Hi, Thanks for posting in HCM. Dexorange syrup is hematinic syrup with iron, folic acid and vitamin B12 as its ingredients. It rapidly supplements elemental iron so that iron deficiency is quickly controlled. It also provides hemopoietic vitamins and helps to correct anemia faster by replenishment of tissue iron stores. However, it is not have anything to do with increase in appetite. It may not be much of use to gain weight. You can gain weight by having calorie rich foods along with leafy vegetables, pulses, fruits, sprouts and protein rich foods. To increase your hunger, you can use Cyproheptadine containing syrup with or without digestive enzymes, amino acids and vitamin preparations, to improve your appetite. Hope the information provided would be useful. All the best.
