Generally speaking, the application of creams for children’s coughs is very harmless and mostly safe, because they are used externally, but in rare cases some harm can occur: first, it can cause damage to the child’s skin, and if the child’s skin is very sensitive, it may cause itching, rashes, redness and swelling. Green ointment can be applied to children for external application. Secondly, it can cause aggravation of cough symptoms. If the indications for applying cough patches are inappropriate, for example, patches containing cold medicines applied to children with wind-cold coughs can add to the cough symptoms, so the application of patches for children with coughs should also be done in accordance with medical advice.
