My child is 1 year and 10 months old and accidentally ingested potassium permanganate. The child did not swallow it, and there have been no reactions so far. Previously, I induced vomiting and gave them water, milk, and egg whites. Based on your clinical description of the baby, if it was not swallowed, avoid causing damage to the oral mucosa. The first thing to do if a baby accidentally takes this medication is to repeatedly clean the mouth. Because this medication can erode the mucosa of the digestive system. Therefore, it is best to repeatedly clean the baby’s mouth with warm water. And feed the baby milk and other foods to protect the gastric mucosa. If the baby shows any abnormalities, it is recommended to take the baby to see a doctor promptly.
