When using this page you should: ensure an individualised monitoring plan is developed in partnership with the patient and take account of any locally agreed advice and guidance.

Before starting


  • Baseline
    • Pregnancy testtwo tests 8-10 days apart in women of child bearing potential; exclude before initiating
    • Albumin
    • ALT or AST
    • Blood pressure
    • Full blood count
    • Height
    • Liver function tests
    • Serum creatinine (for creatinine clearance) or Calculated glomerular filtration rate
    • Vaccination status
    • Weight

Vaccination status

Consider vaccination against pneumococcus and influenza prior to starting treatment.

After started or dose changed


  • Every 2 weeks for minimum 6 weeks until dose stable; then 3 monthly
    • Albumin
    • ALT or AST
    • Full blood count
    • Serum creatinine (for creatinine clearance) or Calculated glomerular filtration rate

Ongoing once stable


  • At least every 12 weeks
    • Albumin
    • ALT or AST
    • Full blood count
    • Serum creatinine (for creatinine clearance) or Calculated glomerular filtration rate

Abnormal results

Respond to absolute levels

Consider stopping treatment and contacting a specialist any of the following develop:

Blood pressure

  • BP greater than 140/90mmHg. Manage in accordance with hypertension guidelines.

Full blood count

  • WCC less than 3.5 x 109/L,
  • Neutrophils less than 1.6 x 109/L
  • Unexplained eosinophilia greater than 0.5x 10 9/L
  • Platelets less than 140 x 109/l
  • Unexplained fall in serum albumin less than 30g/L
  • MCV greater than 105f/L then check B12, folate, thyroid-stimulating hormone levels. If abnormal treat; if normal discuss with specialist team.

Liver function

  • AST or ALT increase to greater than 100units/ml

Renal function

  • Creatinine increase greater than 30% above baseline over 12 months
  • Calculated GFR less than 60ml/min/1.73m2 (repeat in 1 week, if still more than 30% from baseline, withhold and discuss with specialist team)

Investigate if urinary protein

If urinary protein is at 2+ or more, a mid-stream urine sample should be taken, and:

  • if there is evidence of infection, this should be treated appropriately;
  • if the urine sample is sterile (no infection present) and the urinary protein 2+ or more persists on two consecutive measurements, stop mycophenolate mofetil and discuss with specialist team.


Advice to patients

Advise patients to seek urgent medical attention if they develop symptoms such as:

  • Skin or mucosal reaction (rash, pruritus, mouth or throat ulceration)
  • Sore throat
  • Fever
  • Unexplained bruising or bleeding
  • Nausea, vomiting, diarrhoea or weight loss
  • Diffuse alopecia
  • Breathlessness, infection or cough
  • Peripheral neuropathy
