I am not a patient but i have c-diff. am on 500 mg metronidazole every 12 hrs for 5 days and still sick. how long before i can feel better. how long ?

C diff : Based on best evidence the dosing for c diff if your pretty symptomatic should be every six to eight hours. Also you should be taking probiotics about three times a day, again good evidence supports this. Usually it takes 5-7 days for symptoms to subside with adequate treatment. How ever can last up to 2 weeks. If not improved or getting worse see your doctor again to go over treatment options
