An Alta Sierra man is in county jail after allegedly poisoning his girlfriend with Visine.

The woman, who was not identified, contacted the Nevada County Sheriff’s Office Tuesday night to report her boyfriend has been poisoning her, according to dispatch reports.

Shayne Curtis Carpenter, 27, had been arguing with the victim when he placed several drops of Visine in her drink, said Sgt. Dan Saunders.

According to Saunders, the woman sought treatment at Sierra Nevada Memorial Hospital, was treated and released.

“It definitely will cause nausea and vomiting,” Saunders said.

Visine contains tetrahydrozoline, which can cause symptoms that include difficulty breathing, blurred vision, changes in blood pressure, nausea and vomiting, tremors or seizures, coma and low body temperature. Contrary to popular belief, Visine will not cause diarrhea.

Carpenter was arrested Thursday on suspicion of willful poisoning and spousal abuse and was being held in lieu of $25,000 bail.
