When an Elderly Parent Has a High Fever
Get urgent care / call 112 / 108 if there's confusion or drowsiness, difficulty breathing, chest pain, a stiff neck, a rash that doesn't fade, persistent vomiting, very low urine output, or they simply seem very unwell. In frail older adults, don't wait.
Why fever matters more in the elderly
Older adults can become seriously ill from infection quickly, and sometimes with surprisingly few classic symptoms. A fever — or even just new confusion, weakness, or "not being themselves" — can be the main sign of a significant infection that needs prompt treatment.
What to do
- Get a doctor's assessment promptly, especially if the fever is high, persistent, or they have other conditions.
- Keep them hydrated with sips of fluids if they're alert and able to swallow.
- Note other symptoms — cough, burning urine, pain, breathlessness, diarrhoea — to tell the doctor.
- Don't start antibiotics on your own — the cause needs to be identified.
In an older person, "just a fever" can be the tip of something serious like a urinary or chest infection heading toward sepsis. The threshold to get them seen should be low. A same-day doctor review is rarely an over-reaction.
