IV infusion

Slow medicinal drip

An IV infusion is the slow, controlled delivery of fluids, medications, or nutrients directly into a vein through an intravenous line.

Unlike a quick injection, an infusion drips steadily over minutes or hours: The chemotherapy was administered as a four-hour IV infusion.

Medical settings use infusion pumps to regulate the rate precisely.
