Medicine storage in summer

Expired drugs can cause poisoning. The sun can accelerate drug metamorphism.
Storage temperature of medicines is generally divided into three categories which will be indicated in the instructions. Insulin, albumin, gamma globulin, BCG, thrombin and other biological products are commonly stored under the temperature of 2 ~ 8 ℃; The medicines with their instruction indicating "store in cool places" must be under 22 ℃; The ones with no particular indications requiring storage under special conditions should generally be kept under less than 30 ℃. Sunshine also can affect the stability of the drug, fasten the movement of drug molecules and accelerate drug reaction. Under the environment of high temperature, some drugs which can be stored for three years can expire in advance, go bad or cause toxic reactions.

In addition to western medicine, some Chinese herbs are also kept in the medicine cabinet. Due to high temperature and high humidity, there can be mildew and moths especially in creams and pills as they mostly have been added honey.

We should pay special attention to the following points:

1. In general, medicinal materials are best put in the refrigerator for storage, especially precious medicinal materials like bird's nest to avoid insects and moist.

2. Moth and mildew prevention
Put some medicinal materials with strong smell such as pepper, star anise, cinnamon, etc with together with the medicine can be mothproof and mouldproof.

3. Moisture prevention
Some herbs are dried first before they are sealed and stored. But herbs such as astragali, dried tangerine or orange peel, angelica, yam should not be exposed much in the sun. You can "baked" them dry before you store them. Dried tangerine or orange peels and angelica can lose the herbal smell if being exposed to the sunlights. They are better stored in the refrigerator.
