Treatment of Recurrent Cystitis in Women: Managing Three or More Episodes per Year

This protocol addresses recurrent cystitis specifically in women who experience three or more episodes per year, or two or more episodes within any six-month period. The pattern of recurrence in this population warrants a structured preventive strategy beyond episode-by-episode treatment.

Female sex is a key defining factor in this protocol. Recurrent cystitis is defined by at least three episodes per year or two episodes in the last six months. Menopausal status influences which preventive options are appropriate, as the underlying susceptibility factors differ between pre-menopausal and post-menopausal women.

The protocol centres on non-antibiotic prevention. Available options span behavioural, hormonal, and supplemental interventions — with the choice guided by menopausal status and individual factors. The full structured regimen specifies which options apply and under what conditions.
