To learn more, see the “Side effects explained” section above.

Other warnings

Austedo may not be right for you if you have certain medical conditions or other factors that affect your health. Talk with your doctor about your health history before you take Austedo. The list below includes factors to consider.

Certain heart rhythm conditions that affect your QT interval: Austedo can raise your risk for developing a heart rhythm problem called long QT syndrome. If you already have a condition that affects your heart’s QT interval, Austedo may make your condition worse. Tell your doctor about any heart conditions that you have before you start Austedo treatment.

Allergic reaction: If you’ve had an allergic reaction to Austedo or any of its ingredients, you should not take Austedo. Ask your doctor what other medications are better options for you.

Liver problems: If you have any liver problems, tell your doctor before using Austedo. This drug is cleared from your body by your liver. If your liver isn’t working correctly, your body may not be able to get rid of the drug. This can cause the levels of the drug to build up in your body, which can raise your risk for side effects. If you have certain liver problems, your doctor may recommend a different medication for your condition instead of Austedo.

Low blood levels of magnesium or potassium: If you have low blood levels of magnesium or potassium, taking Austedo may increase your risk of heart rhythm problems. Before prescribing Austedo, your doctor may recommend treatment for your low potassium or magnesium levels first. They may also order blood tests to check these levels during Austedo treatment.

Alcohol and Austedo

Alcohol and Austedo can both make you feel drowsy or tired. Drinking alcohol while you’re taking Austedo can make these side effects worse.

If you drink alcohol, talk with your doctor or pharmacist about how much (if any) is safe for you to drink during your Austedo treatment.

Pregnancy and breastfeeding while taking Austedo

It’s not known whether Austedo is safe to take during pregnancy. It’s also unknown whether it’s safe to take while breastfeeding. This is because studies haven’t found whether the drug passes into breast milk or what effects it may have on a child who’s breastfed.

If you’re pregnant or breastfeeding, or planning to become pregnant or to breastfeed, talk with your doctor before starting Austedo treatment. They may recommend a different treatment option for your condition.

Austedo or Austedo XR can be an effective treatment for chorea that’s related to Huntington’s disease or for tardive dyskinesia. Some people taking Austedo may experience side effects. But in most cases, side effects from this medication are mild.

  • How should I treat side effects if I experience any?
  • Based on my condition, what side effects am I most likely to experience?
  • If I experience side effects from Austedo, what other treatment options are available for my condition?
  • What can I do to lower my risk for side effects with this drug?

Q:

Could other medications that I take raise my risk for certain side effects from Austedo?

Anonymous

A:
