What each component does
Fursultiamine hydrochloride, 5.46 mg/mL
Fursultiamine is thiamine tetrahydrofurfuryl disulfide. It is converted to thiamine in the body. Thiamine acts as a coenzyme that the body needs to turn carbohydrates into usable energy, and a lack of it can affect the nerves and the heart. The amount in each ampoule is printed on the carton and package insert.

Handling and preparation
General handling points for trained professionals. The package insert and your prescriber’s instructions take precedence over this page, and we do not give dosing advice.
Step by step
-
Check the product
Confirm the name, strength, lot number and expiry on the carton and ampoule. Do not use if the solution is cloudy or contains particles.
-
Review the patient
Check for hypersensitivity, current medicines and the reason for treatment, such as diet, absorption or increased demand.
-
Open carefully
Open the ampoule in a way that avoids glass fragments entering the solution. Use aseptic technique.
-
Administer as prescribed
Give by the route and at the dose the package insert and prescriber direct. A qualified professional should administer it.
-
Discard the remainder
Single use. Discard any unused solution and the ampoule as clinical waste in line with local rules.
Administration notes
Use only as directed. Dose, interval and route come from the package insert and the prescriber, not from this page.
- Reassess the diagnosis if there is no improvement after about a month. A true vitamin B1 deficiency or another metabolic problem should be confirmed rather than continuing without a clear response.
- Do not use in patients with known hypersensitivity to any component.
- Thiamine injections can rarely cause allergic reactions, so have means to manage them available.
- Single use only. Do not reuse.
