Drug utilization review.

Why are my prescriptions reviewed? Medco checks your prescriptions for potential safety issues, such as drug interactions and allergic reactions. This feature of your prescription drug benefit enables Medco and A&M Care to help prevent adverse reactions and improve the quality of your healthcare. This feature is especially important for people taking multiple medications who should be aware that certain medications—whether prescription or over-the-counter—can cause negative side effects when taken in combination. This happens once Medco receives your prescription information, whether you have your prescription filled through the mail order Medco Pharmacy ® or at a participating retail pharmacy.
