Follow-up

Further Inpatient Care

Excluding long-acting preparations, patients with sympathomimetic toxicity who remain asymptomatic after 6 hours postingestion may be medically discharged.

Patients with ingestion of long-acting preparations typically should be monitored for 24 hours. Most of these patients are admitted to a telemetry floor or an intensive care unit.

Consider psychiatric evaluation before discharging patients from the hospital.

If inpatient care is required, it should be under the direction of a medical toxicologist or a physician with expertise in critical care.
