Zyrtec and pregnancy: what we know
Pregnancy and breastfeeding are special periods where every medication choice deserves careful review. Zyrtec (Cetirizine) is no exception. The prescribing information for Cetirizine 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 Zyrtec
According to the prescribing information for Cetirizine, the available human data in pregnancy may be limited, supportive, or restrictive depending on the molecule. Some Allergy and Antihistamines 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. Cetirizine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released by mast cells during allergic responses. The prescriber weighs the benefit of breastfeeding, the importance of Zyrtec, and the availability of alternative therapies.
