Anti-TB medicines and the liver: jaundice, damage and recovery | CION Cancer Clinics
TB tablets can irritate the liver and cause jaundice, and in India they are one of the most common reasons for it. Most people never have a problem, and when they do the liver usually recovers once the doctor adjusts treatment. This page explains who is more at risk, the warning signs, when to go to hospital the same day, and how TB treatment is safely restarted. At CION Cancer Clinics, our team goes through your scan, blood test and biopsy reports with you and plans the next step.

The short answer
Can TB medicines damage the liver and cause jaundice?
Yes. The standard TB tablets are one of the most common reasons for liver injury and jaundice in India. Most people who take them have no liver trouble at all, and in those who do, the liver usually recovers once the doctor pauses or adjusts the treatment.
The important part is what you do next. Yellow eyes, dark urine, nausea or vomiting while on TB treatment should be reported to the TB doctor quickly, and the tablets should never be stopped or restarted on your own. Stopping without a plan can let the TB come back in a form that is harder to treat.
Why this page is on a liver cancer site
Two confusions happen here. A person on TB treatment who develops jaundice is sometimes frightened into thinking the liver has cancer, when the tablets are the cause. And TB of the liver itself can look like a tumour on a scan, so a person can be treated for one when they have the other. Our pages on TB of the liver and why liver TB and cancer look alike cover that second problem.
This page is about liver injury caused by TB medicines. It does not tell you whether a spot on your liver is TB or cancer.Who is more likely
Who is more likely to get liver problems on TB treatment?
Anyone can, but doctors watch some people more closely from the start.
People with a liver that is already unwell
Hepatitis B or C, fatty liver, cirrhosis or regular alcohol use all leave less room for the liver to cope. The TB doctor may check the liver tests more often, or choose a gentler combination.
Older adults and people who are underweight
Age and poor nutrition both make the liver more sensitive. In India many people with TB have lost weight before diagnosis, which is one reason liver checks matter.
People taking other medicines too
Painkillers, seizure medicines, HIV treatment and herbal liver tonics can all add to the load. Tell the TB doctor about every one, including the ones you think do not count.
People with cancer on treatment
Chemotherapy and some targeted drugs also pass through the liver. When TB and cancer are treated at the same time, the TB doctor and the oncologist need to plan together.
The medicines usually involved
- Isoniazid
- Rifampicin
- Pyrazinamide

When not to wait
Go to hospital today if a person on TB treatment has yellow eyes or skin together with repeated vomiting, fever, new confusion or drowsiness, bleeding, or severe pain in the abdomen. Take the TB card and all the tablet strips with you. If there is only dark urine, mild nausea or a loss of appetite, contact the TB doctor or the TB centre within the next day or two. Do not stop or restart the tablets on your own.
What the doctor does next
What happens if TB medicines affect your liver?
-
Blood tests to confirm it
Liver tests, including enzymes and bilirubin, are compared with the results from before TB treatment began. Tests for hepatitis viruses are often added, because a viral hepatitis can look exactly the same.
-
A pause in the medicines that affect the liver
If the injury is significant, the TB doctor usually pauses the tablets that are hardest on the liver. Where the TB is serious, other TB medicines that are gentler on the liver may be used in the meantime.
-
Waiting for the liver to settle
The tests are repeated until they come back down. For most people this happens over a few weeks, and the jaundice fades as it does.
-
Restarting, one medicine at a time
The tablets are usually brought back one by one, with blood tests in between. This shows which medicine caused the problem, so only that one is left out.
-
Finishing the full course
The course may be changed or made longer. Finishing it matters as much as protecting the liver, because unfinished treatment is how drug-resistant TB develops.

On your report
What do the words on a TB liver report mean?
- ALT and AST
- Enzymes that leak out of irritated liver cells. A rise shows the liver is being strained. It does not show how well the liver is working.
- Bilirubin
- The yellow pigment the liver clears. When it rises, eyes and skin turn yellow and urine turns dark.
- Drug-induced hepatitis
- Inflammation of the liver caused by a medicine. With TB tablets it is often written as ATT-induced hepatitis, ATT meaning anti-tubercular treatment.
- Rechallenge
- The careful restarting of TB medicines one at a time once the liver has settled.
- Baseline LFT
- The liver function test done before TB treatment starts, used later to judge whether anything has changed.
Commonly believed
What families often believe about TB tablets and jaundice
"The jaundice means the TB has spread to the liver."
Usually it does not. Jaundice during TB treatment is far more often a reaction to the tablets. TB of the liver is a different problem, found on a scan, and it is less common.
"Once the tablets damaged the liver, TB cannot be treated any more."
TB can still be treated in almost everyone. The doctor adjusts the combination, restarts carefully and, if needed, uses medicines that are gentler on the liver.
"A liver tonic alongside TB tablets will keep the liver safe."
No tonic has been shown to prevent liver injury from TB medicines. Some herbal products can add their own strain on the liver. If you want to take one, ask the TB doctor first, and you will not be judged for asking.
"Jaundice on TB treatment can turn into liver cancer."
An episode of drug-induced hepatitis that settles is not known to cause liver cancer. If the tests do not settle, or a scan shows a lump, the doctor will look for another cause.
Being straight with you
What this page cannot tell you
It cannot tell you whether your jaundice is caused by TB tablets, by a hepatitis virus or by something else. It cannot tell you which of your tablets to pause, or when to restart. Those decisions belong to the TB doctor who knows your TB, your weight and your earlier reports. The wider page on drug-induced liver injury covers other medicines.
Who this does not apply to
If you have a lump or a spot on the liver on a scan, this page is not about you. A spot needs its own work-up, which may include a biopsy, and TB and cancer must be told apart properly. If you have hepatitis B, the TB doctor and a liver specialist should plan together; see reading a hepatitis B report.
Where CION fits
CION does not treat TB. When a cancer patient also needs TB treatment, the CION oncology team works with the TB doctor on timing and on liver checks, and coordinates a hepatologist's opinion through partner hospitals when needed.
Questions we are asked
Common questions about TB medicines and the liver
How soon does liver damage from TB tablets show up?
Most liver reactions appear in the first couple of months of treatment, though they can happen later. That is why many TB doctors check the liver tests at the start and again if any symptoms appear. Report nausea, vomiting, yellow eyes or dark urine at any stage of the course.
Should I stop my TB tablets if my eyes turn yellow?
Contact the TB doctor or TB centre straight away and follow their instructions. Do not stop or restart on your own. If the yellow eyes come with vomiting, fever, confusion or bleeding, go to hospital today and take your tablets and TB card with you.
Will my liver go back to normal?
In most people, yes. Once the medicines that caused the problem are paused, the liver tests usually come back down over a few weeks. A small number of people have a severe reaction that needs hospital care, which is why warning signs must not be ignored.
Can I still finish my TB treatment after jaundice?
Almost always. The doctor restarts the tablets one at a time, finds the one that caused the problem and builds a course without it. The course may be longer. Finishing it is essential, because half-treated TB can return and become resistant.
Can I drink alcohol during TB treatment?
It is safest not to. Alcohol and TB medicines both strain the liver. If you drink regularly, tell the TB doctor honestly. It changes how closely your liver is watched, and nobody will refuse you treatment for saying so.
I have hepatitis B. Is TB treatment safe for me?
TB treatment is still needed and can be given safely, but the risk of a liver reaction is higher. Your liver tests will be checked more often, and some people also need hepatitis B medicine. A hepatologist or physician should be part of the plan.
Could my jaundice be cancer instead of the tablets?
It is uncommon, but it is why doctors check rather than assume. An ultrasound helps if the jaundice does not settle after the tablets are paused, or if there is weight loss, a lump or itching with pale stools. Only those tests can answer the question.
I am on cancer treatment and need TB tablets. What now?
Tell your oncologist before starting the TB tablets. Some cancer drugs and TB medicines affect each other or both strain the liver, so timing and checks may change. Call the CION helpline if you are unsure who should coordinate the two plans.
