After the doctor makes a prescription, the pharmacist needs to prepare the preparation according to the doctor's advice on the prescription and choose the administration method according to the doctor's requirements. Among them, PO and SOS are two common ways of administration, which mean oral administration and first aid respectively.
PO is the abbreviation of Latin per os, which means oral administration. It is very common in routine drug treatment. For example, the drug dosage is "65438+ 2 tablets a day", that is, "PO qd 2 tablets". SOS is the abbreviation of Latin Siopusit, which means the way of administration when necessary, and is often used in emergency medical applications, such as the use of some analgesic drugs. On the prescription, the doctor will indicate the dosage and mode of administration, such as "painkiller PO, 1 time a day, SOS".
Other modes of administration:
Besides oral administration and first aid, there are other ways of administration, such as intramuscular injection, intravenous injection and transdermal patch. These different ways of administration have their own characteristics and scope of application, and doctors will choose the appropriate way of administration according to the patient's situation and needs.
In addition to the mode of administration, the doctor's advice also includes the description of dosage, frequency and time of administration. In the process of drug treatment, pharmacists need to carefully read the doctor's advice, accurately allocate drugs, and monitor and adjust according to the patient's condition and drug treatment response to ensure the safety and effectiveness of drug treatment. At the same time, patients also need to follow the doctor's advice, take medicine on time and in quantity, and inform the doctor in time of any discomfort and adverse reactions.
