SICK DAY RULESHelp Protect Your Kidneys

What to do if you…

  • Have a fever (high temperature) or feverish illness (COVID-19)
  • Develop vomiting and are unable to keep fluids down or have severe diarrhoea
  • Are being treated for an infection such as a chest infection or water (urine) infection

You should stop taking:

  • ACE inhibitors Examples include: ramipril, lisinopril, perindopril or another in the same group, all ending in “…pril”
  • ARBs / Sartans Examples include: losartan, irbesartan, candesartan or another in the same group, all ending in “…sartan”
  • Diuretics (water tablets) Examples include: furosemide, bumetanide, bendroflumethiazide, spironolactone, eplerenone, indapamide
  • Anti-inflammatory painkillers Examples include: ibuprofen, diclofenac, naproxen, celecoxib, etoricoxib
  • Metformin (used to treat diabetes)
  • SGLT’s (used to treat diabetes) Examples include dapagliflozin, saxagliptin, empagliflozin, canagliflozin.
  • This list is not exhaustive, if you are unsure whether your medicine belongs to one of these groups, please ask your pharmacist or doctor.


  • Drink plenty of fluids so that you avoid becoming dehydrated until your acute/sudden illness passes. This should be at least 7 cups a day (one cup = 200ml), unless you have other instructions from your doctor.
  • If you are vomiting, take small sips of water/fluid frequently until your symptoms have settled.
  • Avoid alcoholic drinks
  • Speak to your GP if you have passed much less urine than you normally pass, or if you are unable to keep fluids down or have diarrhoea or vomiting for longer than 48 hours. The doctor may need to take a blood test to check how well your kidneys are working.


Once you feel you are fully recovered and feeling back to your normal self you need to RESTART THE MEDICATION you have stopped.
