Anabolic Steroid — Burns Hypermetabolism

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.

Dosing — no UK product information found

We found no UK product information (SmPC) for this medicine or presentation on the eMC or MHRA Products (checked October 2026). It may be unlicensed in the UK, imported, a medical device, or no longer marketed. ClinCalc Pro shows only doses it can trace to official product information, so none is shown — follow your specialist service or local guideline.

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.
