Hello, I am taking penicillin VK 500MG Tabl and I am noticing that my right arm is very weak and it it painful to move the arm. Should I stop taking this prescription? I was prescribed this because I had a small abcess under one of my teeth. Thank you in advance.
Hi, Yes, although it is rare but penicillin can cause pain and muscle weakness. Based on the history you seem to have hyperkalemia (increased potassium level) apparently caused by using penicillin VK-500 tablets. I advise you to stop taking this Chat Doctor.
