Pharmacists also provide information about drugs to patients and customers, answer questions about prescription and over-the-counter drug side effects and interactions, as well as monitor the patient’s progress to ensure the medications are effective. To work as a pharmacist, one must obtain a Doctor of Pharmacy degree, or Pharm. D.
