Before starting
Consider
- Baseline
- Blood pressure particularly before COX-II inhibitors
- Estimated glomerular filtration rate
- Full blood count
- Serum creatinine
- Liver function tests if hepatic impairment
After started or dose changed
Consider
- Within 2 weeks
- Estimated glomerular filtration rate or Serum creatinine (for creatinine clearance)
- Full blood count
- Liver function tests if hepatic impairment
- Within 4 weeks; within 2 weeks if etoricoxib
- Blood pressure
- Within 4 weeks
- Haemoglobin if high risk of gastrointestinal effects
Ongoing once stable
Consider
- Periodically
- Blood pressure in elderly, high risk patients, and patients taking COX-II inhibitors
- Estimated glomerular filtration rate in renal impairment or where other drugs affecting renal function (e.g. ACE inhibitors)
- Full blood count
- Liver function tests in liver impairment or patients on long-term NSAIDs
Notes
When to consider NSAID monitoring
NSAID monitoring may be particularly important where patients are elderly, or where there is other clinical concern which may include but is not limited to:
- ischaemic heart disease
- cardiovascular disease
- cerebrovascular disease
- peripheral vascular disease
- heart failure
- gastrointestinal disease
- renal disease
- taking drugs which may interact
Good prescribing practice
Always use NSAIDs at the lowest effective dose and for the shortest possible duration. Consider risks and response to treatment. Enquire about, and manage, adverse effects. Use clinical judgement to decide what must be monitored and how frequently. Routinely appropriateness regularly, particularly in the elderly and high risk patients.
