It says UK/GB with your name, but I wonder if you're in a developing country where pharmacists often act as health care providers for simple diagnosis and treatment. However, that always means guesswork, especially in choosing an antibiotic for UTI. You now need to get direct medical care from a clinic or doctor to confirm diagnosis and probably change to a different antibiotic.
