This inhibition could theoretically decrease the efficacy of tamoxifen, which could hypothetically lead to higher breast cancer recurrence rates and mortality. There is inconsistent data reported on the potential drug\u2013drug interaction between concomitant use of tamoxifen and CYP2D6\u2010inhibiting antidepressants.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim<\/jats:title>\n                    <jats:p>We investigated prescribing patterns of concomitant tamoxifen and antidepressant medications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p>Our study population included adult women \u2265 age 18, with stage 0\u2013IV breast cancer who were treated at the Cleveland Clinic, received tamoxifen, and were concurrently prescribed at least 1 antidepressant medication. Patients diagnosed between 2016 and 2021 were identified from a tumor registry database. Among the 405 included patients, 74.8% were taking at least 1 antidepressant before initiating tamoxifen, while 25.2% were started on antidepressant therapy after beginning tamoxifen. Following tamoxifen initiation, 66.3% of patients who had been on an antidepressant continued with the same medication. Among those who switched antidepressants, 16.8% changed to a serotonin\u2010norepinephrine reuptake inhibitor (SNRI), 12.8% changed to a different selective serotonin reuptake inhibitor (SSRI), and 2.6% changed to another class of antidepressant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>There is awareness of tamoxifen and antidepressant interaction among healthcare providers. However, differences in prescription patterns across providers exist. Individualizing care and, when appropriate, opting for antidepressants with weak or no CYP2D6 inhibition that are equally effective in treating mood disorders or other conditions may be important. While no adherence or outcomes data are presented here, a collaborative, interdisciplinary approach may help support consistent and effective oncologic and behavioral health patient care.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/cnr2.70608","type":"journal-article","created":{"date-parts":[[2026,6,22]],"date-time":"2026-06-22T03:59:08Z","timestamp":1782100748000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessing Practice Patterns of Antidepressant Medication and Tamoxifen Use Among Patients With Hormone Receptor\u2010Positive Breast Cancer"],"prefix":"10.1002","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6207-2371","authenticated-orcid":false,"given":"Nerea","family":"Lopetegui\u2010Lia","sequence":"first","affiliation":[{"name":"Division of Medical Oncology, Department of Internal Medicine The Ohio State University Comprehensive Cancer Center  Columbus Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Murray","sequence":"additional","affiliation":[{"name":"Integrated Surgical Institute Cleveland Clinic  Cleveland Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariah","family":"Ondeck","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Cleveland Clinic  Cleveland Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bennett","family":"Osantowski","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Cleveland Clinic  Cleveland Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sowmya","family":"Takkellapati","sequence":"additional","affiliation":[{"name":"Department of Hematology\/Medical Oncology Taussig Cancer Institute, Cleveland Clinic  Cleveland Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Quantitative Health Sciences Cleveland Clinic  Cleveland Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amanda","family":"Maggiotto","sequence":"additional","affiliation":[{"name":"Department of Hematology\/Medical Oncology Taussig Cancer Institute, Cleveland Clinic  Cleveland Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Halle C.
