Nonprescription drugs and the elderly.

The trend toward self-care is increasing among elderly patients. Over-the-counter medications contribute to the well-being of older patients, but adverse effects may occur, including interactions with prescription drugs. Nondrug health care products and agents for external use are also helpful when properly used. Dry skin, dry eyes, arthritis, pain and gastrointestinal complaints are among the major indications for the use of nonprescription medications.
