No. SECTION 125 is your employer's benefit plan. It is also known as a "cafeteria plan". Usually, what is reported there is your medical insurance premiums that are paid with pre-tax income. They are not taxed and are not included in your W-2 Box 1 wages so you can not deduct them as medical expenses.
Because the money used for this plan is not being taxed (pre-tax), then no deduction is allowed for the expense.
