They include the costs of equipment, supplies, prescription drugs and diagnostic devices needed for these purposes. Also included is needed travel costs. They include the costs of insurance and deductibles paid by the taxpayer that pays for medical expenses.

It depends. Medical and dental expenses can be deducted if the taxpayer itemizes deductions, and the total amount is over 7.5% of the taxpayers Adjusted Gross Income (AGI). If the adult diapers (incontinence supplies) were purchased to alleviate or prevent a physical or mental disability or illness the expense is deductible. You may want to get a note from the doctor with the diagnosis and statement that the adult diapers are medically necessary to keep with your tax records if the IRS questions the expense.
