[ China Pharmaceutical Network Health and Wellness ] In the summer, many patients will store the drugs in the refrigerator. So, is it better to store the drugs in the refrigerator in summer? Experts say that not all drugs can be placed in the refrigerator. For preservation, it is recommended that the patient find the drug instruction manual. In general, there are four types of drugs that are best not stored in the refrigerator.
In the summer, drugs that need to be stored at low temperature (between 2 and 20 degrees Celsius) can be placed in the refrigerator layer of the refrigerator, but the temperature should be controlled between 2 and 8 degrees Celsius, for example, live bacteria, unopened insulin, etc. However, some drugs that are hygroscopically degradable and not resistant to low temperatures should not be placed in the refrigerator.
Online said that drugs are afraid of heat, is it better to put drugs in the refrigerator in the summer?
Not all drugs can be stored in the refrigerator. It is recommended that patients find the drug instructions and save the drugs according to the storage conditions and temperature in the instructions. For example, "room temperature" means 10~30 degrees Celsius; "cool and dark place" means avoiding light. It does not exceed 20 degrees Celsius; "cold spot" means 2 to 8 degrees Celsius. Therefore, medicines that need to be stored at low temperatures in summer (temperature between 2 and 20 degrees Celsius) can be placed in the refrigerator layer of the refrigerator, but the temperature should be controlled between 2 and 8 degrees Celsius, for example, live bacteria, unopened insulin. Wait. However, some drugs that are hygroscopically degradable and not resistant to low temperatures should not be placed in the refrigerator. The following four types of drugs should be noted.
First, syrup. Common syrup drugs such as cough syrup, low temperature storage will cause decreased solubility, precipitation of sugar and drugs, etc., resulting in changes in drug concentration, will affect the efficacy after taking, and may even have adverse reactions. In general, the optimal storage temperature of syrup is 10~30 degrees Celsius, avoid direct sunlight, and the shelf life is 1 month after opening.
Second, ointment. External skin ointment such as erythromycin ointment, futalin ointment, dermatitis ointment, nitroglycerin ointment, etc., should not be stored at low temperature. If the temperature is too low, the stratification of the drug and the chemical change of the ointment solvent itself will affect the concentration and efficacy. These drugs should be stored at room temperature and protected from direct sunlight.
Third, the spray. Aerosols, sprays such as salbutamol aerosol, budesonide nasal spray, etc. should not be stored at low temperatures, otherwise it is prone to poor spray and uneven drug mist. Because the low temperature causes the pressure difference between the inside and outside of the tank to become small, the propellant (the source of the jet of the drug) is incompletely vaporized.
Fourth, some injections. For example, after the insulin injection is started, it 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 likely to fail. And refrigerated insulin, if injected before it returns to room temperature, causes pain and increases irritation to the subcutaneous tissue. Unsealed insulin, including bottled insulin, can be stored for about 1 month in a cool, room temperature environment of no more than 30 degrees Celsius.
It should also be noted that summer is the high incidence of drug deterioration. Before you take the medicine, you should keep your eyes on it and observe whether the drug has changed in properties such as vitamin E capsules, cod liver oil and other capsules or capsules. There will be softening, rupture, oil leakage, and even the whole bottle of medicine sticks together and odor occurs. It should be discarded at this time, do not continue to take it.
