A Manhattan movie producer said she took an extra dose of her prescription painkiller -- along with Benadryl -- and could have drunk alcohol at the Hampton Classic before crashing her Mercedes sport utility vehicle in Water Mill, according to court documents.

Lisa Maria Falcone, 48, the wife of an embattled New York City hedge fund manager, is due back in Southampton Town Justice Court on Oct. 3 on charges of driving high on alcohol and drugs and driving without a license, prosecutors said Wednesday.

Her speech was slurred, police said, and she had an odor of alcohol on her breath Saturday. She performed poorly in sobriety tests after the crash at Montauk Highway and Hayground Road.

"I take Neurontin," Falcone said, according to a report by Southampton Town Police. "I usually take 900 mg a day. Today, I took 1,200 mg all at once because my ankle was hurting and it helps my pain."

The Benadryl was for her allergies, she said in the report. Neurontin is prescribed for nerve pain.

Police said Falcone, executive producer for the film "127 Hours," said she doesn't drink alcohol but may have had a lemonade containing alcohol at the horse show.

Police said Falcone's breath analyzer reading was 0.03 percent; the legal limit is 0.08 percent. She was arraigned Sunday and released on her own recognizance, records said.

Police said Falcone was driving south on Hayground Road when she bumped a convertible from behind and both vehicles hit a parked truck. No one was hurt in the 2:25 p.m. accident.

Ed Burke Jr., Falcone's attorney, noted his client's breath analyzer reading was below the legal limit.

In June, the Securities and Exchange Commission filed fraud charges against her husband, Philip Falcone, and his company, Harbinger Capital Partners.
