Sunvozertinib is a targeted therapy drug for lung cancer with specific gene mutations. Key considerations for its use include strict adherence to medical advice, close monitoring for adverse effects, and avoidance of drug-drug interactions. As a prescription medicine, it must be used under the standardized guidance of a physician; do not adjust the dosage or discontinue the drug on your own. Efficacy and safety should also be regularly evaluated in light of the patient’s condition.
I. Medication Compliance
Take the drug as directed by your physician
Sunvozertinib is to be taken orally at a fixed time each day and is generally recommended for empty-stomach administration (e.g., 1 hour before meals or 2 hours after meals). Follow your physician’s specific instructions for usage.
Dosage adjustment
If a dose is missed, take the missed dose if more than a specified interval (e.g., 12 hours) remains before the next scheduled dose; otherwise, skip it and do not take a double dose. In the event of severe adverse effects (e.g., liver injury, bleeding), the physician will determine whether to reduce the dosage or temporarily suspend medication.
II. Adverse Effect Management
Common reactions
Diarrhea and nausea: Eat small, frequent meals, avoid greasy foods, and take antidiarrheal medication if necessary.
Rash or dry skin: Keep the skin clean, use mild emollients, and avoid sun exposure.
Oral ulcers: Use a soft-bristled toothbrush, avoid irritating foods, and rinse the mouth with normal saline.
Severe reactions
Seek immediate medical attention if symptoms such as dyspnea, chest pain, persistent high fever, severe bleeding (e.g., black stools, hematuria) or abnormal liver function (e.g., jaundice) occur.
III. Drug and Dietary Contraindications
Drug interactions
Avoid concomitant use with potent CYP3A4 inhibitors (e.g., clarithromycin) or inducers (e.g., rifampicin), as these may alter drug efficacy or increase toxicity. Patients taking anticoagulants (e.g., warfarin) must have their coagulation function closely monitored.
Dietary precautions
Avoid grapefruit, carambola and alcoholic beverages, as they may interfere with drug metabolism.
IV. Special Populations and Regular Monitoring
Patients with hepatic or renal impairment
Dosage shall be adjusted based on test results, and hepatic and renal function must be rechecked regularly.
Pregnant and lactating women
This drug may pose risks to the fetus; strict contraceptive measures are required during treatment, and the drug is contraindicated during lactation.
Regular rechecks
Examinations include a complete blood count, hepatic and renal function tests, electrocardiogram (ECG) and imaging scans, which are used to assess tumor progression and drug tolerance.
V. Other Notes
Storage conditions
Store the drug at room temperature, protected from light and moisture, and keep it out of the reach of children.
Lifestyle recommendations
Avoid strenuous exercise or trauma during treatment to reduce the risk of bleeding; maintain a balanced diet and supplement with adequate protein and vitamins in moderation.
Important Reminder: For any questions about medication or the appearance of abnormal symptoms, contact your attending physician promptly and do not attempt to manage symptoms on your own. Targeted therapy requires an individualized treatment plan, and patients must actively cooperate with follow-up visits and clinical examinations.
