Not all drugs can be stored in the refrigerator. It is recommended that patients find out the drug instructions and store them in accordance with the storage conditions and temperature on the instructions. For example, “room temperature” means 1030 degrees Celsius; “cool dark place” means dark light and does not exceed 20 degrees Celsius; “cold place” means 2 degrees Celsius. Therefore, medicines that need to be stored at a low temperature in the summer (the temperature is between 20 degrees Celsius and 20 degrees Celsius) can be placed in the refrigerator’s refrigerated layer, but the temperature should be kept between 2 degrees Celsius and 8 degrees Celsius, such as live bacteriological agents, unopened insulin, and so on. But some easy to absorb moisture denaturation, the medicine that does not bear low temperature, should not put in the refrigerator, the following 4 kinds of medicine should pay particular attention to.
Common syrups such as cough syrup, low temperature storage will lead to a decrease in solubility, precipitation of sugar and drugs, such as precipitation, resulting in drug concentration changes, after taking will affect the efficacy, or even adverse reactions. Generally speaking, the best storage temperature of syrup is 1030 degrees Celsius, avoid direct sunlight, the shelf life is 1 month after opening the bottle.
Skin external ointment such as erythromycin ointment, Futalin ointment, dermatitis cream, nitroglycerin ointment, etc., should not be stored at low temperature. Too low temperature will lead to drug stratification and ointment itself chemical changes, affecting the concentration and efficacy. These drugs should be stored at room temperature to avoid direct sunlight.
Aerosols, aerosols such as salbutamol aerosol, budesonide nasal spray should not be stored at low temperature, otherwise easy to spray unobstructed, drug fog uneven. Because the low temperature can cause the pressure difference inside and outside the tank to become smaller, the ejector (the source of the injection power of the drug) is not fully gasified.
Fourth, some injections.
For example, insulin injection began to use, should not be placed in the refrigerator. If it is repeatedly placed in a hot and cold environment, it will inhale air to form bubbles, resulting in inaccurate injection volume and more easily invalidated. And cold storage of insulin, if not restored to room temperature before injection, will cause pain, will also increase the stimulation of subcutaneous tissue. Kaifeng insulin, including bottled insulin, in no more than 30 degrees Celsius, cool room temperature environment can be stored for about 1 month.
It should also be noted that summer is a period of high incidence of drug deterioration. Before you take the medicine, we should keep an eye on whether the drug changes in its properties, such as vitamin E gel pills, cod liver oil and other capsule or pill formulations. If heated, there will be softening, rupture, oil spills, or even the whole bottle of medicine stuck together, the smell. This time should discard, do not continue to take.
