It is used for the prevention and treatment of vitamin A and D deficiencies, such as rickets and night blindness and pediatric hand and foot convulsions. Vitamin AD drops on the market are available in two sizes for children up to 1 year of age and for children over 1 year of age. Babies can take Iconocin from 15 days of life until they are about two weeks old. Vitamins A and D are essential for human growth and development, especially for the development of fetuses, infants and children, the integrity of epithelial tissues, vision, reproductive organs, the constancy of blood calcium and phosphorus, and the growth and development of bones and teeth. It is important to note that babies must take the recommended dose and not overdose. Children should consult their physician or pharmacist for doses. Children must use Icocin under adult supervision. If a child overdoses or has a serious adverse reaction, he or she should seek immediate medical attention. Do not combine Iconocin with injectable calcium preparations or magnesium oxide or magnesium sulfate to avoid hypomagnesemia and hypercalcemia. Antacids (e.g. aluminum hydroxide) can affect the absorption of vitamin A in this product, so Icocin should not be taken together with antacids. Ecocin is an over-the-counter (OTC) drug and can be purchased and used on its own.
