I would definitely utilize the homeopathic oscillicocinum. It will shorten the duration of any flu and possibly avert becoming very sick if started early. You only need to use 2 or three pellets under the tongue...not the whole container like the directions say. You can take it 15 minutes apart and then extend the time between doses as the symptoms decrease. Put the pellets in the lid and have a clean mouth when you use it. Homeopathics are given in response to a symptom picture, so you would only give to alleviate specific symptoms. This is also good for sore throats. These are so easy to take if you are sick or feverish. There are other remedies for the flu that are combination remedies, which are also effective. Oscillicocinum is just the remedy that the European Commission has endorsed and they are very reputable. Good luck...it sucks to be sick and have sick kids.
