How long does it take for the side effects of Larotinib (Vitaika) to disappear on their own and how to deal with them?

Larotrectinib is a targeted drug targeting NTRK gene fusion-positive solid tumors and is generally well tolerated in clinical treatment. The side effects of most patients are mild to moderate, such as fatigue, dizziness, nausea, vomiting, constipation, increased liver function indicators, etc. These adverse reactions are often more obvious in the early stages of medication. As the body gradually adapts to the medication, some symptoms may resolve on their own within a few days to two weeks.

For transient discomfort, such as mild dizziness or fatigue, patients usually only need to pay attention to rest and ensure adequate sleep, and do not need to worry too much. In most cases, these side effects do not prevent continued treatment and do not require additional pharmacological intervention. If it is accompanied by mild gastrointestinal reactions, the discomfort can be alleviated by eating divided meals and avoiding greasy and irritating foods.

However, if the patient experiences persistent liver function abnormalities (such as elevated transaminases), obvious gastrointestinal symptoms, or side effects that affect daily life, he or she needs to communicate with the doctor in time. The doctor may recommend a brief discontinuation of the medication, a dose adjustment, or additional symptomatic treatment to help the patient better tolerate the medication. Most side effects usually disappear within 1 to 2 weeks after stopping the drug or adjusting the dose.

In general, most of the side effects associated with larotrectinib are mild to moderate, and often reduce or subside on their own within a period of time after taking the drug. Patients should maintain regular follow-up visits during treatment, and regularly monitor hematological indicators and liver and kidney functions. If the symptoms are mild, you can observe them first; if the symptoms worsen or persist, you need to follow the doctor's advice and adjust the medication plan to ensure the safety and effectiveness of the treatment.
