This information is intended only for healthcare professionals:
- Infusions with silibinina should be started as soon as possible after poisoning, even without waiting for the diagnosis of mushroom poisoning to be confirmed.
- The recommended dose is 20 mg of silibinina per kg of body weight and day, divided into 4 intravenous infusions of 2 hours each, with a 4-hour interval between them, while controlling fluid balance. In each infusion, 5 mg of silibinina per kg of body weight will be administered. Thus, for the treatment of a 70 kg patient, one vial (350 mg of silibinina) will be needed for each infusion.
- Instructions for reconstitution:
- The contents of the vial are dissolved with a minimum of 35 ml of the infusion solution to be administered (0.9% sodium chloride solution or 5% glucose solution).
- The required amount of reconstituted solution (1 ml = 10 mg silibinina) is added to the rest of the saline or glucose solution, depending on the patient's weight.
- Once reconstituted, the solution is stable for 6 hours at 30°C and 24 hours at 2-8°C.
- The administration of the preparation should be by intravenous infusion over 2 hours.
- After an interval of 4 hours, another infusion of the same duration (2 hours) will be performed, so that in 24 hours, 4 infusions will be carried out. This regimen should be continued until the complete disappearance of symptoms of poisoning.
- Precautions:
- A strict control of the electrolyte and acid-base balance, as well as the fluid balance of patients undergoing treatment with this medicine, must be maintained.
- According to the recommended daily dose of 20 mg of silibinina per kg of body weight and the corresponding amount of saline solution needed for its dissolution, up to approximately 0.39 mmol of sodium per kg of body weight/day will be administered.
- Extracorporeal detoxification measures, such as hemoperfusion or hemodialysis, should be performed during the intervals when the infusion is not being administered, in order to avoid the elimination of silibinina from the bloodstream as much as possible.
- The disposal of unused medicinal products and all materials that have come into contact with them should be carried out in accordance with local regulations.
