Hall said even her doctor's office was unable to persuade the pharmacist to fill the prescription.
"I was finally going to start seeing my body reflect my gender identity and the woman I've always known myself to be", she wrote.
Hilde Hall penned a blog post on the American Civil Liberties Union's (ACLU) website on Thursday stating that he was "humiliated" when a pharmacist at a CVS Pharmacy in Fountain Hills, Arizona, refused to fill a hormone therapy prescription in April.
Hall wrote that she's lucky that her family and friends accept and support who she is.
"He just kept asking, loudly, and in front of other CVS staff and customers, why I was given the prescriptions", Hall said in the blog post. I handed over the three prescriptions that my doctor, who specializes in hormone therapy, had just given me. She said she felt like the CVS pharmacist was "trying to out me as transgender in front of strangers".
Hall said the pharmacist "refused to fill one of the prescriptions needed to affirm my identity", adding that the unidentified pharmacist did not give her "a clear reason for the refusal". Eventually her doctor called the prescription into a local Walgreens where it was filled without question.
The pharmacist violated the company's policies and "does not reflect our values or our commitment to inclusion, nondiscrimination and the delivery of outstanding patient care", CVS said.
Hall said the pharmacist wouldn't return the prescription note. "Hilde said she was almost in tears by how the pharmacist was treating her, and no one should face that kind of judgment". CVS would not clarify whether the pharmacist was sacked, telling HuffPost that it does not comment on employment decisions.
"CVS Health extends its honest apologies to Ms. Hall for her experience at our pharmacy in Fountain Hills, Arizona last spring". The pharmacy isn't required to transfer refused prescriptions, but companies may make workplace polices that require referrals.
However, when went to a CVS in her hometown of Fountain Hills, Arizona, to fill the script, she was shocked by what came next.
Hall declined to take legal action against CVS after she received an apology.
CVS apologized to Hall for the delay, saying in its statement that no one had previously contacted her due to "an unintentional oversight".
The pharmacist violated company policies against denying patients access to medication prescribed by a physician based on a pharmacist's individual religious or moral beliefs, CVS Health spokesman Mike DeAngelis said Sunday.
Hall's incident comes as the Trump Administration is moving to roll back protections for transgender people in healthcare.
Skinner-Thompson said that holding companies like CVS accountable to anti-discrimination policies in high-profile instances helps further the LGBTQ rights movement.
