What does SOS mean in medicine?
In medicine, SOS generally refers to a one-time medical order for medication, meaning the drug should be used only when necessary, and this order is valid within 12 hours.

A one-time medical order for medication is a prescription method given by a doctor, especially in emergency or temporary situations. If the medication is administered within 12 hours, the administration time must be recorded on the medical order sheet; if the medication is not used within 12 hours, the doctor must issue a new order. In medical prescriptions, SOS means "when necessary," typically used as a special instruction for drug use, indicating that a single dose may be temporarily given when the patient's condition requires it. The dosing interval is usually not fixed, aiming to flexibly administer medication according to the patient’s actual condition to better relieve symptoms or manage sudden situations.
In daily life, it is important to develop good living habits, avoid excessive fatigue, and refrain from intense physical activity to prevent bodily discomfort. It is recommended to engage in appropriate exercises such as walking or jogging based on individual conditions, which can help enhance physical immunity and support recovery.
