The dosage of Austedo you’re prescribed may depend on several factors. These include:

  • the type and severity of the condition you’re using Austedo to treat
  • how well your symptoms are improving
  • side effects you may have from Austedo

Austedo comes as a tablet that you swallow. Be sure to swallow Austedo tablets whole. You should not chew, crush, or split the tablets.

You may take Austedo once or twice per day, depending on the dosage you’re prescribed. Try to take the dose at the same time each day. This helps keep a consistent level of the drug in your body over time.

You should take each dose of Austedo with food.

If you miss a dose of Austedo, take the missed dose as soon as you remember. If it’s almost time for your next dose, just skip the one you’ve missed. Then take your usual dose at its regular time. Do not take any extra doses of Austedo to make up for a missed dose.

But if you miss several doses of Austedo in a row, tell your doctor right away. Wait for their instructions before starting Austedo again. If you aren’t sure whether you should take a missed dose or skip it, talk with your doctor or pharmacist.

If you need help remembering to take your dose of Austedo on time, try using a medication reminder. This can include setting an alarm, downloading a reminder app, or setting a timer on your phone. A kitchen timer can work, too.

Do not use more Austedo than your doctor prescribes. Using more than this can lead to serious side effects.
