What Are Intravenous Antibiotics?

Intravenous antibiotics are medication that are designed to kill bacteria and that are delivered directly into the bloodstream. Intravenous antibiotics are used in place of other kinds of antibiotics such as those taken orally or applied topically. While the mode of use may be different, the purpose of these antibiotics are all the same. Often, antibiotics are available in oral and intravenous forms.

Intravenous antibiotics work just like all other kinds of antibiotics. They are meant to either kill bacteria and to stop the infection from spreading. And, just like other oral and topical antibiotics, intravenous antibiotics may either be designed to deal with a wide range of bacteria or to target specific kinds of bacteria. It is thus important to get a prescription when taking antibiotics, as not all antibiotics work in the same way.

The main reason for choosing to use intravenous antibiotics instead of the oral or topical kind is that intravenous antibiotics work much more quickly. This is to be expected as the drug is delivered directly into the blood stream. When a patient is in a critical condition, speed is of paramount importance, and intravenous antibiotics are usually the treatment of choice.

Intravenous antibiotics are usually administered via an intravenous catheter. A saline solution contained in a bag or bottle may be connected to the catheter. There are two ways by which the antibiotic can be administered: either directly into the catheter or into the saline solution. The latter is done if it is necessary to deliver the antibiotic in small doses.
