I started buying this brand of medicine a few years back when there were a lot of recalls on children's medications. It quickly became my go to medicine for anything any of my kids ever had. It is used for ages 2 through 11 which is prefect for my kids. It comes in a variety of flavors so they have fun actually picking the flavor out. No one wants to take a nasty tasting medicine. The Flu version of this is great. It does everything it says it does. When my daughter had the flu I gave her this regularly. It usually kicks in within about half an hour which is why I overlap it by about 30 minutes just to ensure the medicine is doing its job round the clock. A HUGE favorite of mine is that this medicine almost immediately dries my daughter's nose. A few uncomfortable hard boogers is better than having a nose that is running like a faucet. This also works wonders at night. It is not a night time version but it still works almost as good as anything else. Coughing is really kept at bay with this.
