wie lange vor allergietest cetirizin absetzen — what are common causes?

The question about discontinuing cetirizine before an allergy test is not addressed in the provided MyBody-X contexts. Based on general medical guidelines, cetirizine (and other second-generation antihistamines) should be stopped 3–7 days before a skin prick test, as it can suppress the histamine response. The exact duration depends on the drug's half-life (cetirizine ~8–9 hours, but 3 days is often sufficient). Always consult your doctor for personalized advice. Common causes of allergies include pollen, dust mites, mold, pet dander, and certain foods. The evidence for the discontinuation recommendation is human-strong (guidelines), but the provided context lacks this specific information.
