A pharmacist is a healthcare professional trained in the science and practice of medicines, including their preparation, dispensing, appropriate use, safety, and effects on the human body.
Pharmacists help ensure that medicines are supplied and used appropriately. Their responsibilities may include checking prescriptions, identifying potential drug interactions, advising patients on how to take medicines, explaining side effects and precautions, supporting medication adherence, and identifying problems that require review by a prescriber.
Depending on their training, workplace, and local regulations, pharmacists may also provide vaccinations, conduct certain health screenings, manage selected minor conditions, support chronic disease care, participate in clinical medication reviews, and contribute to public health programs. Pharmacists work in community pharmacies, hospitals, clinics, pharmaceutical manufacturing, research, regulatory agencies, academia, and other healthcare settings.
Pharmacists play an important role in medication safety because they can help identify inappropriate doses, duplicate treatments, contraindications, and interactions between medicines or between medicines and other substances. They can also help patients distinguish generic medicines from brand-name products and understand instructions for safe storage and use.
The scope of a pharmacist’s professional responsibilities varies by country and practice setting. Pharmacists do not automatically have the same prescribing authority or responsibilities as physicians; any prescribing or other expanded clinical duties depend on applicable laws, regulations, and professional qualifications.
QUICK FACT
A pharmacist’s role extends beyond dispensing medicines. Pharmacists also help prevent medication errors, monitor medicine safety, educate patients, and support the appropriate use of treatments.
