Hemangiomas are treated by injections, but specific side effects vary depending on the drug injected and the patient’s absorption response. Common side effects considered are subcutaneous redness and swelling or localized fever, some of which are easily complicated by infection, and in severe cases, pus may appear. Individual injections may produce relatively specific side effects, for example, the clinical application of hormone or urea injections for hemangiomas will produce symptoms of frequent and urgent urination. If chemotherapeutic drugs are used, such as pingyangmycin and bleomycin, these drugs can cause hair loss, nausea, and vomiting. Therefore, the emergence of hemangioma for intramuscular or subcutaneous injection must be carefully selected, try to choose the injection of drugs with fewer side effects and relatively stable to the condition of the drug, so as to minimize the production of side effects.
