Pharmacists are healthcare professionals who specialize in the field of pharmacy, which involves the safe and effective use of medications. They work closely with patients and other healthcare providers to help ensure that medications are prescribed and dispensed correctly, monitor for potential drug interactions or adverse effects, and provide guidance on how to properly take medications. Pharmacists also play a key role in educating patients about their medications and helping them manage chronic conditions. Additionally, pharmacists may be involved in drug research, development, and testing.
