Miami psychiatrist fined for prescribing controlled substances to her lover
Almost four years of prescribing her lover psychiatric drugs will cost a Miami psychiatrist $10,000, part of her punishment from the Florida Board of Medicine.
Dr. Ana Marietta Castellanos, also an FIU assistant professor for psychiatry and behavioral health, will pay a $5,000 fine, $5,000 in Florida Department of Health case costs and has to complete continuing medical education courses in laws, rules and ethics; record keeping; and risk management.
“The prevailing professional standard of care required [Castellanos] a) refrain from prescribing controlled substances for psychiatric treatment to a romantic partner on an ongoing basis and b) refer the patient to another provider for psychiatric treatment,” the Department of Health’s administrative complaint said.
Castellanos’ online Department of Health profile shows no other discipline since becoming licensed in Florida in May 2000. She answered neither email nor a phone call from the Miami Herald.

According to the complaint, Castellanos started a “romantic relationship” in January 2018. Her relationship partner “suffered a traumatic brain injury” on New Year’s Eve 2018.
“From Mar. 29, 2018 through Feb. 2, 2022, [Castellanos] prescribed controlled substances for psychiatric treatment” including what’s called “generic Adderall” and Adzenys XR-ODT, drugs used for treatment of ADHD in children and adults; anxiety drug diazepam, sold under the brand name “Valium;” and tramadol, used for “moderate and severe pain.”
During this time, the complaint said, Castellanos didn’t refer her relationship partner to anyone for psychiatric treatment nor did she “create medical records that justified the course of treatment.”
