What is intravenous (IV) therapy used for?

Intravenous (IV) therapy is specifically utilized for administering fluids, medications, and nutrients directly into the bloodstream via a needle or catheter that is placed into a vein. This method is particularly effective because it allows for rapid absorption and immediate physiological effects, making it critical in situations where quick intervention is necessary, such as in emergencies or for patients who cannot take medications orally.

Using IV therapy, healthcare providers can deliver hydration, manage electrolyte imbalances, provide essential medications, and support patients who are unable to ingest food or fluids by mouth. This direct access to the circulatory system ensures that the treatment can be tailored to meet the specific needs of the patient effectively.

Other methods of medication and fluid administration, such as muscle injections or oral intake, do not provide the same immediacy and precision as IV therapy. Therefore, it is the preferred route when rapid and controlled administration is essential.
