The weather is getting colder and with the change in weather, the number of colds and flu has skyrocketed. In many schools now, close to 1/5 of the children are off work because of colds. And colds in adults are just as bad. Symptoms after a cold are usually unbearable, nasal congestion, runny nose, sore throat, low-grade fever …… At this time, many of my friends take anti-inflammatory drugs (antimicrobials), what cephalosporin, levofloxacin, azithromycin. In the end, the cold should not eat anti-inflammatory drugs, when to eat it? Most colds are “common colds”, which are mostly caused by viral infections, including rhinovirus, adenovirus, coxsackie virus, etc. The common cold is called “spontaneous cold”. The common cold is known as a “self-limiting disease”, which means that the disease can gradually improve to a certain extent and recover slowly until it is cured. According to the course of the disease, a common cold without complications usually resolves in 5 to 7 days and does not require much medication. In addition, some so-called antiviral drugs do not have a definite effect, so antiviral drug treatment is generally not necessary. For the common cold clinical to symptomatic treatment, relief of cold symptoms, and patients are instructed to try to strengthen the rest, appropriate hydration, maintain indoor air circulation, to avoid secondary bacterial infection. When should I take anti-inflammatory drugs? Antibacterial medication should be added when there is a clear combination of bacterial infection, such as when bronchitis, pneumonia, sinusitis or otitis media are considered. Such patients often have symptoms such as coughing, coughing up yellow sputum, retaining yellow snot, and pain in the ear canal, which are often combined with an elevated body temperature, and some patients may have a high fever. Such patients are advised to go to the hospital to do a routine blood test, if it is clear by the elevation of white blood cells, neutrophils, identified as a bacterial infection, must be added as soon as possible antibiotics to control the inflammation. Since we do not allow patients with colds to take anti-inflammatory drugs casually, but there are very uncomfortable, very difficult to do? Some non-anti-inflammatory drugs are helpful in relieving symptoms. For example, antipyretic and analgesic medications are effective mainly for fever, sore throat and generalized aches and pains in patients with the common cold. These include acetaminophen (paracetamol), aspirin, ibuprofen and diclofenac. For patients with nasal congestion, pseudoephedrine and ephedrine-based medications can be used to relieve symptoms such as nasal congestion, runny nose, and sneezing. Active ingredients include. Antihistamine drugs such as paracetamol have a similar effect, but can cause drowsiness after taking them. For patients with cough and phlegm, proper expectoration and cough suppression are also appropriate treatments to alleviate symptoms. The above drugs have their own indications and contraindications, for children, elderly patients and patients with combined cardiovascular and cerebrovascular diseases, peptic ulcer, etc., must consult a doctor before taking the drug, to avoid the harm caused by the side effects of the drug. However, we should pay attention to an extremely critical type of cold: influenza. This cold has a rapid onset, with high fever, generalized pain, significant malaise and mild respiratory symptoms, and the complications and deaths it causes are very serious. The disease is caused by influenza viruses, which can be categorized into three types: A (A), B (B), and C (C). Type A viruses often undergo antigenic mutation, are highly contagious, spread rapidly, and are highly susceptible to widespread pandemics. Type A H1N1 is also a type A one. The disease is self-limiting, but in infants and young children, the elderly and patients with underlying cardiopulmonary diseases are prone to complications such as pneumonia and other serious complications leading to death. For high-risk groups, on the one hand, it is recommended to get a flu shot in the fall, on the one hand, the emergence of severe cold symptoms, do not hold out at home, obsessed with eating anti-inflammatory drugs, hurry to the hospital, early treatment may reduce the risk of death.
