Drugs can prevent and treat diseases and restore and protect health. However, drugs are toxic in three aspects, and any drug has different degrees of toxic and side effects. Therefore, drugs can save lives and protect health as long as they are properly managed and used.

Prescription drugs refer to drugs that can only be prepared, purchased and used by doctors. The indications of prescription drugs are mostly complex and severe, so it is difficult for patients to judge and treat themselves with drugs.

Over-the-counter drugs are all from prescription drugs, which are generally drugs with long-term use, definite curative effect, convenient administration, stable quality and safe use by non-medical professionals. Over-the-counter drugs were called "over-the-counter drugs (OTC)" in the United States, and later became a common name all over the world.

Pay attention to buying medicine at the drugstore.

1, you must go to a legal pharmacy to buy medicine. Legal pharmacies are approved by the drug supervision and administration department (market supervision and administration department), and pharmacies hang the Drug Business License and Business License.

If you know what medicine to buy, you can directly tell the name of the medicine. If you don't know what medicine to buy, please explain to the licensed pharmacist in the store the purpose of buying medicine: whether it is for your own use, for children or the elderly, and what diseases to treat.

3. When buying prescription drugs, you can only buy and use them with a doctor's prescription. Without a doctor's prescription, pharmacies will not sell you prescription drugs at will for the safety of your medication.

4. When buying over-the-counter drugs, you should have a clear understanding of the patient's condition, such as what medicine you have used, how effective the drug is, and the history of allergies.

Before deciding to buy a certain medicine, you should read the instructions carefully to see if it has symptoms. If you don't know the contents of the instructions, you can consult a licensed pharmacist in the store to avoid buying or using the wrong medicine.

6. When buying drugs, be sure to carefully check the production date, expiration date and other contents on the drug packaging, and don't buy expired drugs.

7. Don't forget to keep shopping vouchers, such as shopping receipts or invoices. Once there is a drug quality problem, the shopping voucher is an important voucher for complaints, claims and safeguarding your rights and interests.
