DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


Rare hypersensitivity/allergic reactions have occurred with thiamin supplementation. A small number of life-threatening anaphylactic reactions have been observed with large parenteral (intravenous, intramuscular, subcutaneous) doses of thiamin, generally after multiple doses.

Skin irritation, burning, or itching may rarely occur at injection sites.

Contact dermatitis may occur with occupational exposure and may cause sensitization and lead to dermatitis-type reactions after subsequent oral or injected administrations.

Side Effects and Warnings

Thiamin is generally considered safe and relatively nontoxic, even at high doses. No clear tolerable upper level (UL) of intake has been established. Dermatitis or more serious hypersensitivity reactions occur rarely.

Large doses may cause drowsiness or muscle relaxation.

Injections of thiamin may cause burning. Reactions can often be avoided by slow administration into larger veins.
