Treatment of Acute Urticaria During Pregnancy or Lactation
Acute urticaria during pregnancy or while breastfeeding presents a specific management challenge: treatment must control symptoms effectively while meeting the highest safety standards for both mother and infant.
Clinical Scenario
This protocol addresses acute urticaria in patients who are pregnant or breastfeeding (lactating). The same clinical considerations apply to both groups, though safety requirements are particularly stringent during pregnancy. Not all standard urticaria therapies are appropriate in this context.
Treatment Approach — partial overview
A specific generation of H1-antihistamine is recommended, with certain agents within that class preferred over others given the safety requirements of this population. A different generation of antihistamine is to be avoided. The complete agent selection and full clinical guidance are available in the structured protocol.
Treatment Goal
Complete symptom control — full absence of wheals and pruritus (UAS = 0) — while prioritising the safety and quality of life of mother and infant throughout treatment.

- The same considerations in principle apply to pregnant and lactating women.
- Nevertheless, since the highest safety is mandatory in pregnancy, the suggestion for the use of modern 2nd generation H1-antihistamines is to prefer loratadine with the possible extrapolation to desloratadine and cetirizine with a possible extrapolation to levocetirizine.
- 1st generation H1-antihistamines should be avoided.
- Use of 2nd generation H1-antihistamines is advised, as nursing infants occasionally develop sedation from the old 1st generation H1-antihistamines transmitted in breast milk.
- We recommend aiming at complete symptom control in urticaria, considering as much as possible the safety and the quality of life of each individual patient.
