Uses

Thiamine injections are indicated for conditions related to severe vitamin B1 deficiency, which can affect the nervous system, heart, and brain. 

• Treating deficiency diseases: Thiamine injection is used for conditions like beriberi and Wernicke-Korsakoff syndrome, which are caused by prolonged thiamine deficiency.

• Malabsorption issues: It is for patients with thiamine deficiency who cannot take oral supplements due to severe anorexia, nausea, or vomiting.

• Alcoholism-related deficiency: Thiamine deficiency is common in people with chronic alcoholism, and injections are used to replenish vitamin B1 levels.

• Infantile beriberi: It can be used for rapid thiamine restoration in infants with this condition, particularly during acute collapse.

• Other conditions: The injection may be used in cases of pregnancy with severe vomiting, or before giving intravenous dextrose to patients with borderline thiamine status to prevent heart failure.
