Case scenario

Margaret is a 71-year-old woman with type 2 diabetes, peripheral neuropathy, hypertension, osteoarthritis of the knees and obesity. She currently takes metformin modi­fied release (MR) 1 g daily, gliclazide MR 60 mg daily, rosuvastatin 10 mg daily, perindopril erbumine 4 mg daily, pregabalin 75 mg twice daily and paracetamol MR 1.33 g three times daily.

Last week, Margaret saw her podiatrist for a routine foot check and was advised to see her general practitioner (GP) as soon as possible, due to concerns about a foot ulcer. Margaret couldn’t see her regular GP, so consulted the out-of-hours service. She was prescribed amoxicillin-clavulanic acid 500 mg/125 mg twice daily.

Margaret visits the pharmacy today, with her husband, Bert. She asks for the repeat on the antibiotic prescription and Betadine ointment, as she ‘always ­finds it helps these things’.
