Feosol Caplets :: SmithKline Beecham Consumer


FEOSOL Caplets contain pure iron micro particles called carbonyl iron. Replacing FEOSOL Capsules, this advanced formula is specially designed to be well absorbed, gentle on the stomach and offers enhanced safety in the event of an accidental overdose. Each FEOSOL carbonyl iron caplet delivers 45 mg of pure elemental iron, the same amount of elemental iron contained in the 225 mg ferrous sulfate capsule. At equivalent doses, carbonyl iron and ferrous sulfate were shown to be equally efficacious in correcting hemoglobin, hematocrit and serum iron levels in iron-deficient patients 1 .


According to the American Association of Poison Control Centers, iron containing supplements are the leading cause of pediatric poisoning deaths for children under six in the United States 2 . Widely used as a food additive, carbonyl iron must be gastrically solubilized before it can be absorbed, giving it lower toxicity and enhancing its safety versus any of the ferrous salts 3 . As a result, carbonyl iron presents less chance of harm from accidental overdose. In addition, at equivalent doses, carbonyl iron side effects are no greater than those experienced with ferrous sulfate 4 .


Do not exceed recommended dosage. The treatment of any anemic condition should be under the advice and supervision of a physician. Since oral iron products interfere with absorption of oral tetracycline antibiotics, these products should not be taken within two hours of each other. Occasional gastrointestinal discomfort (such as nausea) may be minimized by taking with meals. Iron containing medication may occasionally cause constipation or diarrhea.

If you are pregnant or nursing a baby, seek the advice of a health professional before using this product.

WARNING:   Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.
