How to store medicines correctly?

The storage of drugs directly affects their safety and effectiveness. The correct storage method needs to be based on the characteristics of the drug, environmental requirements and packaging instructions. The main contents include:Avoid light, moisture-proof, temperature control, classified storageAt the same time, attention should be paid to the refrigeration requirements for special drugs (such as insulin and biologics), as well as regular inspections of household medicines. The following will provide detailed step-by-step instructions to help you manage medicines scientifically.

It is recommended to use a sealed box and place a desiccant. It is best to choose an opaque material for the medicine box and place it in a cool and dry place.

2. Temperature control: distinguish between normal temperature and refrigerated medicines

Normal temperature medicines (10-30°C) account for the majority, but some require refrigeration (2-8°C), such as unopened insulin and certain antibiotic syrups. Note:Refrigeration ≠ Freeze, freezing will cause denaturation of protein drugs. In addition, when the temperature is high in summer, ice packs can be used temporarily to store medicines that need to be refrigerated, but avoid repeated alternations of hot and cold. Temperature requirements are usually marked on the drug package insert, so be sure to read them carefully.

After opening, eye drops, oral liquids, etc., even if they have not expired, are recommended to be used within one month because the effectiveness of the preservatives may be reduced.
