Piroxicam – are you still prescribing it?
The European Medicines Agency (EMEA) issued advice in 2007 on the use of the NSAID piroxicam. The
prescribing advice only relates to the oral, injectable, and suppository forms of the drug, not the topical skin
formulations & can be found on the EMEA website:
In summary piroxicam:
       should be limited only to the symptomatic relief of osteoarthritis, rheumatoid arthritis and ankylosing
        spondylitis, initiated by specialists, with gastro-protection co-prescribed . Alternative treatment should be
        considered at the patient’s next routine appointment.
       should not be used as a first-line treatment and the dose limited to a maximum of 20mg a day
In Herefordshire 3 practices are not prescribing any piroxicam – practices can check their NSAID prescribing on
the intranet:

Practice Review Points for patients taking Diclofenac 150mg/day
It may be appropriate for some patients to continue treatment with diclofenac; however, in some cases,
especially patients with significant risk factors for CV disease, consider alternatives:
1. Change to paracetamol 4g/day – may be less efficacious for some patients but certainly safer.
2. Change to 1200mg ibuprofen/day - reduces both their GI and CV thrombotic risk, especially if the
opportunity is taken to introduce a PPI for highest risk patients. High doses of ibuprofen (e.g. 2400mg/day) are
not prescribed frequently in clinical practice but may be required for full anti-inflammatory effect.
3. Change to naproxen 1000mg/day - reduces CV thrombotic risk, but may slightly increase their risk of GI
complications. However, if the opportunity is taken to introduce a PPI, the GI risks may also be reduced.
Priority Patients for Review:
People at high CV risk including: Patients with established CVD (e.g. check those prescribed aspirin, ACEI –
remember ACEI + NSAID increases risk of renal toxicity), diabetic patients, older men, smokers.
People at high GI risk including: older than 65 years; history of GI bleeding, ulcer etc; other meds that increase
risk e.g. prednisolone, aspirin, SSRIs; co-morbidity such as diabetes, hypertension, CVD, renal or hepatic
impairment; excessive alcohol; heavy smokers; max dose NSAID or long duration of treatment.
