IV antibiotics list: what to know

An IV antibiotics list is not a self-treatment guide: the medicine is selected for the infection, allergy history, kidney function and clinical situation. Different medicines cover different bacteria, and some are reserved for particular circumstances or given with close monitoring.

IV antibiotics enter a vein through a cannula and are used when prompt treatment is needed, infection is serious, or oral medicine cannot be taken or absorbed. A clinician may use examination findings, samples, previous treatment, allergies and kidney or liver function to choose a drug.

The name, dose and timing are individual decisions. Some medicines can affect the kidneys, liver, hearing, digestion or blood counts, so monitoring may be part of care. Never choose an IV antibiotic from a list found online or use another person’s prescription.

Give the care team a complete medicine and allergy history, including any previous severe diarrhoea after antibiotics. Ask what infection is being treated and how the response will be checked. Report rash, swelling, breathing changes, severe diarrhoea, unusual bruising, or pain and redness around the cannula.

Seek emergency help for facial or throat swelling, wheezing, trouble breathing, collapse or sudden confusion after treatment. Contact the treating team promptly for worsening infection symptoms, persistent vomiting, severe diarrhoea, or a painful, red or swollen cannula site.

Ask which antibiotic is planned, what it targets, why IV treatment is appropriate, what monitoring is required, how long treatment may continue, and whether a tablet option may become suitable.
