Pharmacists (PharmD) serve as the medication experts who counsel patients on their medication use, monitor patient health and progress, and provide recommendations for optimal medication regimens to prescribers. They require a broad knowledge of the manufacture and distribution of drugs; their composition, uses, strengths, doses, side effects, interactions and potential harmful qualities. Pharmacists work in a wide variety of practice settings, such as hospitals, clinics, community pharmacies, telehealth or tele-pharmacies, government facilities, universities, or drug companies.
