Do not allow patients with calcium channel blocker toxicity to eat after the ingestion, because they risk rapid mental status deterioration, including seizures, and may require intubation. Placement of an endotracheal tube when the patient has an empty stomach decreases the risk of aspiration. For these same reasons, do not administer ipecac syrup.

Orthostatic hypotension is a particular concern in patients who ingest calcium channel blockers. Limit the activity level of these patients to bed rest at the first clinical signs of calcium channel blocker toxicity.
