I am informed by the Revenue Commissioners that tax relief for health expenses is governed by the provisions of section 469 of the Taxes Consolidation Act, 1997. Under section 469, tax relief may be claimed, subject to certain conditions, for "health expenses". Health expenses are defined as expenses in respect of the provision of health care, being expenses representing the cost of, among other things, "drugs or medicines supplied on the prescription of a practitioner". It is the view of the Revenue Commissioners that the cost of any medicines supplied on the prescription of a practitioner, i.e. a medical doctor or a dentist, qualifies for tax relief.
