Guaifenesin 100mg Capsule x 1

I was having chest pain and throat trouble swallowing because I would cough but nothing would happen. After my first single dose of 500 mg I started to feel relaxed I wouldn't cough much but when I did the phone cleared with it every time. After 1 hour the pain in my throat and my breathing and the rest of my respiratory system self back to normal I don't know what the result will be when I stop taking it I hope it's clear and it's going to be a once a day tablet.
