I have been using these lozenges for about 5 months now. Around 5 months ago I had severe complications to immunotherapy which made me go into anaphylaxis. I ended up in the hospital and due to the immunotherapy I also developed oral thrush (I have had strep, sinus infections, and the flu but there is no throat pain comparable to oral thrush). I have since been healed from oral thrush but due to the long infection I developed a tonsil cyst and my throat is mysteriously still sore. I have been to many doctors but no one knows what to do for me. The only relief I get is with these lozenges and I am incredibly thankful for them! If you have the flu, mono, strep, or a sinus infection, these should do the trick for the first couple of days (when the throat feeels like fire). If you are someone like me that is suffering from a mysterious chronic sore throat or you have a tonsil cyst, these can provide relief for a short time but enough to give you hope and be a reminder of the painless times.
