Estriol and pregnancy: what we know
Pregnancy and breastfeeding are special periods where every medication choice deserves careful review. Estriol (Estriol) is no exception. The prescribing information for Estriol provides specific guidance, and the right decision depends on the indication, alternatives, gestational stage and the woman's overall medical picture.
Pregnancy safety data for Estriol
According to the prescribing information for Estriol, the available human data in pregnancy may be limited, supportive, or restrictive depending on the molecule. Some Estrogen (weak) agents are routinely used in pregnancy when needed; others are avoided. The risk-benefit calculation includes the importance of treating the underlying condition and the consequences of leaving it untreated.
Breastfeeding considerations
Breastfeeding considerations are usually separate from pregnancy considerations. Some active ingredients pass into breast milk in negligible amounts; others are present at levels that warrant caution. Estriol binds estrogen receptors but with shorter receptor occupancy and weaker activation than estradiol, producing a 'weak' estrogenic effect. The prescriber weighs the benefit of breastfeeding, the importance of Estriol, and the availability of alternative therapies.
