I purchased Chloraseptic Sore Throat Lozenges because my throat was for some reason was really dry. This usually means a cold or a flu is coming for me, but I didn't have any other symptoms. I never got sick, but I continued to use the lozenges while my throat healed. I would let a lozenge sit in my mouth until it dissipated. I received some relief and I was able to eat and drink without having too much discomfort swallowing. I took around 20 lozenges over a 3 day period until my throat got better. I eventually did get a cold later down the road and I tried taking these lozenges, but they had very little affect on my sore throat. I would take a lozenge and as soon as it dissolved I would be in pain again. I decided to pick up the extra strength of this product and it yielded the same results. The only use I found for these lozenges is to use during and after long singing, speaking, and screaming engagements. I found that on all of these occasions I have been able to avoid losing my voice by taking Chloraseptic Sore Throat Lozenges.
