My husband and I were looking forward to starting a family when I had a positive TB skin test. We had to postpone our plans once my provider put me on INH therapy (9 months course) for latent TB.
I have three more months left of INH therapy and I started taking prenatal vitamins and folic acid a month and a half ago. How long after INH therapy is finished should we wait until we can try to conceive? When should I stop taking my birth control pills?
INH is excreted in urine within hours of discontinuation. Once you are off it, I'd suggest finishing your pill pack or to be extra-safe, take one more pill pack.
You should also have your liver function tested one last time to make sure it's normal. Then have fun!
But I have not seen your specific chart, so do confirm what I am saying with your own provider.
