Pharmacists are health professionals responsible for the dispensation of prescription and nonprescription medications. They act as consultants to health practitioners and the general public concerning possible adverse drug reactions and interactions, and may also give advice relating to home medical supplies and durable health care equipment. The role of the pharmacist has evolved into that of consultant and medicinal expert, because of the expanded duties of pharmacy technicians and the increasing time restrictions placed on health maintenance organization physicians.
The most common pharmacist positions are that of a community pharmacist or retail pharmacist. A community pharmacist works behind the counter at a pharmacy such as Wal-Mart, CVS, or Walgreens, along with pharmacy technicians. A pharmacist can also work as a hospital pharmacist where they instruct and counsel patients on the proper use and adverse effects of medically prescribed drugs and medicines. There are more than 287,420 pharmacists practicing in the United States.
