Darlene Posted March 9, 2011 Report Share Posted March 9, 2011 Has anyone taken isoniazid because of a positive tb skin test? If so, did you have any side effects? The Dr. called me today and said she was gonna start me on isoniazid, but wanted me to come in and talk with her first. She said something about choices. I don't understand why it's not as simple as calling in a prescription. I do have POTS, and am hoping this med does not make me ill. I am finally able to work after 5 years of being sick. I am just curious, how do they even know if I have latent tb? Isn't there a blood test they can do? Quote Link to comment Share on other sites More sharing options...
