Concentration (Standardised Units (SU))/0.5ml)
POLLINEX Trees Extension Course contains equal proportions of 3
selectively purified allergen extracts of pollen from the following trees:
The allergens have been converted into allergoids by treatment with
glutaraldehyde and are adsorbed onto L-tyrosine. The allergen extracts are
characterised and standardised through immunological and biochemical
methods to ensure batch-to-batch consistent allergen content and allergenic
potency. Major allergens are measured in selected extracts. Standardisation is
reflected by the assignment of Standardised Units (SU).
For the full list of excipients see section 6.1.

2000 SU – 0.5ml
The Extension Course consists of three injections of the maximum dose of 2000
SU/0.5ml. (If the maximum dose is not tolerated, treatment can take place at a lower
dose). The first injection should be given about 14 days after the last injection of
POLLINEX Trees. Subsequent injections should then be given at intervals of 2-4
weeks. If the season is imminent, the interval can be reduced to 1 week.
The maximum dose of 0.5ml must not be exceeded.
The course should be completed before the onset of the tree pollen season.
Do not use during the tree pollen season.
POLLINEX Trees Extension Course should be given after POLLINEX Trees (PL
17087/0007) for continued clinical improvement.
It is recommended that the allergy vaccine should be given in each of three successive
For children from the age of 6 years and adolescents, the same posology regime as
adults is recommended.
POLLINEX Trees Extension Course should not be used in children under 6 years of
Method of administration
For subcutaneous injection (see section 6.6 for instructions on handling).
It should be administered at a constant pressure by subcutaneous injection to the
middle third of the lateral posterior aspect of the upper arm. The injection sites should
be alternated between arms, e.g. 1st and 3rd injection in the right arm and 2nd injection
in the left arm. Repeated injections at one injection site should be avoided. Do not
inject into a blood vessel or intramuscularly. The patient should be instructed not to
rub the injection site.
Contraindicated in patients with asthma because they are more likely to
develop life threatening reactions.
Patients should not be given an allergy vaccine if they have febrile infections
or inflammation of the respiratory tract; irreversible secondary changes of the
reactive organs (emphysema, bronchiectasis etc); severe chronic and
inflammatory diseases, immunopathological conditions, active tuberculosis of
the lung and eyes, severe mental disorders or are receiving beta-blocker
Hyposensitisation injections should not be given to patients with systemic or
local infection or who have suffered from a febrile condition in the 24 hours
preceding the intended dose, or if they have immunodeficiency or an
If tyrosine metabolism is disturbed, especially in the case of tyrosinaemia and
alkaptonuria, or there is known hypersensitivity to any of the excipients
contained in POLLINEX Trees Extension Course (see section 6.1), the allergy
vaccine should not be used.
If the patient is pregnant/discover they become pregnant whilst receiving
treatment POLLINEX Trees Extension Course should not be started or
continued during pregnancy as pregnancy may change the patient's
sensitisation level to a degree that cannot be foreseen. Please refer to section
4.6 Fertility, pregnancy and lactation.
Special warnings and precautions for use
The individual tolerated dose should not be exceeded.
Treatment of patients should only be carried out where full facilities for cardiorespiratory resuscitation are immediately available.
Epinephrine/Adrenaline Injection should always be kept at hand when giving any
allergen specific immunotherapy.
Patients should be kept under observation for the first 60 minutes after each injection.
This period should be extended if even mild symptoms or signs of hypersensitivity
develop and patients should be maintained under observation until these have
completely resolved. A severe and prolonged adverse reaction may necessitate
As with any specific immunotherapy there is a risk of anaphylactic shock.
Tingling, itching and burning sensations on the tongue, in the mouth, throat or
particularly on the palms and soles. This may be immediately followed by shock with
cyanosis, hypotension, tachycardia, bronchospasm and unconsciousness.
Further clinical signs are: anxiety, restlessness, urticaria, dizziness, laryngeal oedema
with dyspnoea, nausea and vomiting, respiratory and cardiac arrest.
Severe and potentially life-threatening reactions require fast and effective emergency
The treatment of allergic reactions is based on current medical guidelines.
In the event of simultaneous vaccination against viral or bacterial pathogens, there
should be an interval of at least one week between the last injection of the allergy
vaccine and the day of vaccination. Hyposensitisation therapy may be continued two
weeks after the vaccination, using half of the last dose administered. Afterwards, this
amount can be increased according to the dosage chart at intervals of 7-14 days.
Use with caution in patients with cardiovascular deficiency.
Patients should be warned not to eat a heavy meal immediately before an injection is
due to be given.
Injections should be given at a constant pressure by the subcutaneous route. Do not
inject into a blood vessel or intramuscularly. Do not rub the site of injection.
The patient should not take any strenuous physical exercise for 12 hours following
All patients should be advised to contact the doctor immediately in the event of an
Interaction with other medicinal products and other forms of interaction
Concomitant therapy with symptomatic anti-allergic agents (e.g.
antihistamines, corticosteroids, mast cell stabilisers) may affect the tolerance
level of the patient. A reduction of the dose after discontinuing treatment with
these symptomatic preparations may be required.
During hyposensitisation, exposure to the causal allergens and allergens crossreacting with them is to be avoided as far as possible.
POLLINEX Trees Extension Course is contraindicated in those receiving
Beta-blockers, please refer to section 4.3.
Fertility, pregnancy and lactation
The use of POLLINEX Trees Extension Course is contraindicated in
Effects on ability to drive and use machines
Occasionally the injection may cause mild drowsiness; the patient should be
instructed not to drive or operate machinery if this is the case.
If the injection intervals and dosage regimens are followed exactly and the dose is
individually increased in an appropriate manner, allergic side reactions to treatment
with the allergy vaccine are rare. They are usually mild but local and/or systemic
reactions must be anticipated, in which case the treatment must be immediately
discontinued. For these reasons an emergency kit should be immediately available.
As a precautionary measure, each patient must be kept under observation for at least
60 minutes after injections, after which time a medical assessment is made.
Such as swelling or irritation.
These may require symptomatic treatment if they are severe or
persist. In extremely rare cases, granuloma may be observed,
especially if the injection was too superficial.
Such as rhinitis or urticaria.
Fatigue occasionally occurs after injection of the vaccine.
Atopic eczema may be exacerbated by hyposensitisation.
Such as severe wheezing or bronchospasm.
Description of selected adverse reactions
Anaphylactic reactions/anaphylactic shock
Severe anaphylactic reactions or anaphylactic shock have been reported in individual
cases. Anaphylactic shock can develop minutes after administration of any allergy
immunotherapy, often before a local reaction has appeared (see section 4.4).
Typical warning symptoms of anaphylactic shock are described in section 4.4.
In rare cases, adverse reactions may occur even a few hours after the
hyposensitisation injection, in which case the patient should inform their attending
doctor before the next injection. When in doubt especially after the appearance of
systemic reactions the patients should seek medical advice/treatment immediately.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is
important. It allows continued monitoring of the benefit/risk balance of the medicinal
product. Healthcare professionals are asked to report any suspected adverse reactions
via the Yellow Card Scheme website: www.mhra.gov.uk/yellowcard.
If a patient receives an overdose of an allergy vaccine, the likelihood of an adverse
reaction is increased.
Reactions are characterised by symptoms ranging from slight swelling or irritation at
the site of injection to anaphylaxis.
See 4.8 Undesirable effects.
The usual precautions should be followed i.e.
Patients should be kept under medical observation for at least 60 minutes after each

Pharmacotherapeutic group: allergens
ATC Classification: V01A A05
Immunotherapy with POLLINEX Trees Extension Course is recommended for
patients who are sensitive to specific pollens. The effectiveness of
immunotherapy in reducing symptoms has been established by controlled,
The specific pollen allergens incorporated in POLLINEX Trees Extension
Course have been modified by glutaraldehyde treatment and adsorbed onto Ltyrosine with the result that allergenicity is reduced (thus increasing tolerance)
while maintaining immunogenicity (related to efficacy).
Although the immunological events are not clearly understood, the production
of antigen specific IgG antibody, suppression of specific IgE and decreased
mediator (histamine) release from basophils are important factors.
Therapeutic effects of specific pollens immunotherapy are allergen-specific
and dose dependent.
POLLINEX Trees Extension Course contains glutaraldehyde-modified
extracts of specific pollens adsorbed onto L-tyrosine. The adsorbate L-tyrosine
is a natural amino acid which is metabolised in the body and ensures a slow
release of the active material (the allergoid) is released more slowly. This
results in a prolonged and efficient desensitising effect and improving
