A urinary tract infection (UTI) can be very uncomfortable, and should be treated as soon as possible so it doesn’t develop into a more serious infection. A UTI occurs when bacteria (usually from the bowel) enters the urinary tract via the urethra (the tube that goes from the bladder to the outside). The bacteria can cause infection in the urethra, the bladder or the kidneys.The most common symptoms of a UTI is a painful, burning sensation when passing urine, needing to urinate often, passing only a small amount of urine at a time, having the sensation of incomplete emptying after urinating, needing to urinate urgently (without much warning) and a feeling of discomfort just above the pubic area. If you meet certain criteria, one of our specially trained pharmacists can give you an antibiotic called Trimethoprim, without a prescription. They’ll ask you a few questions to see if Trimethoprim is appropriate for you or recommend that you visit your doctor.
