You are right. It is true that frequent antibiotic use can predispose to fungal infections, but this happens more often with a depressed immune system. Also, another cause of recurrent vaginitis
is an infected partner who needs to be treated. Prolonged treatment is needed to prevent relapses; treatment should be given based on the clinical situation up to six months at intervals. Meanwhile, please try to improve the general condition by improving protein intake, using plenty of fresh fruit, fresh vegetables and nutritional supplements of vitamins and minerals
. Hope this helps.
