Can patients with iron deficiency anemia take potassium chloride?

Iron deficiency anemia should not be treated with potassium chloride; instead, it can be managed by iron supplementation. Before starting iron replacement, serum ferritin and serum iron levels should be measured to monitor treatment response after oral or intravenous iron administration. If gastrointestinal tolerance is good, there is no chronic stomach disease, and no contraindications to iron supplementation, oral iron supplements can be taken. Concurrently, vitamin C or vitamin B complex may also be taken orally to aid in treatment. However, gastrointestinal side effects such as gastric irritation may occur, which some patients cannot tolerate—particularly elderly individuals with poor digestive function, who may experience gastrointestinal discomfort following iron supplementation.
