Drugs that are united by such a commonconcept, as "antihistamines", are found in the home medicine cabinet of almost every family. This only indicates that these drugs are popular enough, but it is likely that most people who take them, often have no idea about what it is like this or that antihistamine drug works and what is the result in the end may cause.
Before you begin to describe the actiondrug and its side effects, it should be recalled that it must be started only according to the indications and prescription of a doctor who will thoroughly study the problem and prescribe the appropriate dosage.
As a rule, antihistamines are prescribedfor the treatment of allergies. The appearance of an allergic disease occurs due to the penetration of the human body of certain allergens. When they enter, the production of biologically active substances begins, which cause the disease. The most common such substance is histamine. If a person is healthy, the substance in his body is inactive. If there is an allergic reaction to a substance, histamine is immediately released, which leads to the appearance of allergic symptoms. It can be a runny nose, various redness, a rash, a spasm of bronchial tubes and lowering of arterial pressure.
When these symptoms appear, doctors prescribeantihistamines that affect histamine. In the process of treatment, its quantity decreases, its release practically ceases, and the one that has already begun its effect is also neutralized. So, the most important goal in using such drugs is to eliminate, as well as prevent symptoms of increased histamine release.
Allergies can be respiratory - when a personsomething inhales, maybe food - something eats, contact - when applied to the skin of a drug or cream, also pharmacological - taking drugs in response to which the active release of histamine begins.
It is important to know that the preventive effect of allsuch drugs are not pronounced, that is, if there is an allergy, for example, to citrus, it does not mean that it can be eaten in a bite with an antihistamine drug, but it is better not to eat at all. But there are such desperate situations as an allergy to poplar fluff, it can not be avoided, and here antihistamines are prescribed.
Currently, to eliminate allergicsymptoms are prescribed such modern antihistamines as diprazine, diazolin, tavegil, suprastin and fenkarol. These medicines have been used for a very long time, because their positive and negative effects are known thoroughly. Their medicinal form can be completely different: tablets, syrups, candles and even injections.
The main purpose of these drugs is to eliminateallergy symptoms. By the way, antihistamines with itching help just fine, if it is caused by an allergic reaction, of course. All such medications have a sedative effect to a greater or lesser degree - they soothe, slow down a little and have a hypnotic effect. It is very necessary to take them to people whose work or lifestyle requires a quick reaction. Therefore, it is said that the appointment of drugs to eliminate allergic symptoms should be carried out only by specialists. The person who works behind the wheel of a car will be assigned, for example, fenkarol, since it has less pronounced sedative effects than the same suprastin.
Summing up, it can be said that all antihistamines have common advantages, they really perfectly eliminate allergic symptoms, thereby making life easier, and still affordable.
