The side effects of foot patches on children are negligible. The reason why foot patches are considered to be less effective on children is based on the following reasons. First of all, the foot patch is a topical treatment, and the effect on the child is very mild when applied topically to the child’s feet. The drug cannot effectively enter the child’s bloodstream and will not cause significant liver or kidney damage. Because only oral drugs or intravenous drugs can enter the child’s liver and intestinal circulation in large quantities. Secondly, the medicine of foot patches is relatively safe, most of the foot patches are made due to Chinese medicine preparations, most of the Chinese medicine belongs to plant-based drugs, these drugs are natural and the stimulation for children is very mild. Based on the above two points, parents can safely apply foot patches to their children.
