Generic Name: Deferiprone
Product Name: Ferriprox
Ferriprox tablets contain an ingredient called deferiprone. This is used to treat patients with thalassaemia major, because these patients need to undergo blood transfusion, iron is accumulated in the body over time. If the excess iron is not removed, it can cause serious damage to many organs in the body.
Usually a medication called desferrioxamine is used to treat these patients with iron overload. However, if the patients are unable to take desferrioxamine or this has proven ineffective, deferiprone is used.
Deferiprone binds to the iron in the blood and will be excreted from the body, hence, removing excess iron. Studies have shown that deferiprone can reduce the iron store in the body as well. However, the exact method on how it acts is unknown.
Deferiprone is a prescription-only drug available in the form of tablets.
- Ferriprox comes in the form of tablets, each containing 500mg of deferiprone.
- The dosage of deferiprone is 25mg/kg of body weight 3 times a day, hence, giving a total of 75mg/kg of body weight.
- The dosage should be calculated to the nearest half tablet (i.e. 250mg corresponding to half the tablet). For example an average 70kg person would require 1750mg 3 times a day, equivalent to 3.5 tablets 3 times a day. The total daily dose for this person would be 5250mg.
