Three masked crooks stuck-up a Queens pharmacy on Tuesday afternoon and made off with Xanax, Oxycodone and other prescription pills, authorities said.

“Don’t move if you want to live!” one of the crooks said as he pointed a gun at the Trinity Rx pharmacist in Glendale, store employee Mario Siha, 39, said.

The two other thieves then hopped over the counter and told Siha and the pharmacist to lay down on the ground and zip-tied their hands.

One of the crooks then showed Siha a list of prescription drugs they wanted to loot.

“I just remember the first one on the list,” Siha said. “It was Oxycodone.”

The fiends then rummaged through the shelves, grabbing Oxycodone, Xanax and other prescriptions before snatching Siha and the pharmacist’s wallets.

“We thought they were playing at first. Like trick-or-treating,” Siha said of the masked crooks.

No one was injured and the suspects are still at large, police said.
