For Tuberculosis, Latent "I was terrified about taking isoniazid due to all of the problems these other people were having while on this medication. I need to take this medication for latent tuberculosis since I’m starting a medical program and need to have the TB cleared from my body before I can start clinicals for school. I’ve been taking this medication for two whole months now. 300 mg of isoniazid daily with a 25 mg tablet of vitamin B6. I have had no symptoms whatsoever. I’ve never had an issue with antibiotics ever though. I feel normal. Not experiencing symptoms of liver failure either, but I’m going to get my liver enzyme levels checked just in case. I’m just posting this to show people who are afraid that you may be fine like I am. I have 4 more months of this medication."

For Tuberculosis, Latent "I had to take Isoniazid 300 mg per day for a positive skin test upon starting treatment with Humira for psoriatic arthritis. I had no side effects except I seemed a little more edgy; I too was a little concerned at first about it being rough on your liver, but they monitored it every two months. The results always came back fine (of course, I did give up alcohol for the 9-month treatment), so my experience was not bad, and I would say not to be overly concerned about liver failure because I put my liver through some real punishment in my younger party years and everything worked out. I am glad it's over; a 9-month treatment was long, but you get used to it after a while."

For Tuberculosis, Latent "For those who just found out they have latent TB, the treatment is tedious, but I have remained very healthy and have no serious complications. I have taken this medication, 300 mg once daily for almost 9 months. Only main issue is it totally messes up a woman's cycle. My doc put me on 50 mg of Vit B6 to prevent nerve damage. I take the Vit. B every day. My doc checks my liver and other blood levels every month to make sure I do not damage my liver. I take 50 mg of trazodone for sleep, and it doesn't seem to interact weird with the isoniazid. It's just a pain to have to remember every day, but you get used to it."
