Warning

Information for general practitioners

Updated 2020

The aim of treatment is to suppress disease activity and preserve joint function in the inflammatory arthropathies and other rheumatic disorders.

Dosage

The same oral formulation must always be used:

  • 2.5 mg/kg/day in two divided doses for 6 weeks, increasing in 2-4 week intervals  to a maximum of 4 mg/kg/day in gradual 25 mg increments if necessary.  
  • 2.5mg -3.2 mg/kg/day often sufficient.  

Patients should receive annual flu vaccination and the pneumococcal vaccine.

 

Monitoring procedure

  • Pre-Treatment – FBC, U+E, CRP, LFT inc albumin, glucose, Hepatitis and HIV serology, BP

then   

  • FBC U+E, CRP, LFT inc albumin, BP and glucose - fortnightly until dose stable for 6 weeks then monthly for 3 months then 3 monthly.
  • Glucose and BP – every monitoring visit and maintain <140/90
  • Increase monitoring if NSAID changes or dose increases

 

Entering the results into a monitoring booklet will ensure that trends are not missed. Patients who do not attend for monitoring should be warned of the risk that serious adverse effects may go unnoticed. In the event of persistent failure to attend for monitoring please inform the Rheumatology department.

 

  • Creatinine rise by > 30% of base line over 12 months or less        
  • WC <3.5                                  
  • Platelets <140 x 109/l                                   
  • AST or ALT >100 - withhold and inform rheumatology
  • MCV >105
  • Neutrophils <1.6
  • Unexplained albumin <30mg/l
  • Unexplained eosinophilia >0.5
  • BP rise to abnormal range x 2, 2 weeks apart - discuss with rheumatologist
  • Abnormal bruising - withhold until FBC available

 

Duration of treatment and time to response

  • Treatment is continued indefinitely providing it remains effective and there are no significant side effects.  
  • Cyclosporin takes up to 3 months to become effective.
  • If no response at max tolerated dose at 3 months – withdraw.  
  • During this period there are likely to be continued symptoms or signs of disease activity. 
  • It is reasonable to use IM Depo Steroid (Kenalog 40 mg or Depo Medrone 80 mg) up to monthly, depending on the requirements of the individual patient. 
  • The dose required is small (e.g., monthly Kenalog 40 mg = 1.6 mg Prednisolone daily). 

 

Flares

  • Disease modifying drugs will not prevent all flares.
  • These can be managed with IM Depo steroid as outlined above. 
  • If flares become more frequent, or the disease fails to settle between flares, the dosage should be increased, or an alternative discussed with the rheumatologist.
