Prescribing Notes:

  • This treatment pathway covers formulary recommendations for people assigned male at birth wishing feminising hormone treatment in connection with gender dysphoria or incongruence. 
  • Further information is available via NHS Lothian RefHelp resources. 
  • Transdermal estradiol preparations are recommended for individuals over 40 and in patients with cardiovascular risk factors, high BMI, liver disease. 
  • For androgen suppression gonadorelin analogues (leuprorelin, goserelin or triptorelin) are preferred over cyproterone acetate. The three-monthly preparations are more commonly used. 
  • Cyproterone acetate is rarely used for androgen suppression due to reports of hepatotoxicity and increased risk of meningioma.  
  • Patients may require re-titration of estradiol following gonadectomy, when androgen suppression therapy can be stopped. All should re-engage with the GIC during this period, and the GIC will carry out this titration if indicated.
  • For prescribing Gonadotrophin-releasing hormone (GnRH) analogue (any medicinal product that consists of or contains buserelin, gonadorelin, goserelin, leuprorelin acetate, nafarelin or triptorelin), please refer to Scottish Drug Tariff part 12 Schedule 2 ‘Drugs to be prescribed in certain circumstances under the NHS Pharmaceutical services’ for items that must be endorsed ‘SLS’.
