Novichok attack victim Charlie Rowley has been discharged from Salisbury District Hospital, director of nursing Lorna Wilkinson has said.
Charlie Rowley, 45, and his girlfriend Dawn Sturgess, 44, were sickened after coming in contact with the nerve agent on June 29.
Novichok victim Dawn Sturgess died after spraying perfume laced with the nerve agent onto both her wrists, her boyfriend, who was also exposed to the deadly substance, has revealed.
Rowley's brother Matthew told The Sunday Telegraph his brother's memory about the incident is "vague", but the 45-year-old remembers handling a container that appeared to be a perfume bottle.
Sturgess initially collapsed at an address in Amesbury on June 30 and was taken to the hospital, police said.
Salisbury District Hospital said Mr Rowley had been through "an appalling experience most of us could never imagine".
The mother-of-three's death is being treated as murder.
The inquest heard that a "small glass bottle of fluid" containing Novichok had been found at Mr Rowley's home in Muggleton Road, Amesbury.
Britain blamed Russian Federation for the poisoning of the Skripals, who are recovering after lengthy hospitalizations.
Her sister Stephanie told the hearing she was present when doctors informed her of the decision to switch off her sibling's life support. The two spent weeks in critical condition but have since been discharged from the hospital.
Sturgess died on July 8 and the police have launched a murder investigation into the matter.
The Organisation for the Prohibition of Chemical Weapons earlier this week said its inspectors had collected samples in the Amesbury case and were analysing them. She is believed to have been exposed to 10 times as much Novichok as the Skripals.
British officials are "closing in on identifying the individuals they believe carried out the operation", according to the New York Times.
Park, where the restrooms are located, have suffered from Rookie Charlie Rowley and don Sturges visited during a walk.
When asked if the names of the suspects had been run past the Russian authorities, the Prime Minister's deputy official spokeswoman said: "This is an on-going complex investigation and I can't comment on the speculation around it".
The BBC has not been able to independently confirm the story.
