I have been using these drops for 25 years. I always have them in stock. They are in my first-aid kit every time I travel. At the first scratch, I take the drops immediately and rinse my mouth and gargle with them for about 30 seconds. For day trips, I fill a nasal spray bottle washed out with boiling water with the drops. This allows me to spray about 10 puffs comfortably into my mouth and throat, which stops the coughing and can almost always prevent bronchitis. The drops used to be called Tonsilgon.

Imupret N drops are very practical during the cold season. At the slightest sign of a cold, I take the drops as described in the package leaflet and I usually feel better the next day. I am very enthusiastic and have been able to ward off infections easily during the cold season.
