wie lange vor allergietest kein cetirizin — what symptoms are typical?

The question addresses two aspects: the recommended washout period for cetirizine before an allergy test and typical allergy symptoms. For skin prick testing, antihistamines like cetirizine should generally be stopped 3–7 days beforehand, as they can suppress histamine responses and cause false-negative results. The exact duration should be discussed with a physician, as it depends on the drug's half-life and the test type. Typical allergy symptoms include sneezing, runny nose, itchy/watery eyes (hay fever), hives, and in food allergies, gastrointestinal issues or anaphylaxis in severe cases. Evidence comes from clinical guidelines (e.g., from allergy societies). Caveat: Washout periods vary by antihistamine; always consult a doctor. The provided context lacks specific information on cetirizine or allergy symptoms, so this answer is based on general medical knowledge.
