney function. Your doctor may need to perform tests to determine the stability of the function of your kidneys, especially in patients who already have kidney dysfunction. This risk is also present when combined with angiotensin receptor blockers (ARBs) or aliskiren.
  • Neutropenia (rare). Report any sign of infection such as sore throat or fever, which may be a sign of neutropenia (a decreased amount of white blood cells).
  • Liver failure (rare). Report any signs or symptoms of hepatic failure, including:
    • yellowing of the skin or eyes
    • nausea
    • vomiting
    • fatigue
    • itching

Do not take Altace if you:

  • have a history of angioedema related to previous treatment with an ACE inhibitor, or a history of angioedema altogether
  • are allergic to Altace or any of this medication's ingredients

Altace Food Interactions

Medications can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of Altace, salt substitutes containing potassium should be avoided.

Inform MD

Before taking Altace, tell your doctor about all of your medical conditions. Especially tell your doctor if you:

  • have a history of angioedema
  • have decreased liver or kidney function
  • are taking any potassium-containing salt substitutes
  • are pregnant or are breastfeeding

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.

Altace and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Altace falls into category D. It has been shown that use of Altace in pregnant women caused some babies to be born with problems. More specifically, it has been shown that use of drugs like Altace during the second and third trimesters of pregnancy harms the unborn baby’s kidneys and even increases the risk of death to the unborn baby. However, in some serious situations, the benefit of using this medication may be greater than the risk of harm to the baby.

Altace and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known whether Altace crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Altace.

Altace Usage

  • Altace comes in capsule form and is given once or twice a day, with or without food.
  • The Altace capsule can also be opened and its contents sprinkled on a small amount (about 4 oz.) of applesauce or mixed in 4 oz. (120 mL) of water or apple juice.

The mixtures can also be prepared and stored for up to 24 hours at room temperature or up to 48 hours under refrigeration.
  • If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of Altace at the same time.
