Oxandrolone
Brand names: Oxandrin, Anavar
Oxandrolone is a synthetic oral anabolic-androgenic steroid that has been used as an adjunct in severe burns to attenuate catabolism and support lean body mass and wound healing during the hypermetabolic phase.
ClinCalc Pro is rebuilding its dose data from primary open sources — the manufacturer SmPC (eMC), the WHO Model Formulary and other official references — under clinician review. This drug's structured dose is not yet published here. Confirm all doses against the product SmPC and your local formulary before prescribing.
Clinical monograph
How it works
As an androgen-receptor agonist with relatively anabolic activity, it promotes protein synthesis and nitrogen retention, helping to counter the profound muscle catabolism seen after major burn injury.
Prescribing in practice
- Hepatotoxicity, including cholestasis and abnormal liver function, is a key concern with oral anabolic steroids, so monitor liver function during treatment.
- It can cause virilising and androgenic effects and adversely affect lipid profile, and is contraindicated in pregnancy.
- Use is specialist and adjunctive within burns rehabilitation; prescribe against current prescribing references as availability in the UK is limited.
Monitoring
Monitor liver function and lipid profile, alongside clinical markers of nutritional and functional recovery, during therapy.
Counselling the patient
- Explain that this medicine is used to help rebuild muscle and aid recovery after a major burn.
- Advise reporting jaundice, dark urine, abdominal pain or unusual swelling.
- Discuss potential androgenic effects and the need to avoid pregnancy.
Evidence & guidelines
Anabolic support in severe burns has been studied with oxandrolone showing benefits on lean mass in burns rehabilitation; use remains specialist and guided by current prescribing references.
