Side effects of imatinib mesylate tablets include gastrointestinal reactions, hematologic abnormalities, skin and appendage reactions, edema, musculoskeletal pain, etc. Most are mild to moderate in severity and can be relieved with symptomatic management. Close monitoring of physical changes is necessary during treatment. If severe rash, persistent vomiting, or abnormal bleeding occurs, prompt medical attention is advised.
1. Gastrointestinal reactions: Common symptoms include nausea, vomiting, diarrhea, and abdominal pain. These often occur early in treatment and are related to drug irritation of the gastrointestinal mucosa. Tolerance may develop over time. Adjusting the timing of medication intake may help reduce discomfort.
2. Hematologic abnormalities: The drug may cause reductions in white blood cells and platelets, increasing the risk of infection and bleeding. Regular complete blood counts are required during treatment. Dosage adjustments should be made based on laboratory results, and strenuous activities that could lead to injury should be avoided.
3. Skin and appendage reactions: Manifestations include rash, itching, and erythema, mostly mild to moderate in severity. Scratching should be avoided. Mild antiallergic medications may be used under physician guidance. Severe rashes require timely evaluation of continued drug use.
4. Edema: Periorbital and lower limb edema are common and associated with the drug's effect on sodium and water metabolism. Daily salt intake should be controlled, prolonged sitting or standing should be avoided, and moderate activity is recommended to promote circulation. Severe edema requires medical evaluation for cardiac function.
5. Musculoskeletal pain: Muscle aches and joint swelling may occur, usually transient. Symptoms can be alleviated with heat application and light exercise. Overexertion should be avoided. Persistent or worsening pain should be reported to a physician promptly for treatment adjustment.
During treatment, maintain a light and easily digestible diet, follow regular作息 (daily routines), avoid staying up late, pay attention to skin cleanliness and protection, complete routine tests such as complete blood count and liver and kidney function regularly, and take the medication as prescribed in full dose and duration. Do not adjust the dose or discontinue the medication without medical advice.
