Bandages are deductible, they do not have to be prescribed by a doctor.
Some medications must be prescribed, because this is a regulatory requirement to prove the expense is medically necessary. For example, I have low vitamin D, so I have a prescription because it's medically necessary, but someone else taking vitamins for general health benefit would not qualify. Banadages don't have the same requirement, because caring for a wound is obviously something that affects the natural function of the body.
Medical expenses are the costs of diagnosis, cure, mitigation, treatment, or prevention of disease, and for the purpose of affecting any part or function of the body. These expenses include payments for legal medical services rendered by physicians, surgeons, dentists, and other medical practitioners. They include the costs of equipment, supplies, and diagnostic devices needed for these purposes.
Medical care expenses must be primarily to alleviate or prevent a physical or mental disability or illness. They don't include expenses that are merely beneficial to general health, such as vitamins or a vacation.
