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. Vitamin A plays an important role in promoting visual development, bone development, preventing anemia and improving immune function. Vitamin D is an important substance that can help your baby absorb calcium and is important for the development of bones and teeth. The synergistic effect of vitamin A and vitamin D can make your baby grow taller and have more comprehensive nutrient absorption. It is important to note that babies must take the recommended dose and not overdose. Children should consult their physician or pharmacist for dosage. Children must be supervised by adults when using Icocin. If a child overdoses or has a serious adverse reaction, he/she should seek medical attention immediately. 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.
