The effects of CFTR modulators only last for as long as the medication is in your system. Therefore, you need to take the medication every 12 hours, or as your care team prescribes.
“After 33 years of living with cystic fibrosis, I thought I knew my body pretty well. Since I started on Symdeko®, I have noticed that my body is different, and I need to re-learn how to interpret my symptoms.” -- Aimee Lecointre, adult with CF, from the CF Community Blog
You may experience side effects when you take any medication. When discussing any new medications or changes in dosages for medications you are already taking, be sure to ask your care team about:
- Any potential side effects.
- Which side effects might be more serious than others.
- How long they might last.
- When to talk to your care team if side effects don't go away or if they interfere with your quality of life.
- Any potential drug interactions.
Let your care team know if you feel any side effect that bothers you or makes it hard for you to continue taking this medication as prescribed. Your care team can work with you to help you manage side effects or to adjust your treatment plan.
