Method of administration:
- Shake the ampoule before opening it.

- Fill the bottle with the contents of one ampoule.
- Stand in front of a sink, tilt the head slightly backward and choose one of the following administration methods:
- Let ACTISOUFRE run into one nostril by pressing the dropper bottle. Breathe through the mouth while repeatedly pronouncing the syllable "ké". Keep the head slightly tilted back for a few moments (about 30 seconds) to allow the product to contact the secretions. Then straighten the head and swallow the secretions.
- If you wish to swallow the minimum amount of secretions, you may proceed as follows:
- block one nostril, let ACTISOUFRE run into the other nostril by pressing the dropper bottle and perform 3 to 4 back-and-forth breathing movements through the nostril containing the liquid, then straighten the head and expel the solution by exhaling through that same nostril.
- Repeat the same procedure for the other nostril.
- Repeat until the contents of the dropper bottle have been fully used.
- After each use, rinse the dropper bottle and tip thoroughly under running water and dry them carefully.

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 national reporting system: National Agency for the Safety of Medicines and Health Products (ANSM) and the network of Regional Pharmacovigilance Centres - Website:www.signalement-sante.gouv.fr.
Pharmacodynamics
Pharmacotherapeutic class: Other cold remedies, ATC code: R05X
Mechanism of action
Sulfur supply from sodium sulfide and trace elements and vitamins from yeast Saccharomyces cerevisiae.
SPECIAL PRECAUTIONS FOR DISPOSAL AND OTHER HANDLING
- Shake the ampoule before opening it.
- Any residual aggregate that may remain is not active. It is formed of yeast cell walls which have previously released their soluble components (yeast extract rich in vitamins, trace elements, ...) into the ampoule. This residual aggregate therefore does not alter the activity of the product.
To empty a self-breaking ampoule into a container (the dropper bottle or a glass), proceed as follows: take one tip between the thumb and index finger and, with a firm movement, snap it open. Hold the ampoule open above the container and break the other tip in the same way.
- When the ampoule is opened, the smell reveals the mixture of sulfur and orange blossom essence.
Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
