Hello, Welcome to HCM. I understand your concern. Daktozin contains Miconazole and zinc oxide. Miconazle is anti-fugal agent. Both these drugs are also used in form of oral gels and not very toxic if ingested in small quantities. If your child has not developed any kind of allergic reaction or not showing any symptoms of toxicity than it is not necessary to consult doctor. If you observe any unusual symptoms like difficulty in breathing, swelling anywhere in body, any sign of irritation in mouth than you should consult doctor. Otherwise there is nothing to worry. Hope this will be helpful. Do ask if any further question is there. Take care.
