How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
What happens
Reduced serum cortisol exposure, an increased risk of central (secondary) hypoadrenalism and attenuated growth-promoting effects of somatrogon-ghla
Interaction Deep Dive
Patients being treated with glucocorticoids replacement for previously diagnosed hypoadrenalism may require an increase in their maintenance or stress doses when receiving concomitant somatrogon-ghla therapy. Somatrogon-ghla inhibits 11-beta-hydroxysteroid dehydrogenase type 1, and conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue. Consequently, individuals with untreated growth hormone deficiency have relative increases in 11-beta-hydroxysteroid dehydrogenase type 1 and serum cortisol. Initiation of somatrogon-ghla may result in inhibition of 11-beta-hydroxysteroid dehydrogenase type 1 and reduced serum cortisol concentrations. Cortisone acetate and predniSONE may be affected more than others because conversion of these drugs to their biologically active metabolites is dependent on the activity of 11-beta-hydroxysteroid dehydrogenase type 1. In children, concomitant administration glucocorticoids and somatrogon-ghla may reduce the growth-promoting activity of somatrogon-ghla. Carefully adjust the glucocorticoid replacement dosing to avoid both hypoadrenalism and an inhibitory effect on growth1.
Why it happens (mechanism)
Inhibition of 11-beta-hydroxysteroid dehydrogenase type 1 in hepatic and adipose tissue; attenuation of growth-promoting effects of somatrogon-ghla
