As I mentionned on a previous post, my son is taking metronidazole (Flagyl). The doctor prescribe it for 2 weeks, which he will finish tomorrow and it is renewable 2 times. Here is my question, do we have to renew it and continu the Flagyl? We left messages with the G.I. doctor's secretary but no return phone call. Do we wait and see if the pain comes back and then refill and take another 2 weeks? Can anyone who has taken it in the past give me informations as to how they took it. He is doing pretty good and I just don't want to stop the Flagyl if it's supposed to be continued and then he gets pain again. On the other hand, I figure that if the doctor gave it for 2 weeks, it's because he wants a break in between otherwise he would have prescribed it for 6 weeks. I don't know what to do? Can you please help. Thank you!
