Administering IV Iron Effective in Pregnant Females with Iron Deficiency Anaemia than Oral Iron Intake: Randomised Trial Finds - Video

A team of researchers in a recently concluded clinical trial, called the IVON TRIAL, tested a medicine for treating anaemia (low blood level), called ferric carboxymaltose. They compared the effectiveness and safety of this medicine with that of a popular tablet, called ferrous sulphate, which is currently being used to treat anaemia in Nigeria. They found that this new medicine given in drip (continuous fluid) through the vein works faster and better than iron tablets taken by mouth for treatment of anaemia; and it is as safe as the tablet.

The study enrolled 1,056 pregnant women, aged 15 – 49 years, who were between five and seven-and-half months pregnant and had anaemia with haemoglobin (red blood level) measurement less than 10 g/dl.

“We used a web-based platform to assign them to treatment groups. Half of the women were treated with one dose of iron given in drip through the vein while half took iron tablets three times a day till they gave birth”, says Ochuwa A. Babah, a doctoral student at Department of Global Public Health, Karolinska Institute and one of the authors of the paper.

Their haemoglobin levels and iron levels were checked, and they were screened for depression at specific time points. They were followed-up until six weeks after delivery to collect more data from mother and baby. Blood was collected from the baby’s cord at delivery to know if the medicine affected the baby’s phosphate level.

Only one dose of iron (ferric carboxymaltose) given by drip through a vein during pregnancy causes a faster rise in blood level after four weeks compared to iron tablet taken by mouth three times every day. The drip iron also corrects low body iron better than iron tablets. The side effects of the drip iron are comparable to that with iron tablets, with no adverse effect on the babies.

“These findings are reassuring because pregnant women often reject new medicines because of fear of harm to their babies. We now have evidence that implementing the use of this new drip iron (ferric carboxymaltose) in regions where many pregnant women suffer anaemia like Africa, will be a valuable step towards reducing the proportion of pregnant women who suffer from this condition and its complications”, says Ochuwa A. Babah and continues:

“The pregnant women were willing to accept the drip iron during pregnancy, supported by their families. The healthcare workers were ready to administer drip iron but identified a need to increase staff strength and possibly medicine subsidy. We know from the clinical trial that the drip iron is effective and safe, so we are already liaising with the Federal Ministry of Health, Nigeria to add it to the essential drug list.”
