In adults with GHD, the FDA-approved labeling states that the starting dosage of GH should be very low ( to mg/day). The product labeling further states that this dose should be increased gradually on the basis of clinical and biochemical responses assessed at monthly intervals. The biochemical marker generally relied upon for GH is the IGF-I level in serum. Values of IGF-I should be maintained in the normal age- and sex-adjusted range. The literature indicates that the dose may be increased, on the basis of individual patient requirements, to a maximum of mg daily in patients younger than 35 years of age, and to a maximum of mg daily in patients older than 35 years of age. Of note, this dose is substantially less than GH replacement doses in children and adolescents, in whom the dose is based on weight.
