Parkitinib may cause side effects such as diarrhea, nausea, and fatigue, which need to be alleviated through dietary adjustments, medication interventions, and lifestyle management. The following are specific response measures:

Diarrhea management

Maintain sufficient water intake and avoid dehydration. You can drink oral rehydration salts or light soup containing electrolytes. Reduce intake of high fiber, high-fat, and dairy products, and choose easily digestible foods such as bananas and rice. If diarrhea persists or worsens, doctors may recommend antidiarrheal drugs such as loperamide, which should be used according to medical advice.

2 Nausea control

Eat in small portions and avoid taking medication on an empty stomach. Choose dry foods such as bread and cookies, and avoid greasy or strongly scented foods. The doctor may prescribe antiemetic drugs such as ondansetron. If vomiting occurs after taking the medication, there is no need to take the next dose as planned.

3 Fatigue Relief

Reasonably arrange activities and rest time to avoid overexertion. Mild exercise such as walking may improve physical fitness. If accompanied by anemia symptoms (pale, dizziness), seek medical attention promptly to check hemoglobin levels. Severe fatigue needs to be evaluated for its association with thyroid dysfunction.

4 Comprehensive precautions

Record the frequency and severity of symptoms, and provide detailed feedback to the doctor during follow-up visits. Avoid taking other antidiarrheal/antiemetic medications on your own and consult a doctor first. If severe symptoms such as bloody stools, persistent vomiting, or extreme weakness occur, seek medical attention immediately.
