For Streptococcal Infection "Was prescribed Penicillin K V for strep twice a day, 500 mg. Am now 5 days into it, and the strep pain has been totally cured, however, the stomach cramps from the medicine are almost enough to make me quit the medicine itself."

Penicillin v potassium for Tonsillitis/Pharyngitis "I don’t know if anyone else has had this issue, but this medication, Penicillin VK, gave me side effect symptoms of bad headaches, body aches, stomach cramps, cold feet, and numb feet. It was good for clearing up the tonsillitis, I still don’t feel that great, but it has stopped me from feeling so rubbish. I wouldn’t take this medication again, though, due to the side effects."

For Streptococcal Infection "Today's my second day of taking this antibiotic, and so far, I can breathe better and actually swallow, but my stomach has been non-stop grumbling and I feel lightheaded. I throw up once in a while, but other than that, it helps."
