1. What is Perosall C and what is it used for

Perosall C is intended for desensitization of individuals with an allergy to weed pollen. The medicine is in the form of a solution for sublingual use in four increasing concentrations. Each solution contains a mixture of allergens derived from weed pollen. The treatment involves the systematic administration of increasing doses of allergens to produce a state of tolerance (lack of reaction of the body to the allergen). This leads to the alleviation or disappearance of allergy symptoms during the weed pollen season.
The decision to undergo sublingual desensitization is made exclusively by a specialist allergist, based on the patient's history, allergic symptoms, skin diagnostic tests, and/or the level of specific IgE antibodies.

2. Important information before using Perosall C

When not to use Perosall C:

  • if the patient is allergic to any of the excipients listed in section 6
  • if the patient has been diagnosed with an autoimmune disease
  • if the patient has been diagnosed with a malignant disease
  • if the patient has been diagnosed with tuberculosis
  • if the patient is constantly being treated with beta-adrenolytics (e.g. during coronary disease, with high blood pressure)
  • in patients with clinically apparent severe immunodeficiency
  • in case of lack of cooperation from the patient
  • in patients with acute infectious diseases with fever (desensitization can be resumed after 5-7 days after the infection has subsided, after consultation with an allergist)
  • during exacerbation of chronic infections (desensitization can be resumed after 5-7 days after the exacerbation has subsided, after consultation with an allergist)

after the exacerbation has subsided, after consultation with an allergist)

  • in patients with unstable circulatory system diseases, e.g. unstable coronary disease (requiring periodic use of beta-adrenolytics or ACE inhibitors)
  • in patients with severe, unstable asthma - with spirometry measurements - FEV1 below 70% of the normal value
  • in patients with severe atopic dermatitis in exacerbation.

Warnings and precautions

  • if undesirable effects occur, the doctor should be informed immediately
  • on the day of taking the medicine, one should avoid excessive effort, drinking alcohol, and overheating (e.g. sauna, hot shower, sunbathing).

Children

  • Perosall C should not be used in children under 5 years of age.

Perosall C and other medicines

  • concomitant use of anti-allergic medicines, e.g. antihistamines, cromones, corticosteroids, may modify (shift in time) the actual reaction to the medicine
  • if desensitization (basic treatment) and vaccination are planned at the same time, in accordance with the Vaccination Program, desensitization should be started after vaccination
  • if maintenance doses and vaccination are planned at the same time, in accordance with the Vaccination Program, vaccination should be performed between maintenance doses and desensitization should be continued according to the scheme (do not use desensitization and vaccination on the same day).

You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.

Perosall C with food and drink

The medicine should be taken on an empty stomach, at least 15 minutes before a meal.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, suspects she may be pregnant, or plans to have a child, she should consult her doctor before using this medicine.
During pregnancy and breastfeeding, therapy with Perosall C should not be initiated. If such treatment has been started before pregnancy, it may be continued in agreement with the attending physician. Currently, there is a lack of sufficiently documented data on the use of allergen desensitization in pregnant women. The potential risk to the mother and fetus is therefore unknown.

Driving and operating machinery

The medicine does not affect the ability to drive vehicles or operate machinery.

3. How to use Perosall C

Perosall C should be used before the pollen season, before the onset of allergy symptoms.
Take on an empty stomach, at least 15 minutes before a meal. Tilt your head back slightly and put the recommended number of drops under your tongue. The bottle, after being tilted, automatically doses the drops thanks to the appropriate design of the dropper. The medicine can be given to a child by a caregiver.
Treatment is divided into two stages:

  • basic treatment - gradual dose increase
  • maintenance treatment - constant dose.

Basic treatment

Unless the doctor recommends otherwise, the medicine is used daily, with the dose increased by one drop every day until the highest maintenance dose, i.e. 10 drops of concentration 4, is reached, according to the following scheme:

Basic treatment scheme

The above dosing scheme should be considered as a guideline and example of treatment. The doctor may modify the scheme depending on the patient's condition and their reaction to the treatment.
In case of allergic symptoms such as:

  • swelling of the eye and face area, runny nose, conjunctivitis,
  • difficulty breathing, swallowing, the dose should be reduced, using fewer drops or a lower concentration, for at least 3 days. Then, the dose should be increased by one drop daily, according to the basic treatment scheme.

Maintenance treatment

The maximum, individual, well-tolerated dose of concentration 4should be used 2 times a week. Treatment should be ended 2-3 weeks before the pollen season.
Note:
In the case of patients who are particularly sensitive to pollen allergens, treatment can be started with concentration 0-1 JS/ml, which is prepared on individual order.

Before using Perosall C, you should check the expiration date on the packaging.

Taking a higher dose of Perosall C than recommended

Local and general undesirable effects may occur, including anaphylactic shock, the symptoms of which are: sudden drop in blood pressure and loss of consciousness.
In case of taking a higher dose than recommended, you should immediately consult a doctor or pharmacist.

Missing a dose of Perosall C

You should take the last used dose, and then continue treatment according to the scheme.

Discontinuing Perosall C

If basic treatment is discontinued for more than 2 weeks, it should be resumed using half of the last dose used and well-tolerated (dose not causing allergic symptoms). In case of a longer break than 4 weeks, treatment should be started from concentration 1.
Discontinuation of desensitization may occur in case of infection or exacerbation of chronic infections (in accordance with section 2 of the leaflet). Desensitization can be resumed after 5-7 days after the infection/exacerbation has subsided, after consultation with an allergist.
In case of any further doubts related to the use of this medicine and discontinuation of treatment, you should consult an allergist.

  • worsening of rhinitis, asthma exacerbation
  • gastrointestinal disorders, abdominal pain, diarrhea
  • generalized urticaria, generalized skin itching

These symptoms are usually short-term and resolve on their own.
