Like your doctor, your pharmacist plays an important role in helping you maintain your well-being. When you choose a Mercy pharmacy, you’ll have a pharmacist who is uniquely qualified to assist you not only with routine prescriptions, but with hard-to-find, hard-to-fill ones, as well.

Mercy pharmacists are specially trained and licensed to formulate compounded medications – prescriptions that are prepared exclusively for an individual patient’s needs.

Compounded medications may be necessary when:

  • A particular medication is no longer available from the manufacturer
  • A patient is allergic to certain ingredients in commercially prepared medications
  • A tailored dosage is required
  • A combined formula is desired to reduce the number of medications taken by a patient
  • An alternate form of the medication makes it easier for the patient to use (e.g., liquid instead of pills)

In addition to compounded medications, our pharmacies offer:

  • Infertility medications
  • Flu shots/flu mist
  • Injectable medications
  • Same-day service
  • Home delivery by mail or UPS

Vaccination hours are 9:30 a.m. to 4:30 p.m. Monday through Friday.

The Mercy Pharmacy is located in Suite 140 of the Clayton-Clarkson Building, near the East Entrance.
