What is a bolus dose?

A bolus dose is a single, large dose of medication given quickly and all at once, usually through an injection or intravenous (IV) line. This type of dosage is often used in emergency situations when rapid and powerful effects are needed. Bolus doses can also be used in certain medical procedures, such as during anesthesia induction or to quickly increase drug levels in the bloodstream. The dose and rate of administration of a bolus dose are carefully controlled to avoid adverse effects, such as overdose or toxic reactions. Patients receiving bolus doses are closely monitored to ensure safety and efficacy.
