Conducting ASIT is indicated in those cases when it is impossible to exclude the contact of a sensitized patient with an allergen, and is under the control of an allergist doctor.
Before taking the allergen should read the instructions for use of the drug, check the name of the allergen, the amount of PNU / ml, shelf life.
It is necessary to check the integrity of the vials, as well as the absence of turbidity and foreign particles.
Allergen is prescribed for oral administration once a day (morning or evening), 30 minutes before meals.The required amount of drops of the allergen is buried in a teaspoon. To the allergen you can add water with flavor additives at your choice. Allergen should be kept under the tongue for 1-2 minutes, then swallowed. Do not drink, do not seize.
ASIT can be carried out according to two schemes. Each scheme includes a course of basic and supporting immunotherapy. After the main course of ASIT, a course of maintenance immunotherapy should be conducted for 3-5 years.
The first scheme (classical) ASIT
The main course of treatment with an allergen is carried out for 5 months.

Allergens of lower concentrations (0.1, 1.0, 10 PNU / ml) are prescribed, usually three times a week (for example, Monday - Wednesday - Friday or Tuesday - Thursday - Saturday). With the appointment of elevated concentrations (100, 1000 PNU / ml), the intervals between doses are prolonged and administered twice or once a week.
Supportive immunotherapy
Within 3-5 years after the treatment, it is necessary to take 10 drops of the allergen withconcentration of 1000 PNU / ml once a week.
The second scheme (accelerated) main course treatment is carried out within 50 days.

ASIT begins with the lowest concentration of allergen (0.1 PNU / ml), then in increasing order, they pass to the following concentrations (1, 10, 100, 1000 PNU / ml).
Each concentration of the drug is always used from one drop per day, and every next day the amount of drops is increased by one drop. After reaching the number of ten drops (the 10th day), the next day, immediately prescribed one drop of the drug at the next higher concentration (the intervals between allergen receptions with different concentrations are unacceptable).
Supportive immunotherapy
Within 3-5 years after the treatment, it is necessary to take 10 drops of the allergen with a concentration of 1000 PNU / ml 3 times a week.
Recommendations for the doctor
The treatment regimen can be changed depending on the patient's condition.
If the patient is well tolerated (no symptoms of an allergic disease), then with maintenance therapy, you can take the maximum dose of the allergen.
In case of symptoms of an allergic disease and worsening of the patient's condition, it is recommended to reduce the dose of the allergen by half the maximum dose.
