Love this!
Absolutely love this medicine. Perfect for those who are having throat pain but don’t have access to doctor immediately. Helps with immediate relief. Does not make you drowsy or tired. Not a bad taste either.

Works really well
Unfortunately had to use this during a pretty rough cold, but it really helped with my cough and congestion. It kicked in faster than I expected and made it easier to sleep through the night. The taste isn’t amazing obviously, but honestly not nearly as bad as some other cold medicines I’ve tried.

Happy Loyal Amazon Customer
This medicine was highly recommended to me after a long sleepless night with fever chills and a painful cough. I was preparing myself to go to the VA emergency room because of how awful I was feeling, but then, I look outside my door and there was my medicine, dropped off earlier than expected. It’s almost like someone knew I needed it badly. So this review is for Amazon. For offering such reliable service when you need it most. The medicine has worked well. I feel much better.
