welcome to healthcare magic. if your iron levels are low ie u are naemic during pregnancy
you need iv iron if the oral preparation is ineffective or ur unable to tolerate the same. the iv iron given these days is iron sucrose. the dose is calculated as per a simple formula so that your body's requirement is met with. plus some amount is added to build up stores . it is then given in doses on alternate days. you can go in the morning to the hospital get the dose for the day and return by the evening. depending oon your dose u will need to go on alternate days for a couple od days. iron sucrose does not cause any major side effects so u can relax n do not have to be admitted.
