How can I treat a UTI at home?

There are no home remedies for the treatment of a UTI. Some preventive measures include urinating immediately after sex, staying consistently well-hydrated, and possibly supplementing with probiotics, cranberry, d-mannose, or uva ursi. Research is mixed regarding most of these interventions, but it’s important to note that even if they are helpful, their use is for prevention alone; none of them will reliably treat an existing infection.
