Recently, a news report on "A woman infected with new crown taking medicine randomly caused liver failure" has caused widespread heated discussion.

According to media reports, a 40-year-old woman in Pingdingshan, Henan panic after being infected with the new coronavirus. She took medicine as soon as she developed fever. As a result, she did not follow the doctor's instructions to reduce the fever, resulting in yellow skin throughout her body and liver failure. She was urgently transferred to an ICU hospital in Zhengzhou for emergency treatment.

On November 16, Huashan Hospital Affiliated to Fudan University published a popular science article, which pointed out that many people have misunderstandings about cold medication use that cannot be ignored, and scientific medication guidance is urgently needed to help the public use reasonably. Home treatment, what are the precautions for using medicine? Focus on the key points↓↓↓

Looking at the basket of "cold medicines", how should I choose?

Cold medicine is a general term. For the sake of easy understanding, it is roughly divided into the following categories:

Know how many categories of cold medicines are divided into, so we "recisely" the ingredients in the instructions for common cold medicines:

. Cold medicine cannot eliminate virus

Cold medicine can only relieve various discomfort symptoms that occur when catching a cold, making people feel more comfortable, which is what we usually call "symptomatic treatment".

. If the symptoms are mild, you can avoid cold medicine

"It is better to take it than not to take it" is a misunderstanding of medication. In addition, regular medication is not required, only medications should be taken if necessary. For example, you do not need to take antipyretic drugs when there is no fever or low fever.

How many types of cold medicine should I take?

. When taking compound cold medicine and other drugs together, please pay attention to

Cold medicine has one or two prescriptions. Compound drugs usually include several types of "cold medicines". Therefore, do not reuse other similar drugs. Just take one of the same type of drugs.

For example, take the common cold drug "*NO" as an example, which already contains " acetaminophen , pseudoephedrine hydrochloride, dextromethorphan hydrobromide , and chlorphenamine maleate ". There are all drugs to reduce fever, relieve cough, and relieve nasal symptoms, but there are no phlegm-reducing drugs. If there is a need to reduce phlegm, it is enough to just add phlegm-reducing medicine.

. Do not take compound cold medicine containing antipyretic ingredients

For example, if you have nasal symptoms, you can choose cetirizine , loratadine or chlorphenamine maleate. Chlorphenamine maleate is the second choice, because Chlorphenamine is the older generation of anti-allergic drug , with relatively many side effects, which may not be suitable for some people. For example, if you cough and phlegm, you can use some cough and phlegm-relieving medicines alone.

Can traditional Chinese medicine and Western medicine be taken together?

. Don’t think it is a Chinese medicine, but it is not in conflict with Western medicine by default

Chinese medicine is usually a compound prescription. It should be noted that some Chinese medicine compound prescriptions also contain the antipyretic ingredients of Western medicine. For example, acetaminophen, such as Wei C Yinqiao Tablets, Yinju Jiedu Pills, Ganlang Ning Capsules, etc., all contain acetaminophen.

So, be sure to look at the medication ingredients in the instructions before taking it. Do not take it with Western medicine and antipyretic drugs.

. Traditional Chinese medicine is not "the more you will be better". Do not take many different ingredients or effects of taking

. Different Chinese medicines may also be repeated before taking

. Therefore, do not blindly think that taking more than one can have more anti-disease weapons. In fact, so many so-called weapons sometimes only bring more side effects, such as damaging the spleen and stomach, liver and kidneys, etc.

Drug reminder for various drugs

Acetaminophen

Overdose can cause serious liver damage to and even fatal.

On March 3, 2020, the State Administration of Drug Administration issued the "Announcement on Revision of the Instructions for the Sustainable and Sustained Release Preparations of Acetaminophen", which recommended that the maximum amount of acetaminophen oral treatment should not exceed 2 grams per day. If a normal person takes 6 to 10 grams at a time, it can cause large-scale liver tissue necrosis and even liver failure. Therefore, it should be taken strictly in accordance with the dosage and medication intervals in the instructions. Avoid pursuing the return to normal temperature, and taking medicine at a random short interval or increasing dosage.

Fever is the human body fighting against the virus. If the fever temperature in the general population does not exceed 38.5℃ and the body does not have any special discomfort, it is not recommended to take antipyretic drugs.

ibuprofen

A few patients will experience gastrointestinal discomfort when taking medicine. Patients with active or previous history of peptic ulcers, and are contraindicated for gastrointestinal bleeding or perforation.

Acetaminophen and ibuprofen

Do not take the two drugs at the same time, and can be taken alternately.

The two drugs have similar antipyretic effects, but a single dose of acetaminophen takes effect faster, while ibuprofen has a relatively strong antipyretic effect, and the cooling and maintenance time is relatively long.

Multiple compound cold medicines (including Chinese medicine compound prescriptions) contain acetaminophen, so special attention should be paid to this.

pseudoephedrine

s severe hypertensive , coronary heart disease is prohibited. Hyperthyroidism, diabetes , ischemic heart disease, glaucoma , and patients with prostate hypertrophy use cold medicines containing pseudoephedrine components with caution.

Chlorphenamine maleate

Use with caution for bladder neck obstruction, pyloric duodenal obstruction, hyperthyroidism, glaucoma, peptic ulcer, hypertension and prostate hypertrophy.

Dextromethorphan hydrobromide/forkide

For patients with excessive sputum, it is easy to cause sputum to fail to cough out, aggravate the infection, and in severe cases, suffocation may occur. Therefore, it is necessary to resolve phlegm first and do not just take antitussive drugs.
