Most medicines are required to be stored in a cool place at room temperature. When the temperature does not exceed 30 degrees Celsius, special treatment is generally not required. For example, if the temperature is too high, some medicines, such as suppositories, should be stored in a refrigerated freezer. Many people know that medicine is afraid of high temperature, but did you know that some medicines are also afraid of cold? Medicines that are susceptible to moisture, such as dry yeast, compound licorice tablets, etc., should be stored in a closed container to avoid moisture at low temperatures.
Medicines that should be kept in the refrigerator
Insulin, mainly used by diabetic patients, should usually be kept in a refrigerator to avoid heat, sunlight or freezing. If the patient goes out, it can be stored at room temperature below 25°C for approximately 6 weeks.
Liniment usually contains volatile solvents such as alcohol, etc. After use, the bottle cap should be tightened and placed in a refrigerator for a longer shelf life.
3. Topical drugs
External medicines such as eye drops, nose drops, ear drops, lotions and mouthwashes are best placed in a refrigerator in the summer.
Most antibiotic syrups are in the form of suspensions that need to be brewed. The shelf life of these powdered medicines in a container in an uninfused state at room temperature is the marked expiration date. Once water is added, its shelf life has been shortened, generally no more than 15 days, and it should be placed in a refrigerator for refrigeration.
The suppository may soften due to the high temperature and is inconvenient to use. It can be placed in a refrigerated cabinet in summer, or placed in a refrigerated cabinet before use, and taken out after hardening.
Medicines that should not be kept in the refrigerator
1. Tablets and capsules
After opening the package, do not throw away the attached desiccant randomly. After taking the medicine, place the desiccant in the original packaging bottle, especially for sugar-coated tablets. If the tablets or capsules are in bulk, they can be stored in light-proof glass or plastic bottles. It is best to put a desiccant inside. Note that different medicines must be stored separately.
Mainly medicines used by children. Most of these medicines are packaged and sealed by machine with moisture-proof wax paper. Since many additives to improve the taste in the powder can promote deterioration, the powder can only be stored for at most 3 to 5 days after opening.
3. Liquid preparation
Generally refers to cough syrup, anti-allergic syrup, antipyretic analgesic solution or cold syrup, etc. These syrup preparations generally do not need to be placed in a refrigerator after opening the bottle, as long as they are stored at room temperature. Most liquid preparations may reduce the solubility of the drug at too low temperature, and the sugar in the syrup is also easy to crystallize, causing the concentration of the drug to be inconsistent with the original label.
Too low storage temperature of topical cream can cause matrix delamination, which affects the uniformity and efficacy of the ointment. Therefore, the ointment should not be stored in the freezer and stored at room temperature.
