PrussianBlue capsules are mainly used for detoxification treatment of radioactive cesium/thallium poisoning, and their side effects involve multiple systems, requiring targeted mitigation measures. The following provides a detailed explanation from three aspects: common adverse reactions, special risks, and response strategies.

1. Common adverse reactions

(1) Gastrointestinal reactions: The incidence of constipation is about 40%. It is recommended to drink more than 2L of water daily and supplement with dietary fiber.

(2) Fecal staining: 100% blue stool appears, which is a normal drug metabolism phenomenon and does not require intervention.

2. Special risk warning

(1) Electrolyte imbalance: may cause hypokalemia, requiring weekly monitoring of blood potassium levels and oral potassium supplementation if necessary.

(2) Allergic reactions: Contains iron cyanide components, and should be closely monitored for allergic symptoms such as rash and difficulty breathing during the initial stage of medication.

3. Targeted mitigation measures

(1) Constipation management: Penetrating laxatives (such as lactulose) can be used in combination, and irritating laxatives should be avoided to prevent intestinal mucosal damage.

(2) Dietary regulation: During treatment, limit high potassium foods (bananas, orange juice, etc.) to avoid affecting the accuracy of electrolyte monitoring.

(3) Medication monitoring: Regular fecal radioactivity testing is required until the excretion radioactivity drops to a safe threshold.
