Pharmacists are the people to go to whenever you need medicine! They advise doctors and patients on the medications needed and are responsible for knowing the effects of the medication, including any adverse side effects. They can also tell you what dosage to take and how different medications interact with each other if you need more than one medication. Many pharmacists work in community pharmacies, like drugstores, or health care centers, such as hospitals. Pharmacists are required to earn a Doctorate of Pharmacy and pass licensing exams.
