Why is this medication prescribed?

Trikafta is a medication primarily prescribed for the treatment of cystic fibrosis (CF) in patients aged 12 years and older who have at least one copy of the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which is the most common mutation in people with CF. CF is a genetic disorder that affects the lungs, digestive system, and other organs, leading to the production of thick, sticky mucus that can cause serious respiratory and digestive problems.

Trikafta is a combination drug containing three different medications: elexacaftor, tezacaftor, and ivacaftor. These drugs work together to help improve the function of the CFTR protein, which is defective in people with CF. By improving CFTR function, Trikafta helps reduce the production of thick mucus and improve lung function, thereby reducing respiratory symptoms and the risk of respiratory infections.

How should this medicine be used?

Trikafta is typically taken orally as tablets. Here are the general guidelines for how it should be used:

• Dosage: The usual dosage of Trikafta is one tablet taken orally once daily.
• Administration: Trikafta should be taken with fat-containing food, such as a meal or a snack. This helps with the absorption of the medication into the bloodstream.
• Swallowing: The tablets should be swallowed whole and should not be crushed, chewed, or split.
• Consistency: It’s important to take Trikafta consistently every day, at around the same time each day, to maintain stable levels of the medication in the body and ensure its effectiveness.
• Follow Doctor’s Instructions: Always follow the prescribing doctor’s instructions regarding dosage and administration. They may tailor the dosage or provide specific instructions based on individual factors such as age, weight, and the severity of the condition.
• Monitoring: Regular check-ups with healthcare professionals are important while taking Trikafta to monitor its effectiveness and any potential side effects.
• Other Medications: Inform your doctor about any other medications, supplements, or treatments you are taking, as they may interact with Trikafta.
• Storage: Store Trikafta tablets at room temperature away from moisture and heat. Keep the medication in its original packaging until ready to use.
• Missed Dose: If a dose of Trikafta is missed, it should be taken as soon as possible, unless it is close to the time of the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule resumed. Double doses should not be taken to make up for a missed dose.
• Side Effects: Be aware of potential side effects of Trikafta and report any unusual or severe symptoms to your healthcare provider promptly.

As with any medication, it’s important to use Trikafta exactly as prescribed by the doctor to ensure its safety and effectiveness in managing cystic fibrosis.

Other uses for this medicine

Trikafta is specifically approved for the treatment of cystic fibrosis (CF) in patients aged 12 years and older who have at least one copy of the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. It is not approved for other uses. However, it’s important to note that researchers are continually studying potential applications of medications for various conditions, so future uses of Trikafta or similar medications may emerge as research progresses.

What special precautions should I follow?

Regarding special precautions for Trikafta, here are some important points to consider:

• Genetic Testing: Trikafta is indicated for individuals with specific genetic mutations associated with cystic fibrosis. Genetic testing is typically done to determine if a person has the F508del mutation or other qualifying mutations before prescribing Trikafta.
• Pregnancy and Breastfeeding: The safety of Trikafta during pregnancy and breastfeeding has not been established. If you are pregnant, planning to become pregnant, or breastfeeding, it’s essential to discuss the risks and benefits of taking Trikafta with your healthcare provider.
• Liver Function: Trikafta can affect liver function, so regular monitoring of liver function tests may be recommended during treatment. Inform your doctor if you have a history of liver problems or if you experience symptoms such as yellowing of the skin or eyes (jaundice), dark urine, or abdominal pain.
• Drug Interactions: Trikafta may interact with other medications, including certain antibiotics, antifungal drugs, and medications that are metabolized by the CYP3A enzyme system. Inform your doctor about all medications, supplements, and herbal products you are taking to avoid potential interactions.
• Respiratory Symptoms: While Trikafta can improve lung function and reduce respiratory symptoms in people with cystic fibrosis, it may not be suitable for individuals with certain respiratory conditions or complications. Your doctor will assess your respiratory health before prescribing Trikafta.
• Adverse Reactions: Be aware of potential side effects of Trikafta, such as headache, nausea, sinus congestion, abdominal pain, diarrhea, and rash. Report any unusual or severe symptoms to your healthcare provider promptly.
• Children and Adolescents: Trikafta is approved for use in patients aged 12 years and older. Its safety and effectiveness in younger children have not been established.
• Compliance: It’s important to take Trikafta consistently as prescribed by your doctor to maintain stable levels of the medication in the body and ensure its effectiveness.

Always follow your healthcare provider’s instructions and guidelines for using Trikafta, and discuss any concerns or questions you may have about its use and potential risks.

What special dietary instructions should I follow?

• Fat-containing Food: Trikafta should be taken with fat-containing food, such as a meal or snack, to enhance absorption. This helps ensure that the medication is effectively absorbed into the bloodstream.

• Take it as soon as you remember: If you miss a dose of Trikafta, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for the missed one.
• Continue with regular dosing: It’s important to continue taking Trikafta as prescribed by your doctor, even if you missed a dose. Consistency in taking the medication is crucial for maintaining stable levels in the body and optimizing its effectiveness.
• Notify your doctor: If you frequently forget doses of Trikafta or have difficulty adhering to the prescribed schedule, discuss this with your doctor. They may provide additional guidance or strategies to help you stay on track with your medication regimen.
