How to judge the appearance of the drug has expired? Experts introduced, look at the color of the tablet, such as white tablets turn yellow, black, red or mildew, spots, have shown deterioration, can not be served.
In the hot summer days, everyone has to cool off the heat, but don't forget to give medicines at home to avoid summer heat. Experts remind that in summer, the temperature is high, the light is strong, the medicine is easy to deteriorate, and the medicines in the house need to be properly refrigerated.
On July 10, the reporter visited the city of Aksu and learned that most citizens do not know that medicines in hot weather also need to “stay off the heatâ€. In this regard, Li Feng, head of the Drug and Medical Device Supervision Section of the Regional Food and Drug Administration, said that the method of preservation of drugs will directly affect the efficacy of the drug. For every 10 °C increase in temperature, the chemical reaction rate of the drug is accelerated by 2-4 times. In high-temperature environments, some drugs that could have been stored for 3 years are likely to fail prematurely.
It is best to keep the medicine in its original packaging, so that it is easy to grasp the method and dosage. For unopened or single-dose independent inner packaging drugs, they should be stored according to the storage conditions specified in the drug label. The storage period before opening can be up to the expiration date of the drug label, and any medicine should be taken as soon as possible after opening. The shelf life will be shortened, even if it is not until the shelf life, it is best not to take it. Capsules, dropping pills and other drugs are easy to absorb moisture, and should be taken within 3 months to 6 months after opening. Taking the potion should be taken during the course of treatment.
Drugs often fail due to external conditions such as light, heat, moisture, air, temperature, and microorganisms. Different medicines have different storage conditions, but they are protected from light, dry, cool, and sealed. They are the four major factors for preserving medicines. The public must operate according to the specific storage requirements of medicines. Taking temperature as an example, some pharmaceutical packagings are marked as “storage at normal temperatureâ€, meaning that they are stored in an environment of 0°C—30°C; some medicines are marked on “packed in a cool and dry place†and should be stored at 0°C— 20 ° C dry place; other drugs are directly marked "2 ° C - 8 ° C refrigeration", it means to be stored in the refrigerator.
How to judge the appearance of the drug has failed? Li Feng introduced, look at the color of the tablet, such as white tablets turn yellow, black, red or mildew, spots, have shown deterioration, can not be served. Inhibition of granules and syrups often results in fermented taste, and some are also mildew. Injectables without an effective date will generally be yellow or darker in color, some will become turbid, and some will grow in flocculation. Sugar-coated tablets fail, often bursting, plaques or spots, autolysis, blackening, and mildew. When the ointment fails, the hydration phenomenon of the ointment occurs, or it becomes thin, discolored, odorous, and the gas in the ointment fills and the tube expands. Powder medicines are ineffective, generally have discoloration or agglomeration, and have a musty taste. The powder for injection can be seen to have a yellowish color after dissolution.
"Everyone should check the validity period of the medicines in the family medicine box every 3 months so as not to accidentally take expired medicines. Do not throw out expired medicines as garbage, and must be officially recycled and destroyed by the relevant departments to avoid being used by people or ' Recycling 'made new drugs for sale.'" Li Feng said.
