Dosage and administration
Timing of administration in relation to cisplatin
The timing of sodium thiosulfate administration in relation to cisplatin chemotherapy is critical.
If sodium thiosulfate is administered:
- less than 6 hours after the end of cisplatin infusion: it may reduce the effectiveness of cisplatin against the tumor
- more than 6 hours after the end of cisplatin infusion: it may not be effective in preventing ototoxicity.
Use sodium thiosulfate only after a cisplatin infusion that has lasted 6 hours or less. Do not use sodium thiosulfate if:
- the cisplatin infusion lasts more than 6 hours or
- a subsequent cisplatin infusion is planned within the next 6 hours.
When cisplatin is administered on consecutive days, ensure a minimum interval of 6 hours between the sodium thiosulfate infusion and the next cisplatin infusion.
After the end of the cisplatin infusion:
- Administer a highly effective intravenous multi-agent antiemetic 30 minutes before sodium thiosulfate administration, i.e., 5.5 hours after the end of cisplatin infusion
- This medicine is a ready-to-use solution for infusion
- Prepare the necessary ml of sodium thiosulfate, 80 mg/ml, in a syringe or add it to an empty sterile infusion bag
- Stop the cisplatin hydration fluid and flush the line with 0.9% sodium chloride
- Infuse sodium thiosulfate over 15 minutes (6 hours after the end of cisplatin infusion)
- Flush the line with 0.9% sodium chloride and resume cisplatin hydration immediately after.
Refer to the section "Timing of administration in relation to cisplatin" for crucial information on the timing of sodium thiosulfate administration.
This medicine is presented in a single-use vial containing 8 g in a concentration of 80 mg/ml. The recommended dose of sodium thiosulfate for the prevention of cisplatin-induced ototoxicity is based on body weight and normalized according to body surface area as shown in the following table:
Body weight | Dose | Volume |
>10 kg | 12.8 g/m2 | 160 ml/m2 |
5 to 10 kg | 9.6 g/m2 | 120 ml/m2 |
<5 kg< p> | 6.4 g/m2 | 80 ml/m2 |
