Linezolid
Linezolid is an antibiotic reserved for selected serious infections caused by susceptible Gram-positive bacteria. Its interaction and monitoring profile differs from many routine antibiotics.
Key points
- Linezolid treats specific bacterial infections and does not treat viral illness.
- Serotonergic medicines, medicines that raise blood pressure and some foods or drinks can cause important interactions.
- Agitation with fever or muscle rigidity, new visual change or unexplained bleeding needs urgent assessment.
Listings are for comparison only. Suitability and supply depend on clinician and pharmacy checks, stock, destination rules and prescription requirements.
What Linezolid is used for
Linezolid may be used for selected cases of pneumonia and skin and soft-tissue infection, particularly when resistant Gram-positive bacteria are suspected or confirmed.
How it works
Linezolid blocks bacterial protein production at an early stage. It also has monoamine-oxidase-inhibiting activity, which explains several medicine and food interactions.
Important safety checks
Antidepressants and other serotonergic medicines, decongestants, stimulants and foods high in tyramine require review. Blood counts may be monitored, especially with longer treatment or kidney impairment. Report new numbness, tingling or visual change promptly, and complete the prescribed course unless the treating clinician changes it.
When to seek urgent care
Seek urgent help for agitation or confusion with sweating, fever, diarrhoea, tremor or muscle rigidity; severe headache with very high blood pressure symptoms; new loss of vision; unusual bruising or bleeding; or a severe allergic or skin reaction.
