May we suggest mouthwash?

A schizophrenic Bronx man with a compulsive habit of swallowing toothbrushes was hospitalized after shoving one down his gullet — only to be given another toothbrush by a city nurse, which he also gulped down before needing emergency surgery, he says in a new lawsuit.

Patient Randy Nero, 40, is suing Jacobi Medical Center for malpractice, arguing a nurse there should have known about his decades-long history of gobbling down the pearl-polishers, according to the suit filed Tuesday in Bronx Supreme Court.

He went to the city-run hospital in January to get removed a toothbrush he had swallowed.

Six months later, he was back for an unrelated visit in June 2018 when a nurse who should have known better handed him a personal hygiene kit containing another toothbrush — and left him alone in a bathroom, the suit alleges.

Needless to say, he gulped down that one too — and then required a three-hour emergency surgery to extract it, the papers say.

The incident made him bristle, because the hospital should have realized he had a problem, according to the suit.

“The patient reports that he has been swallowing toothbrushes since he was 18 years old when he heard of another person swallowing a toothbrush,” a medical report filed with the lawsuit says, noting he’s been hospitalized “100s of times” and has had “13 surgeries for stomach perforations, and many endoscopies to remove toothbrushes.

“Since then he began hearing voices telling him to swallow toothbrushes and how to do it. He reports that the voices are both male and female….he has learned to drown them out and they always talk about different ways of swallowing a toothbrush.”

He claims hospital staffers acted “negligently and carelessly,” causing him to suffer “severe psychological pain” and other injuries. It’s unclear how much cash he’s demanding in the lawsuit.

He suffers from an impulsive “a cognitive learning barrier” that also causes him to ingest batteries, according to the suit.

The hospital said that they can not comment specifically on any litigation.

“NYC Health + Hospitals is committed to delivering high quality health services with compassion, dignity, and respect to all, without exception,” a hospital spokesperson said in a statement.
