For Anal Fissure and Fistula "Had fissure for 18 months due to chronic idiopathic constipation. I used to bleed every time I had a bowel motion and had severe pain. I was on this before, but it didn't work, so trying once more, otherwise, I'll need a Botox injection. Anyway, I've been on it for over a week, and yes, had a slight headache and been very dizzy. I still am getting pain, but so far no bleeding! I will continue for 7-11 weeks, fingers crossed for y'all. I'm 5'2" and 100 lbs. 24. BTW."

For Anal Fissure and Fistula "I have gone to my new surgeon. She had done a colonoscopy on me. After that, I went to the follow-up. She said I have a really bad fissure tear with hemorrhoids, so she gave me this medicine. She said it will make you dizzy, have headaches, or even fall down. I am 24 years old, I have had this pain for almost 2-3 years with blood in my stool. She even put me on a high-fiber diet. I am now taking stool softeners and Metamucil. So, she said to start with a pea size, then an inch pea size 1-3 times a day. If you can, start with 1 inch, 12 hours a day, then do another pea size if you took a shower or a bowel movement. Side effects I had: weakness, headaches, feeling a little dizzy. Let's see the results when I go back to the surgeon, I hope for no surgery. But once I got used to it, I barely had headaches. Mild, after a month and a half of using, cannot remember."

For Anal Fissure and Fistula "I am just now starting this medication. I took it for the first time last night and got horribly dizzy and felt terrible. I had a headache, nausea, all that. I ended up passing out and feeling normal when I got up the next day. I then tried it again, but in a smaller dose today, and so far, I have a headache, but I don’t feel as bad as before. I have had an anal fissure for months now that bleeds every time I have a bowel motion. I am on stool softeners such as Colace and Miralax, and they seem to do the job to get me going. This all started from becoming super constipated a few months ago and forcing myself to poop. I really hope this medication works, as I am so sick of bleeding when I poop and tired of being so scared of it. I have had poops where I have almost no blood, and I have had poops where I have a lot and it’s all over the poop itself (usually after a rectal exam). I am running out of hope and so sick of feeling this sense of worry and anxiety. Any tips?"
