Vitamin A Vitamin A toxicity, initially presenting with irritability, vomiting, loss of appetite and skin changes, has been reported especially in children. In chronic hypervitaminosis, increased intracranial pressure and cirrhosis-like liver syndrome are observed.
Resolution of the symptoms usually occurs upon withdrawal of the vitamin. A daily dose in excess of 150,000 iu or a single intake of more than 1,500,000 iu often leads to toxicity. Vitamin D Vitamin D can also lead to overt toxicity.
Calcium metabolism is disturbed and calcification of soft tissue including the lungs and kidneys results. Cerebral and cardiovascular damage is also observed and infants appear particularly vulnerable. In infants showing increased sensitivity to the vitamin hypercalcaemia is a serious risk.
Adult intakes of more than 50,000 units may lead to poisoning. Symptoms and signs of hypercalcaemia include anorexia, nausea, vomiting, constipation, abdominal pain, muscle weakness, thirst, polyuria, drowsiness, confusion, nephrocalcinosis, renal calculi and in severe cases, cardial arrhythmias, coma and cardiac arrest.
The above effects are generally only likely to occur if doses in excess of those recommended are taken and/or for prolonged periods.
4 Special Warnings And Special Precautions For Use There are serious risks of developing hypercalcaemia when calcium salts or thiazides are co-administered. Serum calcium, phosphate, alkaline phosphatase, liver function tests and magnesium should be monitored when indicated.
Absorption of Vitamin A is reduced in cystic fibrosis, hepatic diseases, pancreatic dysfunction and in patients with intestinal infections. The use of Vitamin A in renal diseases requires extreme caution. Do not exceed the stated dose.
