Used for two children - 8 and 1.6. I can not say whether so they are effective at the end of the winter season, they still picked up some trash, but came out of it in just a couple of days. At least, not repugnant to the taste, have no side effects as antibiotics and are not as useless as the type of drugs groprinozin, well, the price is quite loyal compared to that offered by our pharmacy. Packaging, we drank together, took another, just in case, let them lie in the medicine cabinet. UPD. A year has passed since my review, I would like to add - a good thing. I give the child two years as an emergency help if you suddenly have visited in the company of people who are sick, and how to prevent epidemics. For a year he did not get sick, although my husband from work brought infection and older children from school.
