Penicillin v potassium for Bacterial Infection "I'm taking this for a tooth infection that started to spread. My lymph nodes were very painful and swollen. This med makes me feel dizzy, anxious, and a pressure in my head. It reminds me of taking cold medications. I hate that part of it. But it also seems to be fighting this tooth infection. My tooth and lymph nodes are not hurting as badly, and swelling has gone down. Still have a few days left, though."

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."

Penicillin v potassium for Bacterial Infection "Been taking now for 5 days! Told to take for 10 days! Abscess on my wisdom tooth, which is impacted, and swollen gums and glands! Swelling went down some, but pain is still very active! No side effects, minus a headache here and there, but that may be from the pain pressure of the wisdom tooth! Feel like I should have some type of relief by now, but I have 5 more days! Will see how this goes."

For Tonsillitis/Pharyngitis "I had barely any side effects on this, and my strep throat went away within two days of taking it. Sore throat, swollen tonsils, and swollen lymph nodes were all gone. The only side effects I had were some loose motions, mild stomach cramping like gas pains, and headache. But my appetite was normal, no nausea or vomiting, and I was able to continue on with my normal life throughout this medication. I was allergic to it as a kid (got hives all over my body), so I was nervous about taking it, but it seems that I grew out of the allergy."

Penicillin v potassium for Bacterial Infection "I don't like the Penicillin VK pill. I was taking this for swollen gums and a bad tooth, and it made me depressed, feverish, weak, and caused a slight headache. It did not seem to work much on my gums. As soon as I stopped taking it, I felt better."

For Streptococcal Infection "500 mg four times a day. Felt really bad, sick, headache, sweats, and shivers. Feel the dose was too high as I felt better when I halved the dose."
