Frequently asked questions
- What does Sodium Thiosulfate treat?
- Sodium Thiosulfate (Sodium Thiosulfate) may be used to treat tinea versicolor, arsenic poisoning, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
- Is there a coupon or discount for Sodium Thiosulfate?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Sodium Thiosulfate. To pay less, Sodium Thiosulfate is already a generic — usually the lowest-cost version — so the main levers are comparing cash prices between pharmacies and using a pharmacy discount-card service. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
- Who makes Sodium Thiosulfate?
- Sodium Thiosulfate is marketed by US Army. You can see US Army's full profile, rating, and other products on pharmaranks.

- Sodium Thiosulfate is a generic medication; its active ingredient is Sodium Thiosulfate. Generics contain the same active ingredient as the brand-name original and are usually lower cost.
- Is Sodium Thiosulfate available over the counter?
- No. Sodium Thiosulfate is a prescription (Rx) medication in the US — you need a prescription from a licensed clinician (in person or via telehealth); it isn't sold over the counter. For some conditions there are OTC alternatives — ask your pharmacist.

What people report to the FDA about Sodium Thiosulfate
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 499 reports naming Sodium Thiosulfate, and the FDA flagged 90% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- calciphylaxis88 reports
- nausea40 reports
- metabolic acidosis32 reports
- vomiting24 reports
- sepsis22 reports
- pruritus17 reports
- calcinosis15 reports
- erythema15 reports
Read these as a signal, not a rate. A report does not mean Sodium Thiosulfate caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.
