I have Penicillin VK 500MG tablets from when I had a couple of teeth removed. They expired 8/29/13. Lately, my throat has been sore for over a week and it is swollen. Could this help? I m 27, 5 7 and weight approximately 185lbs. No, I m not overweight, I lift weights in the gym. I haven t had a cold or flu in over 2 years, and aside from this, I m a very healthy person.
