Which Medicines Are Suitable For The Refrigerator, And Which Are Not Suitable?

Sep 27, 2022

Medicines are special commodities and have strict temperature requirements. If they are not stored at the specified temperature, the medicines are likely to deteriorate. In particular, biological products that need to be refrigerated, such as insulin, vaccines, immune serum, blood products, etc., if they are not stored at the specified temperature, the drugs may be completely ineffective, which will not only fail to prevent and treat, but also delay the patient's condition.


Medicines suitable for storage in the refrigerator


External medicines: such as eye drops, nasal drops, ear drops, lotions and mouthwashes, etc., it is best to keep them in the refrigerator in summer to prevent the liquid from deteriorating at high temperature.


Injections, some capsules: Some injections such as insulin, and live bacteria preparations such as Lactase, Mummy Ai, and Livzon Changle usually need to be stored in the refrigerator at 2-8 degrees Celsius to avoid heat and sunlight. However, the opened insulin can be stored at room temperature below 25 degrees Celsius.


Suppository: This type of medicine, such as vaginal embolism medicine for women, will soften due to high temperature, which is inconvenient to use. It can be placed in the refrigerator in summer, or put in the refrigerator before use, and it can be taken out after the medicine has hardened before use.


Medicines that should not be stored in the refrigerator


Liquid preparations: such as cough syrup, antipyretic and analgesic solution or cold syrup, etc. In most liquid preparations, the solubility of the drug will decrease when the temperature is too low, and the sugar in the syrup is also prone to crystallize, resulting in a drug concentration that does not match the original label. Therefore, these syrup preparations are generally not stored in the refrigerator after opening, and are mostly stored at room temperature.


Powder: A medicine mainly used by children. Most of these medicines are sub-packaged and sealed by the machine with moisture-proof wax paper. Since many additives in the powder to improve the taste can promote deterioration, the powder can only be stored for up to 3-5 days after opening.


Tablets and capsules: These medicines are generally afraid of moisture, so there is often a desiccant in the package. Do not throw it away after opening the package. After taking the medicine, the desiccant should be placed in the original bottle. Bulk tablets or capsules should be stored in light-proof glass or plastic bottles, preferably with desiccant, and different medicines should be stored separately to avoid mixed flavors and affect the curative effect.
