Hello everyone- I'm looking for a bit of advice about a warfarin overdose. My mum (who was 86) had been poorly with a fractured pelvis as well as a tumour on her kidney (which she'd had for a few years)
She came out of hospital with a full care package because of her limited mobility but the carers were for personal care only and were not to give her medication. My sister & myself gave her this every morning.
However one day my sister had a note from the carer saying she had given mum her warfarin, meaning her dose that day was doubled. She called the doc who did a blood test and mums INR was a whopping 14.5 after being stable at 2.5 for a long time. Mum had to have a large dose of vitamin K the following day (this was between christmas & new year so out of hours doctors)
My question is - would just a single 'double dose' raise mums INR so drastically? Or could there be another reason for it?
Sadly mum displayed signs of another TIA the following day and had to be admitted to hospital where she died 3 weeks later.
Naturally my sister and myself would like to know if the overdose contributed to her death. We aren't out to make trouble but feel the care providers should be looking into why this happened and so far they seem to be ignoring it! any advice or ideas would be greatly appreciated thank you!
