Introduction
Linezolid 600 mg/300 ml Injection is a strong antibiotic medicine used to treat serious bacterial infections. It is given through an IV (intravenous) drip in hospitals or clinics. Linezolid belongs to a group of medicines called oxazolidinone antibiotics, which work against bacteria that are resistant to many other antibiotics.
Doctors usually prescribe this injection when oral medicines are not enough or when a patient cannot take tablets.
Uses of Injection Linezolid
Linezolid is used to treat several serious bacterial infections, including:
- Pneumonia (lung infection)
- Complicated skin and soft tissue infections
- MRSA infections (Methicillin-Resistant Staphylococcus aureus)
- VRE infections (Vancomycin-Resistant Enterococci)
- Bloodstream infections caused by resistant bacteria
It is not effective for viral infections such as flu, COVID-19, or the common cold.
Ingredients of Linezolid Injection
Each 300 ml infusion contains: Linezolid 600 mg
How Linezolid Injection Works
Linezolid works by stopping bacteria from making the proteins they need to grow and survive.
Once the bacteria can’t make these proteins, they become weak and eventually die, helping the infection clear up.
Because it works differently from many other antibiotics, it is useful for infections caused by bacteria that don’t respond to other treatments.

- Standard Adult Dose: Linezolid 600 mg (one 300 ml infusion) every 12 hours
- It is given slowly through an IV drip over 30–120 minutes as instructed by a healthcare professional.

Important Notes:

- Never stop the treatment early, even if you feel better; incomplete treatment can cause antibiotic resistance.
