Ors.. 4-5lt per day .maintain urine output ..1ml /kg/hr..metrogyl is safe ...
Thank you doctor
Metronidazole is category B drug in pregnancy Fluroquinolones shd be avoided in view of cartilage and bone damage Azithromycin is one safe drug Rest Probiotics and Fluid
Metronidalzole is not safe at urogenital problem..because for that cases we use higher dose ..but for gastrointestinal problem..there are many studies that this is safer..we can use at low dosage..200mg three times even .
