Antihistamines are currently the basic measure for the treatment of urticaria, especially chronic urticaria. The main antihistamines are H1 receptor antagonists and H2 receptor antagonists. Among the antihistamines, H1 receptor antagonists have strong antihistamine and anti-inflammatory mediator effects, so they will have a better therapeutic effect on all types of urticaria. With the rampant allergens in spring, the number of patients with urticaria increases. The small rash leaves patients with more than a sigh of relief, and the unbearable itchiness makes them look sad. In order to relieve the itchy symptoms, many patients can’t help but scratch with their hands, and some of them even apply ointment to the affected area without thinking. Blind self-governance of hives will not only not help relieve the itch, but may further aggravate the condition. It is best to seek the help of a medical professional for recurring hives. A. “Urticaria is life-threatening” is not an alarmist statement. Urticaria is an allergic skin disease, which is a limited edematous reaction to increased vasodilation and permeability of the skin mucosa. It is characterized by pruritic wind clusters, which disappear with the onset and leave no trace after fading. Some patients who have recurrent hives have palpitations when they mention it, while others think that hives can go away naturally anyway, so they don’t take it seriously. In fact, if you ignore the treatment of hives, the consequences can be very serious. It is not an exaggeration to say that hives are life-threatening when they are severe. As the disease progresses, the rash will spread throughout the body, and those with severe hives are often accompanied by symptoms of anaphylaxis such as panic, agitation, and a drop in blood pressure, which can be life-threatening. When the body rash is widespread, breathing difficulties, abdominal pain and other unusual symptoms should not be taken lightly, you need to go to the hospital immediately to receive emergency treatment. The actual fact is that you can find a lot of people who are not able to get a good deal of money from the internet. The surface of the skin of patients with urticaria will appear higher than the surface of the wind, redness, itching, rash shape and size, can occur in any part of the body, especially the trunk is common. Zhou Xian Coix, director of the specific symptoms of hives vary from person to person, some people have mild symptoms, not itchy and only red rash, some people occasionally slightly itchy, some people itch unbearable. Unconscious scratching after itchy skin is a phenomenon that many people cannot control themselves. Scratching can only have the effect of temporarily stopping the itch, and after a short while the itch comes back again. Scratching will undoubtedly strengthen the irritation of the skin, making the existing skin problems aggravated. This is especially true for hives, where the reaction to the wind and skin scratches deepens or scratches the skin, making it more difficult to treat. Another way to deal with itching is also extremely common, going into a pharmacy and buying ointments to apply to the affected area in order to get relief from the itching. The itch is severe to apply the cream vigorously on the itch relief and prominence in another place, repeatedly, a vicious cycle. “Severe local itching can be topical hormonal creams in moderation, but keep in mind that they can only be used for a short time and in small doses. Long-term use of hormonal creams, the use of the site can appear to varying degrees of skin atrophy, thinning, capillary dilation, skin flushing or bruising, bruising, dry skin, blackening or ichthyosis-like changes and other side effects.” Blind autonomy is not advisable, and the popular online prescriptions are not to be believed. For example, there is no definite scientific evidence that aloe vera has a therapeutic effect on hives, which has been widely circulated as a topical treatment for hives. It is recommended that patients use furnace glycerine lotion to apply to the affected area, which has a relatively good anti-itch effect and will not have any side effects for long-term use. Third, hives recede and then flare up means that you should seek medical attention. The actual hives, like many other diseases, are also acute and chronic. Acute urticaria starts quickly and disappears quickly, usually within 3-5 days can be cured; recurrent episodes of more than 6 weeks are chronic urticaria. Patients with chronic urticaria often have a red, swollen and itchy rash on their body, face or limbs from time to time, and often the more they scratch, the more itchy and swollen they become. The number of episodes varies from several times a day to once every few days. Some patients continue to be instinctively resistant to taking medications for hives. It is not advisable to resist medication, and the vast majority of patients are treated clinically with medication to achieve effective relief. The fact that urticaria returns soon after it subsides and becomes more severe means that the patient needs to be treated in a regular hospital as soon as possible. Antihistamines are the basic treatment for urticaria, especially chronic urticaria. The main antihistamines are H1 receptor antagonists and H2 receptor antagonists. Among the antihistamines, H1 receptor antagonists have strong antihistamine and anti-inflammatory mediator effects, so they will have a better therapeutic effect on various types of urticaria. Intractable urticaria can be treated with a combination of H1 and H2 receptor antagonists, thus improving the efficacy. Most patients with urticaria can obtain satisfactory results after treatment with antihistamines. For patients most concerned about the cost of treatment, urticaria medication is not expensive, the pills are usually taken only one a day, the price of each tablet 3-4 yuan, a month down to about 100 yuan. The second generation antihistamines have minimal reactions such as sedation and are acceptable to patients. However, due to the large individual differences of patients, the specific treatment time also varies greatly.
