What does Hazelnut interact with?
Certain medications and conditions can influence the outcome of hazelnut allergen testing or increase risk of adverse events.
Avoid: - Beta‑blockers, which may worsen anaphylaxis management. - ACE inhibitors that can potentiate angioedema. - Recent systemic corticosteroid therapy that may suppress skin reactivity.
