\ Yes, a swollen face can indicate an allergic reaction to medications like Calpol (paracetamol) or Sucrafil (sucralfate), though this is uncommon. Mouth ulcers can also sometimes be linked to underlying viral infections or, rarely, medication reactions. To be safe, please stop giving both medications right away and consult your pediatrician for a proper evaluation. If you notice any difficulty breathing, swallowing, or extreme lethargy, please seek emergency medical care immediately.
