Mylan, a pharmaceutical company, cut the price of EpiPens from $600 to $300. However, the company says only some may use the $300 savings card.
Tucson Unified School District says it is doing everything to protect their students from getting an allergic reaction.
Rincon High School's nurse said she has noticed parents turning to the schools to get their kids an EpiPen.
"A lot more parents have called and asked if we have one on stock because they don't have one at home at this time," said Monica Ibarra. "They are counting and relying on our EpiPen for their child."
She said most parents say their child isn't able to have one with them because either it has expired or they can't afford to purchase a new one.
There were nine cases in the school district last year.
The nurse advises that if a parent knows their child has a known allergy, that they notify their school's health office.
