MICA · FIRST-LINE LEARNING NOTES
Understand, prioritise and organise follow-up
An NSAID provides symptom relief; its benefit must be weighed against gastrointestinal, kidney, cardiovascular and infectious risks, including during short courses or self-medication.
Define the expected benefit
Identify the cause of pain, functional impact and useful alternatives before considering an NSAID. Do not automatically renew an ineffective treatment. During infection, NSAIDs can reduce pain and fever, delay diagnosis and be associated with serious complications. Improvement in those symptoms alone therefore does not demonstrate recovery.
[1][2][3]Assess individual risk
Check previous ulcer or bleeding, kidney impairment, heart failure, cardiovascular disease, hypertension, pregnancy and previous NSAID reactions. Intercurrent dehydration changes kidney risk. Establish actual use, including non-prescription products: two different brands may contain two NSAIDs. Age and comorbidity influence selection and monitoring.
[2][4]Check whether the expected benefit justifies gastrointestinal, renal and cardiovascular risk. Gastric protection does not prevent kidney injury or fluid retention. Combining an NSAID with a diuretic and a renin–angiotensin system blocker requires particular renal caution. Infection may worsen despite reduced pain or temperature during symptomatic treatment.
[4][1]Make prescribing safer
Review anticoagulants, antiplatelets, corticosteroids, diuretics and renin–angiotensin system medicines. Gastroprotection, when indicated, does not prevent kidney or cardiovascular toxicity. If an NSAID is chosen, use the lowest effective dose for the shortest appropriate duration, following product information. Plan clinical and laboratory monitoring according to individual risk.
[4][2]Recognise intolerance promptly
Review pain relief, function, blood pressure, oedema and kidney function when relevant. Black stools, vomiting blood, reduced urine output, breathlessness or an allergic reaction require prompt assessment, with emergency care when appropriate. Reassess a worsening infection rather than simply extending the NSAID. Give a clear review date or trigger.
[4][1]A learning situation
FICTIONAL CASE · SELF-REFLECTION WITHOUT A SCORE
A patient with hypertension taking a diuretic and a renin–angiotensin system inhibitor requests an NSAID for back pain. Diarrhoea has reduced oral intake for two days, and they already take an over-the-counter painkiller.
Which risk immediately changes the decision?
Read the reasoning
Dehydration, concomitant medicines and possible duplication increase kidney risk. Identify the existing product, assess hydration and consider a suitable alternative. Adding gastroprotection alone does not resolve the problem: prescribing requires an overall risk assessment and monitoring plan.
