Iron chelating agent (antidote for iron poisoning)
Deferoxamine mesylate is an iron-chelating agent used to treat iron poisoning and excess iron buildup caused by frequent blood transfusions in patients with chronic anemia. It works by binding to iron in the body so it can be removed. It is not used to treat primary hemochromatosis, as blood removal (phlebotomy) is preferred for that condition.
How it worksDeferoxamine mesylate acts as a chelating agent, meaning it grabs onto excess iron in the bloodstream and tissues so the body can get rid of it.
Brand names:Deferoxamine mesylate
How to take
The dose is based on body weight and the severity of iron overload. For adults, the maximum daily dose is 60 mg/kg/day, and for children, it is 40 mg/kg/day. The minimum dose is 20 mg/kg/day for both adults and children.
The dosage and how it is given must be decided by a healthcare provider based on the specific needs of the patient and the amount of iron in their system.

- ·Long-term use or high doses may damage your hearing or your eyes.
- ·This drug can cause kidney damage; doctors should monitor your kidney function.
- ·High doses given through a vein may cause severe breathing problems.
- ·In children, high doses or low iron levels can cause issues with growth.
Do not use if

- ·Severe kidney disease or inability to urinate (anuia).
Side effects
Common
Serious
- ·Severe allergic reactions (anaphylaxis)
- ·Vision or hearing loss
- ·Kidney failure or kidney disorders
- ·Severe breathing problems (Acute Respiratory Distress Syndrome)
- ·Growth suppression in children
- ·Heart dysfunction (especially if taken with Vitamin C)
- ·Loss of consciousness
Seek help if
- ·Allergic reactions
- ·Changes in vision or hearing
- ·Difficulty breathing
- ·Changes in urination
Interactions
- ·Taking prochlorperazine with deferoxamine mesylate may cause temporary loss of consciousness.
- ·Gallium-67 imaging results may be wrong because the drug causes the body to flush it out through urine very quickly. Stop using the drug 48 hours before this type of imaging.
Special populations
PregnancyThere is no data on how deferoxamine mesylate affects pregnant women. Animal studies showed risks to the mother and the developing fetus. Pregnant women should be aware of these potential risks.
PediatricIt is safe and effective for children 3 years and older with iron poisoning or iron overload from transfusions. It is not recommended for children under 3 unless a doctor sees significant iron movement in their system. Doctors should monitor a child's height and weight every 3 months.
GeriatricThere isn't enough data on people over 65, but reports suggest older adults might have a higher risk of eye problems (like color blindness) and hearing loss. Doctors usually start with a lower dose for elderly patients.
