A review of the mistakes in cold medication in winter
Mistake 1: taking cold medicine is easy to make trouble
Many people think that they want to go to sleep every time they take cold medicine, so that many drivers dare not take medicine even if they have a cold. In fact, it's just some ingredients that make people sleepy in cold medicine. Experts pointed out that what makes people sleepy in cold medicine is antihistamine, which is used to relieve the symptoms of stuffy nose, runny nose and sneeze. Therefore, when choosing cold medicine, drivers should pay special attention to whether it contains this ingredient.
Myth 2: addictive to cold medicine
Many people have such a worry: Taking ephedrine cold medicine will also be toxic or addictive? Experts pointed out that ephedrine is an alkaloid extracted from Ephedra, which has the functions of antitussive and antiasthmatic, dilating the trachea and relieving congestion of nasal mucosa. Although ephedra is the most important raw material for the synthesis of methamphetamine, it needs a series of chemical reactions to form from ephedrine to methamphetamine, so there is no need to worry about poisoning or addiction. In addition, the content of ephedrine in a single dose of drugs is very small. In adults, the oral dose is generally only 15-30 mg per time, and the maximum daily total dose is 150 mg. It is far from the dangerous dose of poisoning, and will not produce addiction and other side effects. However, experts also suggest that people with heart disease, high blood pressure, diabetes and renal insufficiency should be cautious with ephedrine drugs.
Mistake 3: only traditional Chinese medicine for cold
Many people think that the side effect of traditional Chinese medicine is small, so they have been taking traditional Chinese medicine for a cold. Experts said that from the pharmacological point of view, the use of traditional Chinese medicine in the early stage of the cold may have a better control effect on the cold virus, but in the case of severe cold symptoms, the use of traditional Chinese medicine is' too late ', because the effect of traditional Chinese medicine is long, at this time, it is better to choose the western medicine.
Error 4: the effect of compound medicine is better
When choosing cold medicine, many people think that the effect of compound cold medicine for multiple symptoms is better. Experts point out that taking compound cold medicine sometimes has a bad effect. Although the function of the compound preparation is multifaceted, but it is not without emphasis. Many cold medicines of the compound preparation are also different in the proportion of ingredients. Therefore, patients must choose the right medicine when purchasing the cold medicine.
Mistake 5: take cold medicine to prevent cold
Colds are caused by viruses, usually rhinoviruses and coronaviruses. Cold is the most common disease in life. It is normal for a person to catch a cold twice or six times a year. The cold here refers to the common cold, not the influenza. If you really get flu, you can't use your own medicine. You have to go to the hospital for regular treatment. Influenza can be prevented by vaccination, but there is no specific medicine for common cold, because there is no targeted 'anti cold drug'.
Myth 6: 'multi drug combination' has faster effect
Some people simply take several kinds of cold medicine together to get better. It seems that the more medicine they take, the faster they get better. Experts pointed out that cold medicines produced by different manufacturers may contain the same ingredients. If taken blindly at the same time, it is likely to cause an increase in dose, which is adverse to health. In addition, some people take only one cold medicine, but increase the dosage without authorization. Experts pointed out that taking cold medicine should be within the recommended dose range, the elderly and the weak had better start taking it from a small dose, and slowly increase the dose to avoid adverse reactions.
Mistake 7: take antibiotics as cold medicine
As mentioned earlier, common cold is caused by virus, with rhinovirus and coronavirus the most common. Antibiotics are ineffective in the treatment of virus, so it is ineffective to take antibiotics when you have a cold. Many years ago, doctors thought that the cold caused by virus often developed some bacterial infection complications, such as bacterial sinusitis. Later studies have shown that indiscriminate use of antibiotics for cold patients is of no benefit to the disease and can not prevent bacterial infection. In this way, antibiotics are abused. The bad effect is to produce strong bacteria resistant to antibiotics, which will lead to "incurable" infection in the future.
