Text C. At a Chemist’s¹
As you know on receiving a prescription from a doctor or on following a home treatment all of us need medicines which are ordered or bought at a chemist’s.
There are usually two departments in a large chemist’s. At the chemist’s department² one can have the medicine immediately, other drugs have to be ordered at the prescription department.³
At any chemist’s all the drugs are kept in drug cabinets. Every small bottle (бутылка), a tube or a box of medicine has a label on it. White labels indicate drugs for internal use, yellow ones indicate drugs for external use and blue ones indicate drugs used for injections. The dose to be Jaken and the directions for the administration are also indicated on a label. Indicating the dose and the name of any medicine is necessary for chemists, nurses, doctors and patients themselves. It prevents confusing (to confuse— путать) different remedies, some of which are poisonous. Their overdosage may cause unfavourable reactions and sometimes even death.
At a chemist’s one can buy different drugs for intramuscular and intravenous injections, for oral administration and for external use.
Before using the medicine the patient must know well that he is taking the proper drug and in the necessary dosage.
