infantile hemangioma (iH) means that the endothelial cells of blood vessels have rapid proliferation and growth followed by spontaneous regression during childhood. Although physicians prefer a conservative approach, some complications with iH can occur and should be acted on sooner through observation in case further interventional treatment is required. Current research on propranolol for complicated iH has an equally effective response, but the optimal dosage and therapy duration in iH have not been fully established. This article explores low dose propranolol usage and clinical responses to it. Concern for home usage and safety are discussed. The results showed that patients were steadily getting better and improved color, texture and aspect of growth arrest in iH with low dose propranolol. The efficacy was the same as with results from past medical literature. Therefore propranolol treatment for iH must be given in appropriate dosage and safety monitoring after the patients were excluded from relative contraindications to propranolol. the main role of the older version of the drug propranolol is usually used for treating cardiovascular disease, propranolol treatment for iH have also been striking clinical effects. Propranolol is an old drug traditionally used in the treatment of cardiovascular disease, its new therapeutic effect for the treatment of iH has been noticed to be further investigated.
