DosagePaediatric population
The safety and efficacy of ALLERGIFLASH 0,05 %, eye drops in solution in single-dose container, in children aged less than 6 years have not yet been established. These data are limited (see Pharmacodynamics).
Adults and children aged at least 6 years:
The usual recommended dose is 1 drop in each eye, 2 times a day.
This dose may be increased, if necessary, to 1 drop 3 to 4 times a day.
The eye drops should be used at regular intervals.
Treatment should not be continued beyond 5 days without medical advice.
Method of administration:
- Wash hands thoroughly before instillation.
- Avoid touching the eye or eyelids with the tip of the single-dose container.
- Instil one drop of eye drops into the conjunctival sac of the eye, looking upwards and gently pulling the lower eyelid downwards.
- With the eye closed, carefully wipe away the excess, particularly from the cheek.
- In order to avoid systemic effects, it is recommended to press the inner corner of the eye for 1 minute after each instillation.
- Discard the single-dose container immediately after instillation.
If concomitant treatment with another eye drop is used, space the instillations by 15 minutes.
The quantity of eye drops in a single-dose container is sufficient for treating both eyes.

Hypersensitivity to the active substance or to any of the excipients listed in section Composition.Warnings and precautions

Fertility, pregnancy and breastfeeding
Pregnancy:No data concerning the human species is available. Given the negligible systemic passage and the fact that no embryotoxic or teratogenic effect has been reported in animal experiments, the use of ALLERGIFLASH 0,05 %, eye drops in solution in single-dose container may be considered with caution during pregnancy.
Breastfeeding:
Due to the lack of data, the use of levocabastine is not recommended during breastfeeding.
Driving and using machines
A transient visual disturbance due to slight irritation upon instillation of the eye drops may be experienced by the patient. In this case, it is recommended to wait until vision returns to normal before driving a vehicle or using a machine.Adverse effects

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continuous monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals should report any suspected adverse reaction via the national reporting system: National Agency for the Safety of Medicines and Health Products (ANSM) and the network of Regional Pharmacovigilance Centres.

Overdose
Sedation following accidental overdose cannot be ruled out.
In case of overdose, rinse thoroughly with sterile physiological saline.
Pharmacodynamics
Pharmacotherapeutic class: selective H1 antihistamine, ATC code: S01GX02.
Levocabastine is a potent, selective H1 antihistamine whose action is rapid and prolonged.
After ocular instillation, it rapidly relieves for several hours the symptoms of allergic conjunctivitis (pruritus, erythema, lacrimation, eyelid oedema, chemosis).
Paediatric population
Paediatric studies conducted in the population of children aged 6 to 18 years have confirmed the efficacy of levocabastine in ocular instillations. Usage data in children aged 4 to 6 years have been published. Due to their limited nature, the benefit-risk ratio must be taken into account when using ocular levocabastine in children aged at least 4 years and under 6 years.
Pharmacokinetics
After ocular instillation, levocabastine is gradually and partially absorbed by the mucosa.
Plasma concentrations are too low to produce systemic effects.
Preclinical safety
Non-clinical data for levocabastine from conventional repeated-dose toxicity studies, conducted by oral, intravenous, dermal and ocular routes in different animal species (rat, dog, rabbit), did not reveal any particular risk for humans.
Reproduction studies performed in mice and rats by oral route showed that levocabastine has no adverse effect on reproduction up to 20 mg/kg/day in rats and up to 40 mg/kg/day in mice.
Levocabastine has not shown mutagenic or carcinogenic potential.
No ophthalmological abnormalities were observed in rabbits after instillation of one drop of ALLERGIFLASH 0,05 %, eye drops in solution in single-dose container 4 times per day for 4 weeks.
Storage conditions
