Transfusion reaction. An equivocal positive test or poorly documented one can and should be repeated. A chest x-ray and, if cough is productive, sputum culture should be done on a regular, periodic basis. Once positive, a repeat tuberculin test that is positive is meaningless.
Yours was a violent reaction to isoniazid (INH). Indeed you should not take INH again, but there are alternatives. Glad you survived this severe drug reaction. Before you and your doctor resort to an alternative, you must be sure that there is no evidence of active tuberculosis, as that would determine the optimum therapeutic regimen.
I'm scared and also there are medications that will activate my TB bug as per my doctor but no one has told me what to do. My breathing is getting worse and my doc will want me in the hospital. I'm afraid their may be mistakes in meds. Which meds should I stay off, and if I can't because of lung disease, what do you suggest?
Thanks.
