Post-Tax Medical Insurance Premium paid for Medical Deductions

Hello, if we take an itemized deduction and if our total medical expenses exceed 7.5% of AGI, could we count the post-tax medical insurance premium paid for medical deductions? 

 

- My husband employer (small business) pays a portion of the medical insurance premium for us

- We are required to pay $1700/mo to cover the remaining premium which is deducted post tax dollars from his pay check

-  Whatever amount the employer pays or we pay don't show up anywhere on W2

 

Are we allowed to deduct the portion we pay for the medical insurance premium since it's post-tax dollars? 

 

Thank you.
