Adverse Effects and Precautions

Adverse effects with thiamine are rare, but hypersensitivity reactions have occurred, mainly after parenteral doses. These reactions have ranged in severity from very mild to, very rarely, fatal anaphylactic shock (see Go to Hypersensitivity.).

Breast feeding.

Supplementation did not significantly affect thiamine concentration in breast milk of healthy, well-nourished women when compared with those not given thiamine; the authors supposed that absorptive capacity of the mammary gland may be saturable.1 Based on this, the American Academy of Pediatrics considers its use to be usually compatible with breast feeding.2

The UK CSM had received, between 1970 and July 1988, 90 reports of adverse reactions associated with the use of an injection containing high doses of vitamins B and C. The most frequent reactions were anaphylaxis (41 cases, including 2 fatalities), dyspnoea or bronchospasm (13 cases), and rash or flushing (22 cases); 78 of the reactions occurred during, or shortly after, intravenous injection and the other 12 after intramuscular injection.1 They recommended that parenteral treatment be used only when essential, and that, when given, facilities for treating anaphylaxis should be available. They also recommended that, when the intravenous route was used, the injection be given slowly (over 10 minutes). Various authors2,3 have noted that parenteral treatment is essential for the prophylaxis and treatment of Wernicke's encephalopathy (see Go to Wernicke-Korsakoff syndrome.). However, further reports of anaphylaxis to parenteral thiamine have since been described,4-6 including one with a fatal outcome.4

Small amounts of thiamine are well absorbed from the gastrointestinal tract after oral doses, but the absorption of doses larger than about 5 mg is limited. It is also rapidly absorbed on intramuscular injection. It is widely distributed to most body tissues, and appears in breast milk. Within the cell, thiamine is mostly present as the diphosphate. Thiamine is not stored to any appreciable extent in the body and amounts in excess of the body's requirements are excreted in the urine unchanged or as metabolites.

Human Requirements

Thiamine requirements are directly related to the carbohydrate intake and the metabolic rate. A daily dietary intake of about 0.9 to 1.5 mg of thiamine is recommended for healthy men and about 0.8 to 1.1 mg for healthy women. Cereals, nuts, peas, beans, yeast, and pork are rich sources of thiamine. Some other meats especially liver or kidneys, and also fish, contain significant amounts. Flour and bakery products are often enriched with thiamine. Considerable losses of thiamine may result from cooking processes.

UK and US recommended dietary intake.

In the UK dietary reference values (see Go to Human requirements.) have been published for thiamine1 and similarly in the USA recommended dietary allowances (RDAs) have been set.2 In the UK for adult males and females the reference nutrient intake (RNI) is 0.4 mg per 1000 kcal daily and the estimated average requirement (EAR) is 0.3 mg per 1000 kcal daily. In the USA an RDA of 1.2 mg daily in adult males and 1.1 mg daily in females is recommended.

Uses and Administration

Thiamine is a water-soluble vitamin, although some of its derivatives have greater lipophilicity. It is an essential coenzyme for carbohydrate metabolism in the form of the diphosphate (thiamine pyrophosphate, cocarboxylase). Thiamine deficiency develops when the dietary intake is inadequate; severe deficiency leads to the development of a syndrome known as beri-beri. Chronic 'dry' beri-beri is characterised by peripheral neuropathy, muscle wasting and muscle weakness, and paralysis. Acute 'wet' beri-beri is characterised by cardiac failure and oedema. Wernicke-Korsakoff syndrome (demyelination of the CNS) may develop in severe cases of thiamine deficiency notably in association with chronic alcoholism. Severe thiamine deficiency, characterised by lactic acidosis and neurological deterioration, has been reported within a relatively short time of starting thiamine-free total parenteral nutrition; some deaths have occurred.

Thiamine is used in the treatment and prevention of thiamine deficiency. It is given by mouth, the preferred route, or if necessary by the intramuscular or intravenous routes (but see Hypersensitivity, Go to Hypersensitivity.); intravenous injections should be given slowly over 10 minutes. In the treatment of mild chronic thiamine deficiency usual doses of 10 to 25 mg daily by mouth, in single or divided doses, have been recommended. In severe thiamine deficiency doses of up to 300 mg daily are given, and even higher daily doses may be used in Wernicke-Korsakoff syndrome by the intravenous route.

Thiamine is usually given as either the hydrochloride or nitrate salts although other salts such as the dicamsylate, disulfide, monophosphate (monophosphothiamine) or pyrophosphate (cocarboxylase) may be used.

Other compounds that possess vitamin B1 activity and may be given as alternatives to thiamine include benfotiamine, cycotiamine, octotiamine, prosultiamine, and sulbutiamine. Acetiamine, bisbentiamine, and fursultiamine have also been used.

Diabetic neuropathy.

In a small placebo-controlled study, benfotiamine 100 mg given four times daily by mouth significantly improved neuropathic pain in patients with diabetic polyneuropathy (see Go to Diabetic neuropathy.).1

Wernicke-Korsakoff syndrome.

The Wernicke-Korsakoff syndrome is a manifestation of thiamine deficiency seen particularly in alcoholics, but which may accompany other conditions including starvation or prolonged fasting, or persistent vomiting. It was originally classified as two separate disorders, Wernicke's encephalopathy and Korsakoff's syndrome, but these are now thought to represent aspects of a single pathological process.1,2

Classical Wernicke's symptoms comprise confusion, ataxia, ophthalmoplegia, and nystagmus. Ophthalmoplegia and ataxia may precede the mental symptoms by some days. Hypothermia may be seen, and collapse and sudden death may occur in some patients. The manifestations of Korsakoff's syndrome are short-term memory loss, learning deficits, and confabulation. The conditions are associated with demyelination and glial proliferation, as well as haemorrhagic lesions, mainly in the periventricular regions of the brain; characteristic biochemical abnormalities include raised serum-pyruvate concentration, which has been postulated as a cause of encephalopathy.3

Early recognition and treatment is important, both because of the risk of collapse and sudden death,4 and to prevent irreversible damage to the CNS. Korsakoff symptoms respond less well to treatment than those associated with Wernicke's encephalopathy,5 and may indeed only become evident on treatment.

Treatment is with parenteral thiamine, preferably intravenously, to ensure adequate absorption; any risks of parenteral treatment are considered justifiable.1,2,6,7 Although as little as 2 or 3 mg may be enough to reverse the ocular symptoms, which generally begin to improve in 1 to 6 hours, doses of at least 100 mg should be given initially. (In practice a typical dose is 500 mg given intravenously with other vitamins every 8 hours, for 2 days if symptoms persist, and followed by 100 mg twice daily by mouth, or 250 mg daily intravenously until the patient can take oral thiamine.6,8) The ataxia and acute confusional state may also resolve dramatically although improvement may not be noted for days or months. Even several months after the onset of symptoms, treatment with high doses of thiamine has occasionally resulted in recovery.9 The effects of the syndrome on memory are much harder to reverse. Some 25% of patients make a full, and 50% a partial, recovery.5
