2. Initial prevention of UTI as a way of minimizing antibiotic exposure

Antimicrobial prophylaxisAntimicrobial prophylaxis
• It has been demonstrated to be highly effective in reducing the risk of recurrent UTI in women
• Advocated for women who experience two or more symptomatic UTIs within six months or more over 12 months :- Continuous prophylaxis
- Postcoital prophylaxis
- Self-treatment
