Dosing instructions

To start

  1. Before initiating therapy, measure serum IGF-I level concentration and run liver tests to establish a baseline.

  2. Under physician supervision,* give a 40-mg loading dose of SOMAVERT® (pegvisomant for injection).1

  3. Beginning the next day, have the patient self-administer daily subcutaneous injections of SOMAVERT 10 mg.1

To titrate

  1. Every 4 to 6 weeks, measure serum IGF-I levels.

  2. Based on IGF-I levels, titrate SOMAVERT dose in 5-mg increments or decrements until IGF-I levels are maintained within age-adjusted normal range.1

  3. The maximum daily maintenance dose should not exceed 30 mg/day.1

  4. Continue checking IGF-I level concentrations at least every 6 months after IGF-I levels have normalized.1

See full prescribing information for initiation and continuation of treatment with SOMAVERT based on results of liver tests.
