Medicine Sick Day Guidance

Medicines and Dehydration “Medicine Sick Day Guidance”

You can become dehydrated from vomiting, diarrhoea or fever (high temperature, sweats, shaking).  If you are sick or have diarrhoea once, then you are unlikely to become dehydrated. Having two or more episodes of vomiting or diarrhoea or having a prolonged fever can lead to dehydration.  Taking certain medicines when you are dehydrated can result in you developing a more serious illness.

Medicines that make dehydration more likely are:

Diuretics Sometimes called “water pills”                          eg Furosemide, spironolactone, bendroflumethiazide

Medicines that can stop your kidneys working if you are dehydrated are:

ACE inhibitors      Medicine names ending in “pril”                        eg Lisinopril, perindopril, ramipril

ARBs                      Medicine names ending in “sartan”  eg Losartan, candesartan, valsartan

DRIs                       Medicine working on the kidneys      eg Aliskiren

NSAIDs                  Anti-inflammatory pain killers                            eg Ibuprofen, diclofenac, naproxen

Medicines that make you more likely to have a side effect called lactic acidosis if dehydrated are:

Metformin             A medicine for diabetes

Medicines that make you more likely to have a side effect called diabetic ketoacidosis (DKA) if dehydrated are:

SGLT2’s Medicine names ending in “gliflozin” eg Canaglifozin, Dapagliflozin, Empagliflozin

“Medicine Sick Day Guidance”

If you develop a dehydrating illness, then it is important that you discuss your condition with a medical professional. This may be your GP, Nurse or Pharmacist. You may be advised to discontinue taking medications which lower your blood pressure for a short time and a blood test will be arranged to check your kidney function. Remember to keep drinking small amounts of fluid regularly on your sick days too. If you are only passing small amounts of urine you may need admission to hospital and you should alert your GP or Out of hours service to this.
