was tun bei allergischer reaktion — when to see a doctor?

For an allergic reaction, the approach depends on severity. Mild symptoms like local rash, itching, or sneezing can often be managed with antihistamines (e.g., cetirizine). However, seeing a doctor is advisable to identify the trigger and discuss appropriate treatment. Severe symptoms such as difficulty breathing, swelling of the face or throat, rapid pulse, dizziness, or loss of consciousness indicate a medical emergency (anaphylaxis). In that case, call emergency services (911 in the US, 112 in Europe) immediately and use an epinephrine auto-injector if available. Even after a mild reaction, consult a doctor if symptoms persist or worsen. Important: This text does not replace medical advice. When in doubt, always contact a healthcare professional. Genetic tests like MyBody-X are not relevant for acute allergic reactions but may provide insights into predispositions over the long term.
