autoindicarse

Used specifically in medical/pharmaceutical contexts for taking medication on one's own judgment, without a doctor's prescription — almost always appears in warnings against the practice.

• Autoindicarse antibióticos sin receta es un riesgo para la salud. — Self-prescribing antibiotics without a prescription is a health risk.
• Muchos pacientes se autoindican analgésicos sin consultar al médico. — Many patients self-prescribe painkillers without consulting a doctor.
• La farmacéutica advirtió sobre los peligros de autoindicarse. — The pharmacist warned about the dangers of self-prescribing.

Narrower than automedicarse, its far more common near-synonym — autoindicarse specifically emphasizes deciding on the treatment, while automedicarse is the everyday word most speakers actually reach for.
