What Are The Side Effects Of Iron Supplements?

Overall Weakness

Although it is uncommon, some patients could experience overall weakness and a general feeling of being unwell after having an iron injection. In these cases, overall weakness occurs in the absence of dizziness or feeling faint. Overall weakness also develops in the later stages of an iron overdose. If weakness is present after receiving an iron injection, the patient should alert the healthcare provider who administered it immediately. For weakness that occurs at home in conjunction with breathing difficulties, heart rate increases, or skin that is clammy or blue, emergency medical attention is required. While waiting for medical attention, the patient should try to sit or lie down to prevent a fall. It can be helpful for doctors at the hospital to know when the patient first started feeling weak and how long this symptom has persisted. The doctor will also need to know about all of the medications the patient is taking and whether any other symptoms are present. Weakness generally resolves quickly with successful treatment.

Dark Stools

Dark stools are a very common side effect of oral iron supplements. The stool may appear dark green or black, and these discolorations are caused by unabsorbed iron. Generally, dark stools associated with the use of oral iron supplements are considered harmless. They may resolve as the patient's body adjusts to the medication, and medical treatment is not normally necessary. If dark stools persist for a prolonged period or if they become bothersome, the patient should mention them to their primary care physician. Black stools accompanied by stomach pain, sharp cramps in the abdominal area, or red streaks in the stool may indicate a potentially serious medical issue. Patients with these symptoms should contact their healthcare provider immediately.
