What would happen if u overdose on iron pills?
Frequently taking iron supplements that contain more than 20 mg of elemental iron at a time can cause nausea, vomiting, and stomach pain, especially if the supplement is not taken with food. In severe cases, iron overdoses can lead to organ failure, internal bleeding, coma, seizure, and even death.
How does iron cause metabolic acidosis?
Hypoperfusion due to significant volume loss, vasodilatation, and negative inotropic effect of iron will result in lactic acidosis. Inhibition of oxidative phosphorylation will promote anaerobic metabolism.
What is the antidote for deferoxamine?

Is 300 mg of iron too much?
For treatment of anemia, the recommended dose expressed as ferrous sulfate is 300 mg every 12 hours and may be increased to 300 mg every 6 hours (regular tablets) or 250 mg daily or every 12 hours (extended release tablets). The dose for preventing iron deficiency anemia is 300 mg once daily of ferrous sulfate.
How many iron pills is too much?
At high doses, iron is toxic. For adults and children ages 14 and up, the upper limit — the highest dose that can be taken safely — is 45 mg a day. Children under age 14 should not take more than 40 mg a day.
Does iron cause anion gap metabolic acidosis?
Metabolic acidosis with an elevated anion gap is typically present in patients with severe iron toxicity. In absence of serum iron concentrations the presence of anion gap metabolic acidosis may be the best predictor of toxicity.
Why deferoxamine is used at iron poisoning?
The provision of deferoxamine was found to not only prevent the oxidative toxicity of iron but to reverse iron-induced tissue damage (Link et al., 1989).
Why deferoxamine is used in iron poisoning?
Desferal can promote iron excretion in patients with secondary iron overload from multiple transfusions (as may occur in the treatment of some chronic anemias, including thalassemia). Long-term therapy with Desferal slows accumulation of hepatic iron and retards or eliminates progression of hepatic fibrosis.
What is the maximum amount of iron per day?

What are the side effects of iron deficiency anemia?
Ingested iron can cause direct caustic injury to the gastrointestinal mucosa, resulting in nausea, vomiting, abdominal pain, and diarrhea. Significant fluid and blood loss can lead to hypovolemia.
What is deferoxamine used for?
Deferoxamine is a medication used in Iron and aluminum toxicity. It is in the chelator class of drugs. This activity reviews the indications, mechanism of action, and contraindications for deferoxamine as a chelator in the management of patients with acute or chronic iron toxicity and discusses the off-label use in aluminum toxicity.
How is the diagnosis of iron toxicity determined?
The diagnosis of iron toxicity is based on the history and clinical presentation. Serum iron levels are used to determine a patient’s potential for toxicity. A serum iron level measured at its peak, 4 to 6 hours after ingestion, is the most useful laboratory test.
