At the Chemist's
Chemists' shops are specialized shops where medicines are sold. Chemists' shops are usually situated on the ground floor. They have a hall for visitors, two departments for selling drugs, and proper working rooms.
The department for reception of prescriptions and delivery of drugs is called a prescription department. The other one is called a chemist's department. In the prescription department medicines are sold or made up according to prescriptions. In the chemist's department you can buy medicines without prescriptions.
The working rooms of a chemist's include rooms for washing, drying and sterilization of glassware, an analytical laboratory, a room for storing medicines, a room for dispensing them and some others.
At the chemist's all medicines are kept in drug cabinets, on open shelves and in the refrigerator. Poisonous drugs are kept in a drug cabinet with the letter A. Strong effective drugs are kept in a drug cabinet having the letter B.
The drugs prepared at the chemist's for immediate use should be kept in the refrigerator. Powders, galenical preparations and medicines produced at pharmaceutical plants are usually kept on shelves protected from light at a constant temperature, not higher than room temperature.
Every small bottle or box has a label with the name of the medicine. There are labels of four colors for the drugs prepared at the chemist's: labels of green color indicate medicines for internal use; blue labels indicate drugs used for injections. Drugs for external application have labels of yellow color. Drugs used for treatment of eye diseases have labels of pink color.
The single dose and the total dosage are indicated on the label or signature. The directions for ding administration are very important for sick people as well as for those who take care for them.
In the chemist's department medicines are kept according to the therapeutic effect: drugs for cough, cardiac medicines, drugs for headache. Disinfectants, herbs and things for medical care such as hot-water bottles, medicine droppers, cups, thermometers, etc. are kept separately.
There is also a pharmacist who is in charge of the supply of necessary medicines.
