My sister have been feeling some burning sensation while peeing, and some itching since 2.5 weeks . She has been taking D mannose syrup called tracfree KM , the symptoms are better but still she is facing burning sensation during peeing . As it's been more than 2 weeks along with intake of the syrup, is there any precautions that should be taken for it. Any antibiotics that can be recommended. And what is the correct way to intake the syrup or any antibiotics that you prescribe?. And how much intake of the syrup she should maintain in a day?
