Antihistamines

Preparations that are united by such a general term as "antihistamines" are found in the home medicine cabinet of almost every family. This only says that these drugs are quite popular, 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 start to describe the effect of the drug and its side effects, it should be recalled that you must start taking it only according to the indications and prescription of the doctor who will thoroughly study the problem and prescribe the appropriate dosage.

As a rule, antihistamines are prescribed for the treatment of allergies. The appearance of an allergic disease occurs due to the penetration into 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, this 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, bronchial spasm and lowering of blood pressure.

When these symptoms appear, doctors prescribe antihistamines that affect histamine. In the process of treatment, its quantity decreases, its release practically ceases, and the one that has already begun its action 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 person inhales something, 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 all such medicines is not pronounced, that is, if there is an allergy, for example, to citrus, it does not mean that it can be eaten in a snack 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.

At present, such modern antihistamines as diprasine, diazolin, tavegil, suprastin and fenkarol are prescribed to eliminate allergic symptoms. 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: pills, syrups, candles and even injections.

The main goal of these drugs is to eliminate allergy 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. To take them to people whose work or way of life requires quick reaction is very necessary. 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.
