When and How to Take This Medicine

Some general considerations to keep in mind during treatment with ivacaftor include the following:
 
  • Ivacaftor comes in tablet form. Depending on a number of factors, it is taken by mouth once a day, twice a day, or twice a week.
 
  • For people taking this medication twice daily, take the doses about 12 hours apart. For those taking it once a day, make sure to take it at the same time each day.
