The pharmacy provides consumers with prescription drugs and medications, as well as generic and discount drugs, over the counter (OTC) medications, and sundries. They are found in retail locations as well as within hospitals and clinics. A pharmacy may offer express service or have 24-hour locations, and may also offer discounts, online services, prescription fulfillment and vaccination services. Pharmacies also educate patients about medications and their uses and side effects, including drug interactions and allergic reactions.
A pharmacy provides employment for licensed pharmacists as well as pharmacy technicians. Nowadays they rely on computerized record-keeping as well as systems that work to reduce the possibility of over-prescription and adverse reactions in patients who take multiple medications. Pharmacists also work with local health authorities to reduce the possibility of prescription fraud and other public health issues.
