Check Your Eligibility
TRIKAFTA is for people with CF age 2 years and older with at least one F508del mutation or at least one other mutation that is responsive to TRIKAFTA. Enter your mutations to see if at least one of them is eligible.
Most people with CF have 2 CF mutations, 1 on each copy of the CF gene. However, in rare instances, 1 copy of the CF gene can have more than 1 mutation. This is called a compound, or complex, mutation.
To enter 2 or more mutations into 1 entry field, separate them with a semicolon, space, comma, or forward slash. For example, if your mutations are R74W/V201M/D1270N and W1282R, use the Mutation 1 field to enter: R74W; V201M; D1270N and the Mutation 2 field to enter: W1282R.
If you don’t know your or your loved one's CF gene mutations, it’s important to work with your healthcare provider to identify them. Knowing your mutations can help determine if TRIKAFTA could be right for you.
Based on the information entered, you may be eligible for TRIKAFTA.
Talk with your healthcare provider to see if TRIKAFTA is right for you.
Neither CF gene mutation you entered is eligible for TRIKAFTA.
Talk with your healthcare provider to discuss your CF care plan and treatment options that may be right for you.
We’re sorry, we do not recognize 1 or both of the mutations you entered.
Talk with your healthcare provider to discuss your CF care plan and treatment options that may be right for you.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. The dose of TRIKAFTA may need to be adjusted when taken with certain medicines.
TRIKAFTA may affect the way other medicines work, and other medicines may affect how TRIKAFTA works. The dose of TRIKAFTA may need to be adjusted when taken with certain medicines. Ask your doctor or pharmacist for a list of these medicines if you are not sure.
Especially tell your doctor if you take:
- antibiotics such as rifampin (RIFAMATE®, RIFATER®) or rifabutin (MYCOBUTIN®)
- seizure medicines such as phenobarbital, carbamazepine (TEGRETOL®, CARBATROL®, EQUETRO®), or phenytoin (DILANTIN®, PHENYTEK®)
- St. John’s wort
- antifungal medicines including ketoconazole, itraconazole (such as SPORANOX®), posaconazole (such as NOXAFIL®), voriconazole (such as VFEND®), or fluconazole (such as DIFLUCAN®)
- antibiotics including telithromycin, clarithromycin (such as BIAXIN®), or erythromycin (such as ERY-TAB®)
Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.
What should I avoid while taking TRIKAFTA?
- Avoid food or drink that contains grapefruit while you are taking TRIKAFTA
What are the possible side effects of TRIKAFTA?
TRIKAFTA can cause serious side effects, including:
- Liver damage and worsening of liver function in people with severe liver disease that can be serious and may require transplantation. Liver damage has also happened in people without liver disease
- High liver enzymes in the blood, which is a common side effect in people treated with TRIKAFTA. These can be serious and may be a sign of liver injury. Your doctor will do blood tests to check your liver:
- before you start TRIKAFTA
- every 3 months during your first year of taking TRIKAFTA
- every year while you are taking TRIKAFTA
Your doctor may do blood tests to check the liver more often if you have had high liver enzymes in your blood in the past.
Call your doctor right away if you have any of the following symptoms of liver problems:
- pain or discomfort in the upper right stomach (abdominal) area
- yellowing of your skin or the white part of your eyes
- loss of appetite
- nausea or vomiting
- dark, amber-colored urine
- Abnormality of the eye lens (cataract) has happened in some children and adolescents treated with TRIKAFTA. If you are a child or adolescent, your doctor should perform eye examinations before and during treatment with TRIKAFTA to look for cataracts
The most common side effects of TRIKAFTA include:
- headache
- upper respiratory tract infection (common cold) including stuffy and runny nose
- stomach (abdominal) pain
- diarrhea
- rash
- increase in liver enzymes
- increase in a certain blood enzyme called creatine phosphokinase
- flu (influenza)
- inflamed sinuses
- increase in blood bilirubin
Tell your doctor if you have any side effect that bothers you or that does not go away. These are not all the possible side effects of TRIKAFTA. For more information, ask your doctor or pharmacist. Call your doctor for medical advice about side effects. You are encouraged to report side effects to FDA at 1-800-FDA-1088.
