A 33-YEAR-old woman died from a toxic combination of a prescribed drug and alcohol, an inquest heard.

Olivia Butler of Stockton Rock, Kimbolton was taken to Hereford County Hospital on August 18 last year, when her partner found her unconscious in bed.

She was unresponsive to treatment and Ms Butler passed away on August 21.

The inquest at Herefordshire Coroner's Court heard a post mortem revealed her cause of death as pregabalin (a prescribed drug) and alcohol toxicity.

The pregabalin was significantly higher than therapeutic usage.

The inquest heard Ms Butler had been in a wheelchair since 2010. She fell from a balcony in Cyprus, where she was living, as she tried to rescue her cat.

Her partner, Alan Dovey, told the inquest Ms Butler would sometimes become frustrated with her injuries and hit her head on the floor.

On the evening of August 18 they had been out in Leominster drinking.

When they returned home Ms Butler tried to pick up their cats' bowls but she fell out of her wheelchair.

Mr Dovey tried to pick her up but she became agitated and she started to bang her forehead on the floor, which caused swelling.

He then helped her into her wheelchair and into bed, where she asked for a glass of water to take her medicine.

Half an hour later when he went back into the bedroom he found frothy liquid coming out of her nose and mouth, and she was unresponsive. He called an ambulance.

Mr Dovey said she had never spoken about taking her own life and was planning things for the future.

Her mum, Judy Owen, said she did not believe Ms Butler had taken an overdose deliberately as she was a fighter.

The inquest heard Mr Dovey was initially arrested on suspicion of GBH. Following a thorough investigation it was determined there were no suspicious circumstances and Mr Dovey was released without charge.

The post mortem noted the significance of the head injury caused by banging her head on the floor and the pneumonia, which ultimately led to her death.

Coroner Mark Bricknell said it was "a particularly sad case."

He recorded a narrative verdict that Ms Butler caused herself some injuries which did not lead to her death but she did ingest sufficient amounts of pregabalin and alcohol to cause her central nervous system to be depressed, which caused her death.
