If you or one of your dependents has celiac disease and you itemize your deductions, the extra costs due to gluten-free dietary restrictions may be taken as a medical expense.

Gluten-Free Food and Travel Expense

You may deduct the cost of Gluten-Free (GF) food that is in EXCESS of the cost of the gluten containing food that you are replacing. For example, if a loaf of gluten-free bread costs $5.00 and a comparable loaf of gluten containing bread costs $2.50, you may include in your medical expenses the excess cost of $2.50.
