Dr. Guo Xiheng
There is a significant distinction between prescription drugs and over-the-counter (OTC) drugs. Prescription drugs—medications with specific therapeutic effects and potential risks—may only be purchased and used upon presentation of a prescription issued by a qualified physician. These drugs are typically indicated for serious illnesses or conditions requiring precise dosage control and carefully tailored administration regimens; they tend to have potent pharmacological effects but may carry a relatively higher risk of adverse reactions. In contrast, OTC drugs have undergone extensive, long-term evaluation and are characterized by well-established efficacy and a low incidence of side effects. They can be purchased without a prescription and are intended for the management of mild conditions and routine health maintenance, offering greater convenience and safety in use. Furthermore, prescription drugs are subject to stricter regulations regarding advertising and distribution to ensure patient safety.
