Hello and thank you for your question on the forum. Savlon can have side effects associated with it which include skin irritation and rash. It is considered somewhat rare but you may be one of the 'lucky' ones. https://www.drugs.com/uk/savlon-antiseptic-cream-leaflet.html If it was the liquid version, this can cause something like a chemical burn. If your symptoms persist, we recommend seeing your doctor for guidance.
