RT insertion, or Rapid Tranquilization insertion, refers to the administration of medication to quickly and safely calm an agitated or aggressive individual who may pose a risk to themselves or others.

The decision to use RT insertion is made when non-pharmacological interventions have been ineffective or are not feasible, and the individual's behavior poses an immediate threat. The specific medications used for RT insertion can vary depending on the patient's condition and the healthcare facility's protocols. Common medications used may include benzodiazepines, antipsychotics, or sedatives.
