These are great to keep on hand for colds! It kicks a cold in the butt in only 1 or 2 days! Mix it up withhalf glass of water, stir it around and down the hatch and you will feel much better in a day! They have flavored ones, but i like the original. PLOP, PLOP, FIZZ, FIZZ! Highly recommend! It works! Not cheap, but worth getting rid of that cold fast...cheaper than a drs visit!

Works great for my husband

My husband will only take these, he says it works quickly. If you have asthma or COPD do not take these, I found that out the hard way, the acetaminophen will cause bad breathing problems for you, at least it did for me.
