A mother of two died from a severe allergic reaction to medication she had been given by her dentist, an inquest has heard.

Marian Carrick suffered a heart attack after taking a single anti-biotic amoxicillin tablet.

The 46-year-old collapsed at her home in Reeves Lane, Wing, Rutland, after taking the drug.

An inquest at Loughborough Coroner's Court was told her neighbour, a retired GP, and ambulance staff tried to save her, but she was pronounced dead at hospital about an hour-and-half later.

Yesterday's inquest heard Mrs Carrick fell ill on August 29, 2007, the same day she had collected the medicine from her dentist in Uppingham.

Pathologist Dr Angus McGregor, who carried out a post-mortem examination, said Mrs Carrick had taken amoxicillin before, without suffering any ill effects, but on this occasion she had suffered a severe reaction to the tablet.

He said: "The cause of death was a severe anaphylactic reaction, a severe allergic reaction.

"That can lead to shock. That can lead to massive circulatory failure, and the heart and circulation fails."

Dr Colin Reid, a consultant in emergency medicine for the University Hospitals of Leicester, told the inquest Mrs Carrick's medical records showed no evidence of previous allergy to any drugs.

He said: "Anaphylaxis is sometimes unpredictable, as it appears to have been in this case."

Dr Reid said technicians from the East Midlands Ambulance Service arrived just before 5pm to find former doctor and neighbour, Charles Gallimore, with Mrs Carrick.

The inquest heard Mr Gallimore, who had been a GP for more than 40 years, advised them to give her adrenaline to restart her heart.

However, Dr Reid said the technicians, who are qualified just below the level of full paramedics, were not permitted, under their training, to administer adrenaline.

Mrs Carrick was eventually given adrenaline when a full paramedic arrived at 5.35pm.

Her brother Steve Jones told the inquest he thought the technicians should have used adrenaline earlier to try to save his sister.

He said: "There was half an hour between the first and second ambulance. For half an hour, they carried on with giving cardio-vascular therapy, but never thought once to give her adrenaline when there was a doctor of 40 years' experience begging them to do it.

"I'm not sure she had anything to lose.

"The technicians weren't qualified to deal with the situation."

Dr Reid said: "This would have been a difficult situation for the attending crew. They would have had no way of knowing if this person (Mr Gallimore) was medically trained.

"They acted appropriately and professionally, and provided the best medical care they could."

Coroner Carolyn Hull recorded a verdict of misadventure.

She said: "I offer all members of the family condolences on the death of a mother in the prime of her life. This was a tragic set of circumstances."
