- Linezolid should only be initiated in a hospital environment and after consultation with a relevant specialist such as a microbiologist. In exceptional circumstances it may be considered appropriate for a GP to commence treatment in a primary care setting (off-license use), only under the recommendation and supervision of a microbiologist. This should be discussed on an individual patient basis.
- Linezolid should only be used for life-threatening or deep seated infections due to MRSA where alternate therapy, e.g. vancomycin, is unsuitable. Linezolid is not active against infections caused by Gram negative pathogens. Specific therapy against Gram negative organisms must be initiated concomitantly if a Gram negative pathogen is documented or suspected.
- The maximum treatment duration is 28 days. The safety and effectiveness of linezolid when administered for periods longer than 28 days have not been established.
- BNF CHM advice
Severe optic neuropathy may occur rarely, particularly if linezolid is used for longer than 28 days. The CHM recommends that:
- patients should be warned to report symptoms of visual impairment (including blurred vision, visual field defect, changes in visual acuity and colour vision) immediately;
- patients experiencing new visual symptoms (regardless of treatment duration) should be evaluated promptly, and referred to an ophthalmologist if necessary;
- visual function should be monitored regularly if treatment is required for longer than 28 days.
Haematopoietic disorders (including thrombocytopenia, anaemia, leucopenia, and pancytopenia) have been reported in patients receiving linezolid. It is recommended that full blood counts are monitored weekly. Close monitoring is recommended in patients who:
If significant myelosuppression occurs, treatment should be stopped unless it is considered essential, in which case intensive monitoring of blood counts and appropriate management should be implemented.
- receive treatment for more than 10–14 days;
- have pre-existing myelosuppression;
- are receiving drugs that may have adverse effects on haemoglobin, blood counts, or platelet function;
- have severe renal impairment.
Spontaneous reports of serotonin syndrome associated with the co-administration of linezolid and serotonergic agents, including antidepressants such as selective serotonin reuptake inhibitors (SSRIs) have been reported. Co-administration of linezolid and serotonergic agents is therefore contraindicated except where administration of linezolid and concomitant serotonergic agents is essential. In those cases patients should be closely observed for signs and symptoms of serotonin syndrome.

- For patients with Cystic
Fibrosis (CF) treatment should only be prescribed by
- Colistimethate sodium injection is included for nebulised use in non-CF patients with bronchiectasis.
- Colistimethate sodium dry powder for inhalation is recommended as an option for use in line with NICE TA276: Colistimethate sodium and tobramycin dry powders for inhalation for treating pseudomonas lung infection in cystic fibrosis (March 2013)
- Tablets 550mg (£259.23 = 56 tablets)
- 550mg twice a day
- The clinical benefit of rifaximin was established from a controlled study in which subjects were treated for 6 months. Treatment beyond 6 months should take into consideration the individual balance between benefits and risks, including those associated with the progression of hepatic dysfunction.
Rifaximin should be co-prescribed alongside lactulose (or alternative laxative) sufficient to open bowels twice per day.
- Treatment with rifaximin should be initiated by a Gastroenterology Consultant. Once the patient is stabilised on treatment repeat prescriptions may be issued by primary care, however the ongoing management of the patient's liver disease will continue to be the responsibility of secondary care.
- Rifaximin is a non-absorbed antibacterial agent and there are no specific monitoring requirements associated with treatment.
- Secondary care will monitor the ongoing need for continuation of rifaximin in individual patients
- NICE TA337 Rifaximin is recommended, within its marketing authorisation, as an option for reducing the recurrence of episodes of overt hepatic encephalopathy in people aged 18 years or older (March 2015).
- Tablets 200mg
- Powder for concentrate for solution for infusion 200 mg
