Polysaccharide iron complex capsules can be used to treat pregnant women with anemia during pregnancy and also for patients who have developed anemia symptoms after delivery. Pregnant women are at high risk of iron-deficiency anemia and can be given iron-rich foods during pregnancy due to malnutrition, as well as medications to supplement iron and correct anemia when necessary. Some of the iron supplements used to treat iron deficiency anemia have gastrointestinal reactions, and this capsule also has mild gastrointestinal reactions, which can be taken after meals to reduce the gastrointestinal reactions.
