Hi
I am 32 years old man. 3 years back I was suffering from typhoid fever for one and half months. I had taken Azythromycine antibiotic at that time. When the Typhoid fever was gone, I stopped taking this antibiotic. Since then my stools became very loose. 6 months before I caught tuberculosis. Now I am taking Akurit 4 and my health is recovering well. My weight was 55 KG when I was diagnosed with TB. Now I am 68 KG. I am still taking TB drugs. My height is 5 feet 10 inches. But my stools are still loose. I feel sometimes a tendency like vomiting. I told this to my doctor, he prescribed Widal test which came positive. (Typhi O – 1:320, Typhi H- 1:40, Typhi AH- 1:20, Typhi BH- 1:20). The doctor prescribed me Levofloxacin 10 tablets. When I taken Levofloxacin according to the prescribed dose, the vomiting gone away. But my stools are still very loose. I am also taking probiotics and prebiotics also as prescribed by my doctor. I again told the doctor about loose stools. He prescribed Rifaximine (RIFAGUT) antibiotic, 10 tablets and some probiotic combination (VSL#3 and Lifelac capsules). I have taken all the dose of Rifaximine. But there seems no use. What can I do for getting rid of loose stools? Please prescribe me some medicine as soon as possible. I am very nervous. Please help me.
