Part of a pharmacist's job is to answer the questions of customers purchasing medications, according to KidsHealth. While pharmacists don't deal with medical diagnoses, they can answer questions about prescription and over-the-counter medications, including explaining side effects.
Pharmacists often have private areas available to talk to customers without being overheard, and some are also willing to answer questions over the phone, states KidsHealth. Pharmacists can answer questions regarding storage of medications, foods to avoid while taking certain medications, whether pills can be cut in half and precautions to take while using certain medications. They can also provide literature regarding specific medications.
