PEMBROKE PINES, Fla. -- Four students from the same South Florida school were rushed to the hospital after consuming energy drinks.

It happened on the same day that many students took their FCAT exams.

Three 14-year-old students and a 13-year-old from Pembroke Pines were recovering at Memorial Hospital West.

According to a father of one of the children, the students drank Redline Energy Drinks to help them be more alert for the FCAT.

The four male students in the eighth grade at Falcon Cove Middle School in Weston had to be rushed to the hospital.

"Increased heart rate, sweating, lightheadedness," said Broward County Sheriff's Fire Rescue representative Mike Jachles. "All four male students were transported to Memorial Regional Hospital."

A parent said he's upset that the drinks are available to young children.

"I'm very worried about that," said Harold Rivera.

Rivera said he was frightened to see his 14-year-old son in the emergency room, shaking with bloodshot eyes. He said he questioned his son on why he would take such a potent drink.

"He said, 'I want to clear my mind and energy on the test,'" Rivera said.

Rivera said his son could have died.

Redline is a heavily caffeinated drink that includes several warnings on the bottle, including, "Not Intended For Anyone Under The Age Of 18 Years."

Rivera said there should be stricter guidelines.

"Why sell that product? Why is it easy for that age of child to find that in the store?" he asked. "I told my son, 'Did you read that?' He said, 'No, I didn't read anything.'"

A representative for the Broward County School District said energy drinks aren't permitted on school grounds. He said the district is learning from lessons like this one.

All four children were expected to be OK and released from the hospital late Wednesday.
