If you itemize your deductions on Form 1040, Schedule A, you may be able to deduct expenses you paid during the year for medical care (including dental) for yourself, your spouse, and your dependents. A deduction is allowed only for expenses paid for the prevention or alleviation of a physical or mental defect or illness. Medical care expenses include payments for the diagnosis, cure, mitigation, treatment, or prevention of disease, or treatment affecting any structure or function of the body. The cost of drugs is deductible only for drugs that require a prescription, except for insulin.
