I'm a PPD converter too. I was never told which pt I was exposed to, but I am quite certain of who it was and it was significant close-contact.
Since I had done a little infection control, I had tracked a case of a pt who was placed on the prophylactic rx for an exposure. I will never forget it, b/c he was so orange, he glowed in the dark. It was from the INH.
These drugs are not to be taken lightly. The last recommendation by the CDC is caution if over age 35 for prophylaxis. I was 35 when it happened, so I was on the fence about it. I was freaked out too. I spoke w an ID guy I respect a great deal, and he said even if I did get the rx, the bacillus is not completely erradicated from your body, it will still be dormant in your cells, and if you should ever become malnourished, or immunosuppressed, you can develop TB. There is NO GUARANTEE against getting TB in the future, even if you take the prophylaxis.
So, I opted not to take the meds. I got a CXR yearly x 2 years, then q 2 years. MY doc still does them yearly. I am fine, and it was 4 years ago. I am finally to the point that I even forgot to tell the pulmonologist I saw the other day about it on my history.
Take deep breaths. You are going to be OK. Talk with a doc you trust, check out the CDC recommendations www.cdc.gov
, and make an informed decision. You're going to be OK.
