The efficacy of growth hormone use is generally positively correlated with the duration of treatment, and the longer the duration of treatment, the more desirable the child’s final height in adulthood. At present, the clinical practice advocates long-term use of the drug, which can be applied as long as the epiphysis has not healed. Therefore, strictly speaking, there is no course of treatment for the use of growth hormone. We recommend three months as a period of observation, and you can decide whether to continue the treatment according to your actual needs and financial situation.
