Gender-affirming pharmacotherapy and additional health considerations: A contemporary review

Background: Transgender and gender-diverse (TGD) individuals in the United States face health care disparities compounded with discrimination and limited access to necessary medical services. Gender-affirming interventions have been shown to mitigate gender dysphoria and psychiatric comorbidities, yet United States legislation limiting such interventions has increased. As medication experts, pharmacists can facilitate access to care and appropriate use of gender-affirming hormone therapy (GAHT) and educate other health care providers on best practices for caring for TGD individuals in a variety of settings.Objectives: To provide pharmacists with a contemporary review of GAHT and associated medication-related concerns.Methods: We searched PubMed for articles published until December 2022. MeSH terms such as transgender, transsexual, gender diverse, gender variant, or gender nonconforming in combination with phrases like gender-affirming care, treatment, pharmacotherapy, or hormone therapy were used to capture desired articles. Results: Feminizing hormone therapy (FHT), such as estrogen and antiandrogen agents, increases female secondary sex characteristics while suppressing male secondary sex characteristics. Masculinizing hormone therapy (MHT) achieves male secondary sex characteristics and minimizes female secondary sex characteristics using testosterone. For both FHT and MHT, the choice of therapy and formulation ultimately involves the patient's treatment goals, preferences, and tolerability. GAHT has additional health considerations pertaining to renal drug dosing, fertility, cardiovascular, and cancer risks. Pharmacists may provide crucial guidance and education to both patients and health care providers regarding risks associated with GAHT.Conclusion: Many pharmacists feel unprepared to help provide, manage, and optimize GAHT. For many TGD individuals, GAHT is medically necessary and a life-saving treatment. Therefore, pharmacists should be provided tools to close knowledge gaps and improve their ability to care for these patients. By offering a thorough updated overview of GAHT, pharmacists can gain confidence to provide appropriate care for this increasingly visible population.(c) 2023 American Pharmacists Association (R).
