Drug interactionsContraindicated :
- Cyclines, in case of intake of 10 000 IU/day and more: risk of intracranial hypertension.
- Retinoids: risk of symptoms suggestive of hypervitaminosis A.
Fertility, pregnancy and breastfeeding
Pregnancy:Vitamin A is teratogenic in animals in several species.
In the human species, cases of malformations have been reported with high doses. However, to date, the absence of a reliable epidemiological study and the small number of isolated notifications prevent a definitive conclusion on the reality of this malformative risk.
Consequently, vitamin A at high doses will only be prescribed during pregnancy in case of proven deficiency.
Breastfeeding:
Use is not recommended in case of breastfeeding due to the risk of overdose in the newborn.
Adverse effects
Any adverse effect is likely to be a manifestation of overdose and must lead to discontinuation of treatment.
Reporting of suspected adverse effects:Reporting of suspected adverse effects after authorization of the medicinal product is important. It allows continuous monitoring of the benefit/risk ratio of the medicinal product.

Overdose
- Clinical signs of acute overdose with vitamin A (doses greater than 150 000 IU):
- Digestive disorders, headaches, intracranial hypertension (manifesting in the infant by bulging of the fontanelle), papilledema, psychiatric disorders, irritability, even convulsions, delayed generalized desquamation.
- Clinical signs of chronic overdose with vitamin A (risk of chronic intoxication during prolonged intake of vitamin A at supraphysiological doses in a non-deficient subject):
- Intracranial hypertension, cortical hyperostosis of long bones and early epiphyseal fusion. The diagnosis is generally made on the observation of sensitive or painful subcutaneous swellings at the level of the extremities of the limbs. Radiographs show diaphyseal periosteal thickening at the level of the ulna, fibula, clavicles and ribs.
Pharmacodynamics
Pharmacotherapeutic class: Vitamin A (ATC code: A11CA01 ; A: Digestive system and metabolism).
Vitamin A is a fat-soluble vitamin. It plays an important role in the formation of visual purple (necessary for adaptation of vision when light decreases), in cell multiplication and epithelial and tissue trophicity.
Pharmacokinetics
Digestive absorption of vitamin A at the level of the small intestine is linked to that of fats.
Hepatic storage is important (at 90 %) and occurs mainly in the form of retinyl esters.
Vitamin A is bound to RBPP (retinol-binding plasmatic protein) formed by the liver.
Elimination occurs via the fecal and urinary routes in the form of derivatives.
Storage conditions
- Shelf life
- 2 years.
Store at a temperature not exceeding 25 °C and protected from light.
