I recently went to the hospital and was diagnosed with colitis. They gave me a prescription for some intestinal antibiotics but also prescribed me Flagyl. I'm thinking it's a possibility they did it because I had BV as well. However, I read the normal treatment for BV is 2 grams of Flagyl, but my doctor prescribed me 500mg to take 3x a day for 1 week. That's 10,500 grams! Is this even safe??
