Mechanism of Action
Stimulates growth; somatropin is similar to natural growth hormone; both preparations were developed with the use of recombinant DNA

Somatropin
Contraindications
Hypersensitivity to benzyl alcohol, creosol; closed epiphyses, intracranial lesions, acute respiratory failure, Prader-Willi syndrome with obesity, trauma
Somatropin
Side Effects

MS: tissue swelling, joint and muscle pain
SYST: ANTIBODIES TO GROWTH HORMONE
Somatropin
Nursing Considerations
- Signs/symptoms of diabetes
- Growth hormone antibodies if patient fails to respond to therapy
- Thyroid function tests: T3,T4,T7, TSH to identify hypothyroidism
