What Are The Side Effects Of Iron Supplements?

Increased Heartbeat

The overuse of and allergic reactions to iron supplements could both lead to an increased heartbeat. Excessive iron in the blood is associated with an increased risk of heart rhythm abnormalities too. While oral iron supplements are not typically associated with an increased heartbeat, this side effect is relatively common when iron is given via an injection. For adults, a normal heart rate is between sixty to one hundred beats per minute. Heart rate can be affected by anxiety, medication use, physical activity, caffeine intake, and dehydration. Individuals who receive iron injections should let their nurse or other healthcare provider know immediately if they notice an increased heart rate.

Patients taking oral iron supplements can check their heart rate at home, and this can be done manually or with at-home blood pressure monitors or fitness trackers. Heart rate changes throughout the day, so it may be beneficial for the patient to check their pulse in the morning, afternoon, and evening. Measurements can be recorded in a log and compared over several days or weeks. Individuals who notice their heart rate is consistently above eighty-five beats per minute may want to discuss this with their physician. Prescription medications such as beta-blockers can be used to reduce heart rate if necessary, and doctors might recommend lifestyle modifications, breathing exercises, and stress-reduction techniques as well. Patients who feel a pounding or racing heartbeat, chest pain, or a sensation of skipped or irregular heartbeats should seek urgent medical attention.

Pale and Clammy Skin

Patients in the late stages of an iron overdose may notice pale and clammy skin. Clammy skin generally feels wet, moist, or sweaty. The skin often becomes significantly paler than usual, and this symptom could occur suddenly. Patients with pale and clammy skin might have lips and fingernails that appear blue, and the palms of the hands take on a blue discoloration as well. Patients who have pale and clammy skin along with weakness, unusual tiredness, and shallow and rapid breathing should be taken to an emergency room for immediate evaluation. These patients may develop a weak and fast heartbeat, and seizures could occur. Doctors will make a note of the patient's skin symptoms, and blood tests will be performed to determine the underlying cause. Most patient's skin returns to its normal color once the iron overdose is corrected.
