Something like that I am not sure the spelling of the sulfa part is correct it is not in front of me. My Doc has given this to me for bladder infection. Can I tell you it is gone and I do not know what this drug does along with Coq10 I forgot I started that right after I stopped burning. Something is making me feel almost normal. I have more energy I have even halved my tablets of the sulfa just to make them last longer. They are white oblong with a v on one side and numbers on the other. Like b6 or 68. What I am trying to say is the days I have not taking this drug I feel like I have chronic fatigue and fibro. Now I do not know what is going on and know this antibiotic. I would like to take it forever and I have walked is it working right with the other meds I take. Which is wellbutrin and one Hbp pill. What could be doing this?? It is not my imagination. I will go a couple of day and I will hurt and have no energy. Got up this morning popped half and multivitamin malic acid and coq10. Then hbp med and wellbutrin sr 150 mg. I know there are some hightly intelligent people on this board. I am sure my Doc will think I am crazy if I tell him this. I drink water taking this like the package. It is a sulfa drug right. Is it possible I could take this long term?? The only other antibiotics I have taken were just a couple in the past 2 years when the sinus infections would not go away. All you smarter that me people tell me what is going on. plus I am getting rid of excess water. I always envied people, now this is crazy that were in other stalls and were urinating like a goat and I am trying to push it out. That has been me my whole life and I have had plenty of cultures and all the crap urologist do. Nothing showed up except sometime excess protein. I have more energy taking this and less pain. I want to get up and go. This is very confusing let me know what you think Hensue So what is the cosensus here???
