Intravenous drug user
Intravenous drug users (IVDU) (also known as intravenous drug abusers (IVDA)) are patients who self-inject recreational drugs, most commonly heroin, although many other agents are frequently injected, including cocaine, prescription opioids and methamphetamine.
Intravenous drug users may present due to a variety of complications:
- at/close to the injection site
- remote from the injection site
- related to the drug itself or excipients
- allergic reaction
- hypogonadism in heroin use 2
IVDU patients are also at increased risk of disease due to often having other risk factors for disease, including long term tobacco use, chronic alcohol excess, malnutrition, poor living conditions, etc. e.g. pneumonia 2.
