I've been on antibiotics (flucloxacillin) for 4 days (out of 7) for a small infected burn.
For the last 3 days I have noticed that my urine absolutely stinks! I can only assume that what I am smelling is the antibiotics, and not something more serious.
I've had several UTIs before, and sometimes they make my urine smell, but this antibiotic says in the leaflet that it can be prescribed to treat UTIs, so I don't think I could have a UTI at the same time as taking these.
