Pharmacy also called "drugstore" is a retail shop which provides prescription drugs, among other products. At the pharmacy, a pharmacist oversees the fulfillment of medical prescriptions and is available to give advice on their offerings of over-the-counter drugs. But pharmacy is not just about filling prescriptions. It is also about promoting health awareness and contributing to the betterment of the community. Pharmacists may:
  • Prepare or supervise the dispensing of medicines, ointments and tablets.
  • Advise patients on how their medicines are to be taken or used in the safest and most effective way in the treatment of common ailments.
  • Select, give advice on and supply non-prescription medicine, sickroom supplies and other products.
  • Develop legally recognised standards, and advise on government controls and regulations concerning the manufacture and supply of medicines.
  • Work in the research and development of medicines and other health-related products.
  • Be involved in the management of pharmaceutical companies.
  • Advise members of the public and other health professionals about medicines (both prescription and over-the-counter medicines), including appropriate selection, dosage and drug interactions, potential side effects and therapeutic effects.
