These are the best ways to fight a cold and, from personal experience, the flu, before it starts.
Even though Cold eeze and zinc lozenges in general do not claim to help with the flu and just claim to help to shorten the time of the cold, I am convinced it helps prevent a cold and even flu (though only have 2 case reports of me and my husband) and look forward to seeing randomized, controlled, double blinded studies, as this has happened a couple of times these last 2 years.
Also since many pneumonias start off as a early bronchitis from either a virus or bacteria, it will be interesting to see if zinc lozenges might help prevent pneumonia in some patients.
For the young kids (younger than 7), I hold the Cold Eeze in my hand and let them lick the lozenge as much as possible so they can get the zinc and not choke on the cough drop. I cannot wait till they make little lollipops for them. I make sure the child who is getting sick (is starting with sneezing in a house where the virus is making its rounds; or runny nose or says their throat is starting to hurt: you have to teach kids early to tell you as soon as they feel a little discomfort or pain in their throat for this to work) eats a piece of bread before I give the Cold Eeze as it can really upset the stomach if eaten on an empty stomach.
The only short term side effects I could find with zinc on line:
-upset stomach if taken on empty stomach
-loss of smell if a great deal is taken.
