Can Prescription Drugs Be Purchased at Pharmacies?

Prescription drugs are usually available in pharmacies, but they require a prescription from a hospital doctor for purchase. Generally, drugs can be divided into non-prescription drugs and prescription drugs. Non-prescription drugs are relatively safe, with proven efficacy and relatively small toxic and side effects. They do not require a doctor's prescription and have a clear "OTC" label on their packaging, allowing direct purchase in pharmacies. Prescription drugs, on the other hand, are medications that can be purchased, dispensed, and used with a prescription issued by a licensed medical doctor or assistant medical doctor. These drugs are typically used to treat chronic conditions such as hypertension, diabetes, etc. Prescription drug packaging will have a clear "Rx" label. To ensure the safety and effectiveness of prescription drug use, doctors must diagnose the condition, select the appropriate medication, and guide patients in their correct use. Therefore, prescription drugs must be dispensed, sold, purchased, and used based on a doctor's prescription, such as common antihypertensive drugs, hypoglycemic drugs, and injectable medications that require the use of a doctor or medical technician. In summary, prescription drugs are generally available in pharmacies, but a doctor's prescription from a hospital is required before purchase. It is important to note that both non-prescription and prescription drugs require careful reading of the indications, contraindications, and adverse reactions sections in the medication instructions. Patients should follow the dosage and instructions as prescribed by the doctor or the medication leaflet, and should not adjust the dosage without authorization to avoid affecting the efficacy of the medication.
