Moderate
Diclofenac × Iopromide
Non-steroidal anti-inflammatory drugs (NSAIDs)×X-ray contrast media. Watersoluble nephrotropic low-osmolar iodinated agents
Mechanism
Additive nephrotoxicity. NSAIDs reduce renal blood flow by suppressing vasodilatory prostaglandin synthesis; contrast adds tubular osmotic load. Contrast-induced AKI risk rises 2–3-fold.
Symptoms
Decreased urine output, rising creatinine, oedema, nausea. Symptoms develop 24–72 hours after contrast.
Management
Stop diclofenac 24–48 hours before elective contrast imaging; restart 48 hours after the study once creatinine normalises. With creatinine clearance below 60 mL/min, give IV isotonic hydration 6–12 hours before and 6–12 hours after imaging. Analgesic alternative: paracetamol up to 3 g/day.
