Colds are caused by viral infections, often with fever, nasal congestion, runny nose, cough, headache, and in some cases, loss of appetite and diarrhea. It is accompanied by pharyngeal congestion and enlarged tonsils. If you can pay attention to rest, hydration, symptomatic treatment, careful care, prevention of complications, and reasonable use of drugs, although the fever is high, usually 1-2 days, at most 3-5 days can be reduced, the course of the disease 5-10 days, nasal congestion and cough will also be cured. Some common anti-cold medicines are safe for adults, but children may have unexpected side effects even if they take them in the prescribed doses, and sometimes even more serious drug reactions occur. This is due to the fact that children’s body tissues and organs are not yet mature, and the function of each organ is not perfect, so they are sensitive to drugs. Therefore, I often warn parents of children with colds, antipyretic drugs we advocate the cautious use of new non-steroidal anti-inflammatory drugs, such as ibuprofen (Merlin, Toon, TenCen, Fenbuterol), naproxen. And non-steroidal anti-inflammatory drugs Nimesulide (Riziqing) can continue to reduce high fever for 8-12 hours, easy to sweat a lot to deficiency, etc. The following common cold medicines should be used with caution or should not be used. 1, aspirin (alias: acetylsalicylic acid, vinblastine, bamir, vinopirin, heart wet forest, Axiom, Asin, Stella, Lixin, Dongqing, etc.). Taking this drug is more prone to gastrointestinal reactions, which can easily produce side effects such as peptic ulcers, perforation, and upper gastrointestinal bleeding. If aspirin is used for a long time, it may also lead to weight loss in pediatric patients, intracranial hemorrhage and damage to the liver. In addition, because aspirin can inhibit cyclooxygenase, it can produce leukotrienes, a slow-reacting substance that can cause strong and long-lasting contraction of bronchial smooth muscle, resulting in severe asthma. 2.Anti-inflammatory pain (alias: indomethacin, Addidas, sports Pais, Dixie, Kubosin, Medaxin, Istin, etc.). The drug has the advantage of rapid anti-inflammatory and pain relief. However, its use in children leads to a high rate of adverse reactions. For example, there are common gastrointestinal reactions, which in severe cases can lead to inflammation of the digestive tract, allergic reactions, nausea, severe headache, mental confusion, depression, etc. In addition, anti-inflammatory pain can also damage the pediatric hematopoietic system, and aplastic anemia (leukemia) can occur in severe cases. 3.POTAXONE (alias: Butazolidone, Butazolidine, Phenylbutazolidine, etc.). It is an old drug for analgesia, antipyretic and anti-inflammatory, which may produce strong toxic side effects when taken by children. These adverse consequences include: cause nausea, vomiting, abdominal pain, constipation, etc.; inhibit hematopoietic function, causing aplastic anemia in serious cases; damage to the liver and cause jaundice and acute hepatitis; some children taking the drug may also cause swelling of the parotid gland, sublingual glands and other glands, inflammation, etc. 4, similar to “cold pass” class. Is a compound agent, the main ingredients contain: diclofenac (alias: diclofenac, diclofenac, diclofenac, diclofenac, norfendine, difen, fendi, fendienin, orfen, non-inflammatory, futalin, diagen, difenac, eko, intracellular and paracetamol, etc.), artificial oxaliplatin and paracetamol, etc., about children taking cold pass has led to many reports of hematuria. The drug is not only prone to gastrointestinal adverse reactions in children, such as diarrhea, stomach Yuk, nausea, etc., but also dizziness, headache and skin rash and other symptoms. Excessive or prolonged use may also cause pediatric hematopoietic dysfunction, and even lead to leukemia, and damage to liver and kidney function. 5, similar to “quick-acting cold capsules” class. The drug is also a compound, the main ingredients contain: acetaminophen (alias paracetamol, Tylenol, Tylenol, acetaminophen, Snapple-FR, Bilettone, Benadryl, Acetaminophen, Ariel Star, Aysen, An heating, a grain of essence, Danin, Jingdi, Dianda, Yasda, Yili less, etc.), caffeine and artificial oxymoron, etc.. Acetaminophen compounds can cause nausea, vomiting, sweating, abdominal pain and other gastrointestinal disorders, and in children with poor tolerance to the drug can also cause liver damage and even coma. Some doctors recommend that children under 3 years of age and newborns generally avoid the use of the drug because of incomplete development of liver and kidney function. In addition, common cold medicines such as compound cold punch, cold spirit tablets in the main ingredients also contain acetaminophen, children should also be used with caution. In particular, it should be noted that the cold is caused by an infected virus, and antibiotics are not effective against viruses. Doctors treat with antibiotics, mainly to avoid concurrent bacterial infections, and now many medical units advocate playing suspension (intravenous drip) plus dexamethasone to accelerate the reduction of fever (so-called humane), but soon the temperature will rise again, sometimes 2-3 days to reduce the fever of the cold, but with hormones 4-5 days can not get better, this is because hormones can suppress immunity, delaying the production of antibodies, and make the course of the disease dragged.
