Treatment of iron poisoning includes:
- If the symptoms of iron poisoning disappear within a few hours, then there is no need for treatment.
- However, for persistent symptoms without any relief, intervention is needed.
- Immediate treatment includes a gastric wash, which means complete emptying of the stomach using a chemical agent.

How does iron cause toxicity?
Iron causes toxicity thru several mechanisms, including 3: Engages in redox reactions with the formation of free radicals and oxidative damage. Alters cellular energy and metabolism. Uncouples oxidative phosphorylation. Ultimately results in cellular death.
How is iron toxicity determined?
Iron toxicity is determined by the amount of elemental iron (Fe) ingested. Examples of Fe formulations and the amount of elemental Fe contained in each formulation are listed in the table below (adapted from 1 ).
What is Ferrioxamine?
Ferrioxamine is a brick-orange color (AKA vin rose). Two antiquated recommendations guiding the administration of DFO relate to visualizing vin rose in the urine. The first is to administer a DFO challenge (IM shot); if vin rose is present in urine, then continue with further DFO treatment. The second is to continue DFO until vin rose in the urine clears. Both practices have been abandoned secondary to lack of reliability. 1,4
How does the body regulate Fe?
Humans do not synthesize or secrete Fe. Total body Fe is regulated via absorption from the gastrointestinal tract. Absorption occurs in the duodenum, where Fe is stored as ferritin in the intestinal cells. It is then disposed of via epithelial cell shedding or, depending on the body’s need, can be released to transferrin, a serum Fe-binding protein. In Fe overdoses, the corrosive effects of Fe on the GI tract mucosa permit passive absorption of Fe. Once transferrin is saturated, “free” Fe is available to cause toxicity. Iron causes toxicity thru several mechanisms, including 3:
How long does it take for iron to become toxic?
Serious iron toxicity typically occurs within six hours after taking the overdose. Symptoms of iron poisoning vary in progression, depending on the individual and amount of iron ingested. Overall, the symptoms most often occur in five stages. The late-stage symptoms develop only when Stage 1 symptoms are moderate or severe.
What happens if you take iron?
Iron Toxicity and Dosages. If you take in more iron than you need, the excess amount is stored in tissues throughout your body. With a gradual accumulation in the organs, including your pancreas, pituitary gland, heart and liver, complications can occur.
How much iron is in a kilo?
Amounts of 20 to 60 milligrams per kilogram of elemental iron results in moderate symptoms; more than 60 milligrams per kilogram can result in severe toxicity and lead to disease and death, according to a study published in StatPearls in 2019.
Why is iron overloaded?
An intake of too much iron can be accidental, caused from excessive use of iron supplements or can develop from a chronic disorder that prevents the efficient formation of red blood cells. An inherited condition called hemochromatosis can result in the buildup of toxic levels of iron.
What is the most common form of iron?
The most common forms are ferrous sulfate with 20 percent elemental iron, ferrous gluconate with 12 percent elemental iron and ferrous fumarate with 33 percent elemental iron. As well as iron-only types, most multivitamin and mineral supplements, as well as prenatal supplements, often contain iron.

Those with symptoms are admitted to hospital and may require IV fluids (ward, HDU, ICU depending on severity; ideally a paediatric center) Patients with the potential for systemic toxicity may be best managed at larger hospitals where iron levels can be measured and iron chelation therapy administered if needed.
Calculating Amount of Elemental Fe Ingested
Pharmacology and Toxicology
Iron Toxicity: Presentation
- Classically, five stages of iron toxicity are described (adapted from 4): The lack of vomiting early after an ingestion (during stage I) has important clinical significance. If no vomiting has occurred within 6 hours after ingestion, then the patient likely did not ingest a toxic dose. This patient can be medically cleared.2
Laboratory Testing
- For most preparations, a peak Fe level occurs 2–6 hours post-ingestion. The peak level predicts severity of iron toxicity and guides management decisions (see table below). After 6 hours, Fe distributes out of the intravascular compartment, and levels are less useful for predicting toxicity.1Additional lab tests to consider obtaining include: 1. Basic metabolic panel 2. Lactate 3…
Initial Treatment
- The treatment of Fe overdose starts with attention to supportive care and adequate fluid resuscitation. 1. Isotonic fluids: Numerous reasons account for hypovolemia and poor perfusion. Start fluid resuscitation with isotonic fluid boluses to restore hypovolemia. 2. Activated charcoal (or other oral complexing agents): This is INEFFECTIVE at binding...
