DD has had a UTI before (& been admitted to hospital with a temp of 41.4). Paracetamol will bring temperature down but we and the hospital found that child ibrufen was always far better at bringing the temperature down - we interspaced the 2 as they don't react with one another. NHS direct told us not to do this but hospital/GP's have always done it.
If you can can you get a sterile container and a wee sample to take to the doctors for them to send away for cultures? We keep a sample bottle upstairs just in case after the first UTI! Though I'd imagine you could use a glass container or something if it was sterilised.
Recent experience with high temp 40.2 + a&e said very high temps which are only v temporarily bought down with calpol are normally due to throat or UTI. DD subsequently developed a chest infection and tonsillitis so they were right. Hope it's just a cold but worth getting her checked out.
At least if she's toilet trained it might be easier getting the sample - trying to get a sample from and 18 month old unpotty trained child took hours (& multiple misses with me taking my eyes off her at the critical moment!)
rang NHS direct got a message saying they were only taking emergency calls & they were very very busy. So I did the online symptom checker instead which said I should phone GP or if surgery was closed, OOH.
Just been on the phone to OOH who said she needs to be seen & am waiting for reception to call me back with appt time . OOH is at the hospital & parking is shocking, not sure whether to get a taxi instead
