1. Preparation and genetic testing confirmation before medication

Tepotinib is suitable for patients with non-small cell lung cancer who have clear METexon14 skipping mutations. Therefore, accurate molecular pathology testing must be performed before use. It is recommended that patients choose qualified medical institutions or laboratories and use proven testing technologies, such as NGS (next generation sequencing), to ensure the accuracy of test results. It is not recommended to use tepotinib blindly in patients without genetic confirmation to avoid delaying the best treatment opportunity.

In addition, before taking medication, doctors need to conduct a comprehensive assessment of the patient's liver, kidney, cardiopulmonary and past medical history, and exclude patients with severe organ dysfunction or severe comorbidities to ensure medication safety.

2. Taking method and dosage adjustment

Tepotinib is an oral preparation. It is recommended to take it once a day. The usual dose is 450mg. It should be taken continuously until disease progression or intolerable side effects occur.

If adverse reactions occur, the doctor may adjust the dose or temporarily discontinue the drug according to the specific situation. Common dose adjustment strategies include reducing the daily dose to 300 mg and discontinuing the drug in the event of severe side effects until symptoms subside before resuming. Patients should never adjust the dosage or stop taking the medicine on their own and should always follow their doctor's advice.

Common adverse reactions of tepotinib include edema (especially edema of the lower limbs), nausea, diarrhea, rash, fatigue, etc. Edema is the most typical and serious side effect. Patients should pay attention to changes in weight and limbs, and notify the doctor in time if obvious edema occurs. For edema, conservative treatment methods such as salt-restricted diet and lower limb elevation can be adopted, and diuretics can be used if necessary.

Diarrhea and nausea can be treated by adjusting your diet, eating small amounts more often, and avoiding greasy and irritating foods. Your doctor may also prescribe antidiarrheal or anti-nausea drugs as an auxiliary treatment. The rash usually manifests as mild erythema or itching. Keep the skin clean and dry, and topical medications can be used to control it if necessary.

If serious adverse reactions occur, such as difficulty breathing, jaundice, severe diarrhea or skin reactions, you should seek medical attention immediately. The doctor will decide whether to suspend or terminate the medication based on the situation.

4. Life guidance and monitoring during medication

While taking Tepotinib, patients should undergo regular medical examinations, including liver and kidney function, blood routine, electrocardiogram and chest imaging evaluation, in order to detect potential problems in time. It is recommended to conduct follow-up visits every 4-6 weeks, and adjust the frequency of examinations according to the patient's specific conditions.

In terms of diet, maintaining a balanced nutrition and avoiding high-salt and high-fat diets can help reduce side effects such as edema. Maintain appropriate physical exercise to promote blood circulation and body metabolism, but avoid overexertion.

In addition, patients should avoid self-administering over-the-counter medications or supplements, especially those that may affect liver metabolism, to avoid drug interactions. All medication information should be promptly communicated to the attending physician.

5. Answers to frequently asked questions from patients

Question: Does tepotinib need to be taken on an empty stomach?

Answer: Tepotinib can be taken with food or on an empty stomach, but it is recommended to take it at a fixed time every day to ensure stable blood concentration.

Question: What should I do if I miss a dose of Tepotinib?

Answer: If the missed dose is short, take it as soon as possible; if it is close to the next dose time, skip the missed dose and take it at the normal time. Never take a double dose at one time.

Q: Does tepotinib affect quality of life?

Q: Can I drink alcohol while taking medication?

Answer: It is recommended to avoid drinking alcohol to reduce the burden on the liver and reduce the risk of adverse reactions.

Tepotinib, as a targeted drug for METexon14 skip mutation non-small cell lung cancer, has significantly improved the treatment prognosis of patients. Rational drug use, strict monitoring and active response to side effects are the keys to ensuring efficacy and safety. Patients and their families should work closely with doctors to master the key points of medication, provide timely feedback on physical conditions, and jointly promote successful treatment and achieve better quality of life.
