A Weybridge teenager died after having an allergic reaction to painkillers he and a friend took at a party, an inquest heard.

Stephen Gurr, 19, died at St Peter’s Hospital, Chertsey, on February 18 this year, four days after he was taken there after taking Solpadol tablets at the party in Church Walk, Walton, Woking Coroner’s Court was told on Thursday, September 9.

Jamie Smith, one of Mr Gurr’s friends who was at the party, told the inquest he had swallowed "seven or eight" of the tablets with a friend who found them in the house on the morning of Sunday, February 14.

The tablets were a mixture of codeine and paracetamol, which can be obtained with a prescription, the inquest heard.

After taking the tablets, Mr Gurr immediately started “itching everywhere” and “threw up”, according to Mr Smith.

Mr Gurr’s mother, Lynn, then came to pick him up, after he called her at 7.30am to tell her he was unwell.

His condition deteriorated in the car and he was taken to hospital in an ambulance.

When he arrived he was nearly unconscious and was treated by staff, who believed he had suffered an anaphylactic shock.

Toxicology reports shown to the inquest revealed he had opiates, believed to be from the tablets he had taken, in his blood.

Mr Smith told the inquest they had been at a party in Walton on Saturday, February 13, but had gone to another house in Church Walk at about 6am on Sunday.

The house in Church Walk belonged to a middle aged woman called Angela Brewer, who Mr Smith described as a “mother-type figure” to another member of the party, Boy A, who cannot be named for legal reasons.

When the teenagers arrived, Ms Brewer was asleep upstairs, but Boy A got into the house from the back of the property.

Inside the house, Boy A found the prescription pills in a packet on a bed.

Mr Smith said: “[Boy A] said he felt like taking the tablets and opened them up and started sticking some in his hand and swallowed them and after that he said he was feeling drowsy.

I said ‘Do you want an ambulance?’ but he said he was fine. Steve [Stephen Gurr] then said he wanted to take some and put seven or eight in his hand and took some.

“After that he said he was itching everywhere over his body.

"He poured water all over his back and after that said he was feeling ill and threw up in the toilet.

"I said ‘You need to ring your mum, mate’. About 10 minutes later his mum arrived.”

The coroner, Dr Karin Englehart, asked Mr Smith whether he believed Mr Gurr was reacting to what he had just taken.

Mr Smith said: “Yeah, he was getting red lumps on his arms and his cheeks were pumping out.”

Mr Smith did not answer when asked by Dr Englehart whether anybody had told the teenagers not to take the tablets and said Ms Brewer had remained asleep upstairs during the incident.

Mr Gurr’s mother told the court her son had asthma and was an “allergic type”, but with no specific allergies.

She also said he was the type of person who could be easily led.

Mrs Gurr said: "He rang me at 7.30am and said he had taken something and he was having an allergic reaction to it.

"He didn’t seem too bad then.

"I drove straight to the party to take him to hospital.

"He was struggling to breathe.

"He said his throat was closing in and he was itching."

Surrey Police’s major crime team investigated whether there had been any suspicious circumstances surrounding the death, but Detective Constable Max Priestly told the inquest no charges were brought against anyone.

Boy A did not appear at the inquest, but in a statement read out, he said he had no recollection of the events that morning.

Dr Englehart recorded a verdict of accidental death.

She said: "Stephen Gurr died as a result of an anaphylactic reaction from a drug prescribed to someone else.

"He had no idea it would have the results it did."

The court also heard Mr Gurr’s death had resulted in three lives being saved because he had signed up to the Organ Donor register.
