Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. By your history and description, possibility of allergy to apricot pits is more likely. So apply Mometasone cream on cheeks. Give her combination of antihistamine (Levocetirizine, Fexofenadine) and anti allergic (Montelukast). Avoid apricots in future. She will be alright with all these in 2-3 days. Hope I have solved your query. I will be happy to help you further. Wishing good health to your wife. Thanks.
