The nurse practitioner's (NP's) role in providing quality care continues to evolve, concurrent with the ever-evolving health care system. With an influx of uninsured and underinsured patients, NPs must not only provide high-quality health care, they must also address cost-efficient treatment options for patients who cannot afford expensive medications. Familiarity with the cost of medications and prescribing cost-efficient medications are valuable tools NPs can use to encourage patient compliance with a specific care regimen, consequently improving the overall health of uninsured or underinsured individuals. Knowledge of patient assistance programs may also assist NPs in decreasing prescription drug costs for patients. Cost-efficient treatment options for upper respiratory infection, migraine headache, eczema, trichomoniasis, and polycystic ovarian syndrome are presented.
