What Are Antibiotics?
Antibiotics are medicines that fight infections caused by bacteria. Examples include penicillin and ciprofloxacin. Sometimes antibiotics are given to prevent infection but only in special situations such as prior to some surgeries or when a person’s immune system has been altered (for example, if receiving chemotherapy).
Antibiotics are prescribed by a doctor, nurse practitioner or dentist, and obtained from a pharmacy. They can be in the form of pills or liquids. Antibiotics will come with directions for how much to take, at what times of day, along with other directions, such as “take with food” or “keep refrigerated.” Different types of antibiotics work in different ways and following instructions will ensure a better treatment outcome.
