The word 'hypodermic' is often used to describe a type of needle that is used for medical purposes, such as giving injections or drawing blood. It is also used to describe medications that are injected directly into the body, rather than being taken orally. So, if you hear this word in a medical setting or read it in a health-related article, it probably refers to something that involves needles or injections.
