Question: Have taken 4 weekly doses of 12 week regiment of Prifton and Isoniazid for latent TB. Has severe allergic reaction of fever, chills and rash on arms and legs, Considering stopping the drugs. However I wonder if the 4 doses was enough to "activate" the bacteria so that when I stop the drugs I would now have active TB. I would want to still be in the latent TB stage. I have been told I should still be latent but would like to confirm. I have no symptoms at present.

I am taking isoniazid for exposure to TB. About 2 weeks ago I ate several slices of pizza and a few wings. In 2 days I had what I thought was salmonella. Bloating, nausea, vomitting, and frequent diarrhea, abdominal pain - the works. My doctor prescribed cipro - forget the dose, but took it BID for 4 days, full course with prompt resolution of all symptoms. Several days after finishing the cipro, my symptoms started to return - but I had another 2 slices of pizza before the symptoms came back. I had the pizza on Friday and it's now Tuesday, still having some diarrhea, bloating, gas, abdominal pain, fatigue - just not as severe as the first bout. I am however taking a dicloxacillin/amoxicillin combo that I keep stocked for emergencies. I am a traveling consultant = and nothing worse than being on the road with an infection and having to find a local doc to get things figured out. So - question is - could this be a reaction to cheese on the pizza (aged cheese and pepperoni) with the isoniazid, or a recurrance of the salmonella?
