Effects of this medicine

Vitamin A deficiency causes difficulty seeing in the dark, and desiccation and cornification of skin and mucosa. Vitamin A forms photopigment (rhodopsin), which is needed to see things in the dark, by binding to opsin (erythropigment in the retina). This medicine improves night blindness by supplying vitamin A and dry eye by stimulating mucus secretion of mucosa.
It is usually used in the treatment of night blindness, conjunctival xerosis, corneal xerosis, and keratomalacia attributed to vitamin A deficiency, and hyperkeratotic dermatitis suspected to be due to vitamin A deficiency, and for supplementation of vitamin A when being insufficient intake of vitamin A through food ingestion.
