Sodium Thiosulfate
About Sodium Thiosulfate
Sodium Thiosulfate is a sterile injection used in medical emergencies to treat life-threatening cyanide poisoning. It is also prescribed to protect children from severe, permanent hearing loss that can occur during cisplatin chemotherapy. This specialised injection plays a vital role in clinical care by neutralising harmful toxic substances in the body.
Because Sodium Thiosulfate is given as an intravenous injection by healthcare professionals, the timing and frequency of your doses will depend entirely on your specific medical condition and treatment plan. It is injected slowly into a vein during or after your main medical treatment. Drinking plenty of fluids after your treatment is a simple lifestyle measure that can help your body process and clear the medication more effectively.
Most people tolerate this injection well, but some may experience mild side effects like nausea, vomiting, or a temporary headache. If you experience serious side effects, such as severe muscle cramping, rapid breathing, or signs of an allergic reaction, notify your clinical team immediately so they can evaluate your symptoms.
Talk to your doctor before starting this medicine if you have a history of heart failure, high blood pressure, fluid retention, or kidney disease. Do not take this if you are highly sensitive or allergic to any of the ingredients in the injection.
Inform your healthcare provider about all other medications you are taking, as certain intravenous drugs can interfere with how this injection works. It is also best to avoid alcohol during treatment to prevent worsening dizziness. If you are pregnant, breastfeeding, or are an elderly individual, consult your doctor to discuss the safety of receiving this injection.
Uses of Sodium Thiosulfate
Medicinal Benefits
Sodium Thiosulfate provides different clinical benefits depending on the condition being treated, ranging from emergency antidote action to protection against treatment-related complications:
- Rapid Antidote Action: In cyanide poisoning, it provides a source of sulphur that helps the body convert cyanide into the less toxic compound thiocyanate, supporting its elimination.
- Hearing Protection: In children receiving cisplatin chemotherapy, Sodium Thiosulfate can reduce the risk of treatment-related hearing loss when used at the appropriate time and under specialist supervision.
- Support in Calciphylaxis: In selected patients with calciphylaxis, it may help reduce calcium deposits and associated pain, although its effectiveness can vary and its use is generally specialist-directed.
- Supports Recovery: By addressing the underlying toxic or calcium-related process in these specific conditions, Sodium Thiosulfate can support stabilisation, symptom management, and recovery as part of comprehensive medical treatment.
Directions for Use

Patients Concern
Disease/Condition Glossary
Cyanide poisoning: Cyanide poisoning occurs when cyanide enters the body and prevents cells from using oxygen, leading to cell damage and death. It can result from ingestion, inhalation, or skin exposure to cyanide-containing substances. The symptoms of cyanide poisoning include confusion, headache, difficulty breathing, and, in severe cases, seizures or cardiac arrest. Immediate medical treatment is crucial to prevent life-threatening complications.
FAQs
Sodium Thiosulfate belongs to the group of medications called antidotes. It is used in the treatment of cyanide poisoning.
Sodium Thiosulfate is an antidote. Sodium Thiosulfate contains sodium thiosulfate. It works by detoxifying cyanide by providing sulfur, which allows the enzyme rhodanese to convert cyanide into thiocyanate, a less toxic substance excreted in urine. This process reduces cyanide levels in the body, preventing its harmful effects on oxygen use in cells, thus treating cyanide poisoning.
The common side effects of Sodium Thiosulfate include slow blood clotting, low blood pressure, vomiting, headache, disorientation, nausea, salty taste in the mouth, and a warm sensation over the body. Most of these side effects will resolve gradually over time and do not require medical attention. However, consult the doctor if you experience these side effects persistently.
