Corticosteroids are potent anti-inflammatory agents. They are considered relatively safe in pregnancy when used in low doses and are designated as category B medications.
What do corticosteroids do in pregnancy?
Corticosteroids are anti-inflammation medicines that help the baby’s lungs mature before being born. They are usually given to women at risk of early labour, typically as two injections, though they can also be given before planned preterm birth and in some cases a repeat course can be given.
When should a pregnant woman take corticosteroids?
A single course of corticosteroids is recommended for pregnant women between 24 0/7 weeks and 33 6/7 weeks of gestation, and may be considered for pregnant women starting at 23 0/7 weeks of gestation, who are at risk of preterm delivery within 7 days 1 11 13.
Can steroids harm an unborn baby?
Steroid injections given to pregnant women before premature birth may increase the child’s risk of later behavioural difficulties, a study has found.
Is it OK to take prednisone while pregnant?
There’s no strong evidence that taking prednisone while pregnant has any harmful side effects. However, some studies connect the use of prednisone and other corticosteroids to complications that can affect the development of a fetus.
What corticosteroids are safe during pregnancy?
Therefore, if steroid treatment is desired for the mother, hydrocortisone, cortisone, or prednisone should be chosen. Dexamethasone and betamethasone cross the placenta with similar maternal and fetal concentrations; thus, they are the treatment of choice for fetal respiratory distress.
Which steroids given in pregnancy?
Three of the most commonly used corticosteroids in pregnancy are prednisolone, dexamethasone and betamethasone (Fig. 2) (Health, 1994).
Who is the good candidate for antenatal corticosteroids?
Antenatal corticosteroid therapy is recommended for women with pre-gestational and gestational diabetes who are at risk of imminent preterm birth. Women who are receiving fetal steroids should have additional insulin according to an agreed protocol and be closely monitored.
Is 37 weeks full term?
At 37 weeks, your pregnancy is considered full-term. The average baby weighs around 3-4kg by now. Your baby is ready to be born, and you’ll be meeting them some time in the next few weeks.
How do corticosteroids mature fetal lungs?
Antenatal steroids that cross the placenta (i.e., synthetic steroids such as dexamethasone or betamethasone) mature the fetal lung, inducing the enzymes for surfactant synthesis and the genes for the surfactant proteins, increase anti-oxidant activity, and reduce oxidative stress.
Do steroids make your baby bigger?
Studies have found that corticosteroid treatment is associated with smaller size at birth. In one large Finnish study, this smaller birth size held true for babies born preterm, near term, or at term.
Which steroids cross the placenta?
Betamethasone and dexamethasone are fluorinated, synthetic corticosteroids with a similar molecular structure and an ability to cross the human placenta from mother to fetus.
What category is prednisone in pregnancy?
US FDA pregnancy category D: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
