Steroids may change the daily pattern
Tablets, injections and high-dose inhaled or topical treatment can affect glucose differently. Prednisolone taken in the morning may cause a later rise, so fasting glucose alone can miss the problem. Monitoring should match the expected pattern.
Painkillers need kidney context
NSAIDs such as ibuprofen and diclofenac can contribute to acute kidney injury during dehydration, low blood pressure or existing kidney disease. Review over-the-counter use, duration and interactions rather than assuming every painkiller is harmless.
Coordinate the prescriber and diabetes plan
Tell the clinician prescribing steroids or pain treatment about diabetes, kidney disease and current medicines. If glucose rises, the adjustment may be temporary and should be planned rather than improvised.
Frequently asked questions
Should I refuse a steroid injection because I have diabetes?
Not automatically. Steroids can be clinically important. Discuss expected glucose effects, alternatives and a monitoring plan with the treating clinician.
Is paracetamol always safe?
It has different kidney and stomach risks from NSAIDs, but dose, liver health and other medicines still matter. Follow the label and clinical advice.
