My husband purchased these tablets when he was getting sick some time back. I had never take any type of product like this before so I never bothered to try them until I got sick and didn't have anything else to take! I will say first of all that I am not fond of the whole tablet style thing- I prefer a pill- but they work pretty well. And since they are the store brand I really didn't expect them to be that great but I am glad that I tried them. They do not work immediately but within 30 minutes which is a lot faster than a lot of other medicines I have tried that's for sure. When I went to buy more I was disappointed that they were not offered in flavors that are appealing to my taste buds. All that there was to choose from was cherry and citrus. I would prefer something more along the lines of strawberry or vanilla but to be honest I have never seen those types of flavors in medicine. I guess cherry flavors mask the medicine taste a lot better. These work pretty well but for me it didn't last very long. My husband thinks they are great on the other hand and takes them at the first sign of a cold.
