Reviews for Isoniazid
For Tuberculosis, Latent: "It's my third month treatment for latent TB. My ALT (liver enzyme) increased already three times than normal at 100. I experience chills, fever, joint pain, tingling on my hands and feet, nausea. I'm very worried about my liver damage too. My doctor told me to get blood work every week and if I start vomiting to stop medication and call her right away. I'm so upset if I stop medication I might get active TB at one moment in life and I would need more medication, if I continue, I don't feel well and I don't know what effect would have, in time on my body and especially on my liver. Maybe I should have refused the treatment in first place. Life sucks. :( ps. I take every day one tablet of Isoniazid 300mg with vitamin B6 25mg"

For Tuberculosis, Latent: "I was given Isoniazid 300mg and Pyridoxine 25mg to be taken daily. My liver enzymes rose as predicted by my doctor, but was assured they would return to normal after treatment stopped. I took the medication for four months. Never touched any alcohol and stayed clear of any foods listed that might cause side effects. I had a few instances of severe stomach cramps (similar to the pain experienced with gastro enteritis) and was so weak I almost collapsed. I felt unwell most of the time and decided to stop taking the meds after four months. Six months has now passed , my liver has returned to normal but my doctor has advised me to begin the treatment again for five more months. I am undecided as to if I should or not."

For Tuberculosis, Latent: "I hate that I started this medication. I was told by the doctor that having Latent TB there was a 10% chance of developing active one day on life (most likely at older age). But taking it damages my body now (100% chance). I'm not sure how the pharmaceutical industry is behind this to sell drugs, I truly doubt the necessity. Besides if you miss doses or stop the treatment you will be creating a super TB bacteria. I've being taking for 2 months, felt depressed and sleepy, most of all angry to be trapped on this when I was a healthy strong person. I feel like I trusted the doctor and now I regret. I'm not sure if my view is correct, but I strongly advise someone educating themselves a lot before starting starting. No way back."

For Tuberculosis, Latent: "Almost completed with month 7 of 9 of the INH. Overall the experience has been good. I get my liver enzymes checked every three months through a blood test with no issues. I do drink alcohol but pay much more attention to moderation than I felt like I needed to before. I am careful about taking it daily. I have stuck to the routine of taking it on an empty stomach (recommended) and then eating 30-40 minutes. No change in emotions. One complaint which applies to women is I did experience what I thought was spotting between my periods however it appeared to only happen when I used the washroom and it was more orange than red. After several tests with the gynecologist it was determined it was the INH. If this occurs see an GYN in case!"

For Tuberculosis, Latent: "4 1/2 Months into taking INH. Just got back from the doctor and my liver enzyme levels are over twice the normal! I Have only starting feeling the side effects in the last couple of weeks. slight liver pain, yellow urine, vomiting etc. I think for the most part though I did it to myself as I did drink heavily 3 times over the last few months (I'm a 21 year old male). Going for check ups regularly to finish out the 6 months. If liver enzymes go above 3 times the norm, advise is to stop medication."

For Tuberculosis, Latent: "Been on Isoniazid and Pyridoxine for 5 months now for Latent TB and have noticed that I've become much more nervous especially when I'm presenting to a crowd. I've never had issues like this and been a good orator. Lately I get choked up and have performance anxiety!!! Can't wait to stop this medication!"

For Tuberculosis, Latent: "Overall I'm sure this medication is very effective but after taking it a week I started getting nausea and stomach pain, especially after I ate. I'm sure some of this has to do with the fact I ate cheese sometime. As you have to be careful not to have foods high in Tyrasine. But I started to have general stomach pain, cramping and tenderness. So my doctor said today that I have to stop taking the meds. Now I'm going to the infectious disease specialist."

For Tuberculosis, Latent: "I've been on the isoniazid for almost one month and I'm not sure I will be able to continue. I'm experiencing bad headaches nearly every day. Before going on the drug, I took Tylenol every 6 hours for arthritis pain. Now I have had to stop the tylenol. I have Crohn's disease so I can't take any NSAIDS. That leaves me no options for my headaches. Not sure I can deal with this for 9months. After one week my liver enzymes have already increased by 7. Pretty stressed out about this whole thing. I tested positive for latent TB when waiting to start Humira for my Rheumatoid Arthritis. Now I can't take anything for my pain until I'm treated for the TB for 9months. Life sucks."

For Tuberculosis, Latent: "For those who just found out they have LATENT TB, the treatment is tedius 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 be on 50mg 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 everyday but you get use to it."

For Tuberculosis, Latent: "I had to take Isoniazid 300 mg per day for positive skin test upon starting treatment with Humira for Psoriatic Arthritis. I had no side effects accept 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, Active: "I am on my 5-th month of Tuberculosis treatment. Taking Isoniazid with combination of Rimfampin and Vit. B6. It is very difficult time for me, because since the beginning of taking this medication I'm experiencing very strong mood changes, I'm very nervous and anxious. Can't sleep at night. I never read about the anxiety side effects of Isoniazid, but I have one since the start of the treatment. No gastrointestinal side effects though."

For Tuberculosis, Active: "I have just started the medicines for TB and already I'm not well. The rifampin gave me a major allergic reaction and had to be stopped. Now on Isoniazid; pyrazinamide and ethambutol and vitamin B6 --- major stomach problems and diarrhea. "

For Tuberculosis, Latent: "I'm currently on this medication plus vitamin B6 for positive TB skin test. I've been taking it for about 4 months now. I'm scared to death. I wonder if I will be able to go through these 9 months without serious side effects like liver damage. Haven't experienced any side effects so far. I seem okay. 5 months to go. Hopefully nothing serious happens. I'm so moody lately. My coworkers say I now have an attitude."

For Tuberculosis, Prophylaxis: "I'm still here, so I guess it worked - but it was a rough, horribly rough 9 months - it helped that I was already on medical leave (and that the hospital took responsibility for the exposure) - Isoniazid is literally a sort of (failed) anti-depressant that works against TB, but is also pretty harsh on the liver, so I had to take Vitamin B6 for 9 months too. I was pretty moody, crazy, aggressive - not my normal self... it was a long 9 months. I can't understate how mood altering this medicine was - not in a good way. I was embarrassed to talk about it, which made my behavior all the more odd to my friends and co-workers, but once I explained it, I got some support - anyhow, I wish I had done that from the start. On the plus side, I'm still here!"
