Her mother Lee posted a warning on Facebook this week.
"WARNING: watch out for drink spiking. My daughter was drugged at a nightclub."
Lee McCarthy said her daughter spent the night in hospital "virtually paralysed" and was visited by detectives the next day before she later gave a formal statement.
Her daughter was left "shaken and angry" after the incident.
"She wasn't the only one [drugged]", Lee wrote online. Since her first post the family had been told of several other alleged victims of Gold Coast drink spiking.
"We have had several girls msg us with info and similar stories which is helping."
She and her daughter were "110 per cent positive who did it" as they had spoken to another woman who was in the same booth as Ms McCarthy.
"The other girl was in hospital with Paige described being in the booth with the same person
Paige made her formal statement to the police this afternoon and they are taking it very seriously," Lee said.

She was flooded with messages of support by friends and strangers who hoped the person was caught and dragged before the courts.
"The police say it's very hard to prove these cases has to be very clear footage of the drug being put in the drink and given to the person so have to wait-and-see. I also said a few cases have gone to court recently with drink spiking and none of them have ended up in a conviction."
The nightclub said it had handed CCTV and information to police and was "very concerned" by the incident.
The Bedroom spokesman Matt Keegan told the Courier Mail that staff had combed the footage for clues as to what may have happened.
"Our review of her movements revealed no indication of drink-spiking by any third party in the venue," he said.
"At this stage, unfortunately, we're unable to comment much further, as it's the subject of an ongoing investigation."
A Queensland Police spokesman told news.com.au a complaint had been received about a drink spiking incident in Surfers Paradise on Sunday.
"The matter is under investigation. The Queensland Police Service does not identify individuals and will not be releasing any further information as the matter is ongoing."
Tomic made headlines when he sensationally quit the I'm a Celebrity jungle after three nights on the show. He was labeled a "quitter" at the time but said he had "never felt this bad".
"I don't need this now. I've never felt this bad in my life. This is the jungle. It's so different. Not what I expected. I need some peace.
"This is going to knock me around for a week, two weeks. I'm just not coping. It's too risky. I don't know if I can do it. I'd like to speak to someone," he said.
Channel Ten came under fire for its treatment of the news after a psychologist said he never should have been cast in the first place.
"I thought by coming here it would make me a super happy person ... I thought it would change me as soon as I got in," Tomic said.
"I thought I'd be super happy, camping for the first time, being around new people ... Half the time during the day, I'm just depressed," he confessed.
