Taking elemental iron does not usually cause a decrease in platelets.
Vitamin C supplementation is needed along with iron to promote iron absorption. For patients with iron deficiency anemia who have normal platelet counts, iron supplementation itself will not affect platelets, so taking iron will not cause platelet reduction. However, some patients with iron deficiency anemia may have reactive thrombocytosis secondary to iron deficiency, and platelets in these patients will gradually decrease to normal once iron is supplemented.
When the patients have platelet decrease, they should go to the hospital in time for examination and diagnosis, to clarify the cause of the disease as soon as possible, to exclude blood system diseases, viral infections, drugs and other factors, and to take targeted therapeutic measures under the guidance of professional doctors. Avoid the worsening of symptoms and the negative impact on the patient’s health.
