Raised Liver Enzymes (SGPT/SGOT) — on Targeted Therapy
A raised SGPT or SGOT on your blood test during targeted therapy is common, but the action it needs depends entirely on how high it is and whether you have symptoms. Most mild rises are monitored closely without stopping treatment. Some require a dose pause. A few are a same-day emergency.

- Common, not always dangerous — Mild enzyme rises happen with many targeted therapies and often settle without any change to your dose.
- Caught by blood tests before symptoms — Significant liver changes usually show up in your results before you feel anything — this is why regular monitoring matters.
- Symptoms change the urgency — Yellowing skin, dark urine, or right-sided abdominal pain alongside any rise means call your team today, not at your next appointment.
- Supplements add to the liver's load — Many herbal and traditional preparations are processed by the liver and can push enzyme levels higher. Tell your team everything you take.

A raised SGPT or SGOT during targeted therapy means your liver is under more stress than usual from processing the drug. This is common and often mild — many patients are monitored closely without any change to treatment. The level, whether it is rising or stable, and whether you have any symptoms are what your oncologist uses to decide the next step.
If a symptom below applies to you, do not wait for a callback. Call 1800-202-8726 or go to your nearest emergency department.
Is a raised SGPT or SGOT on targeted therapy dangerous?
Your liver processes targeted therapy drugs. A raised enzyme level on your blood test measures how much effort that is taking. A mild rise is a signal worth watching — it does not mean something has gone seriously wrong.
Most targeted therapies carry a known risk of liver enzyme elevation. Your team checks for it regularly because catching a rise early means they can act before it becomes a problem.
What matters most is how high the level is, whether it is rising or holding steady between tests, and whether you have any symptoms. A raised result with no symptoms means contacting your nurse team — not rushing to hospital.
What can you do at home while you wait for guidance?
Stop alcohol completely until your team tells you it is safe again. Alcohol and targeted therapy drugs are both processed by the liver. The combination puts significantly more strain on it than either would alone.
Avoid paracetamol and ibuprofen unless your oncology team has specifically cleared them for you. Both add to the load your liver is already carrying. Many cold and flu tablets contain paracetamol — check the label of anything you take.
Tell your team about every supplement, herbal remedy, and traditional preparation you are taking — including things you have used for years. Many widely used preparations are metabolised by the liver and can drive enzyme levels higher on their own. Your team needs a complete picture of what your liver is processing.

Tell your team all of this at your next contact
- Every supplement, herbal remedy, or traditional medicine you are taking — include how much and how often
- Any alcohol consumed since your last blood test
- Whether your skin or the whites of your eyes have looked yellow, even briefly
- Whether your urine has appeared darker than usual
- Any pain or aching in the upper right side of your abdomen
- Fatigue that came on suddenly rather than building gradually
What does your enzyme level actually mean?
| Level | What the blood test shows | What usually happens next |
|---|---|---|
| Mild | Slightly above the laboratory's upper limit of normal | Closer monitoring; treatment typically continues unchanged |
| Moderate | Clearly above the upper limit of normal | Your team may pause your dose and recheck more frequently |
| Severe | Significantly above the upper limit of normal | Treatment is usually stopped; specialist liver assessment needed |
| Any level with symptoms | Jaundice, dark urine, or severe abdominal pain alongside any rise | Same-day emergency assessment — see the red flags above |
| Typically detected | Most often in the first weeks to months of treatment, but can occur at any point | Routine blood tests catch this before symptoms appear |
Did you know?
Liver enzyme monitoring is one of the primary reasons targeted therapy can be used safely over many months.
When elevations are caught early through routine blood tests, most are managed with a temporary dose pause — and many patients restart the same treatment once levels return to normal. It is the delayed or unreported rise that becomes dangerous.

Common questions
Frequently asked questions
My SGPT is raised but I feel completely fine. Do I still need to report it?
Yes. Feeling well does not mean the liver is coping well — significant enzyme changes often appear in blood results before any symptoms develop, and waiting until you feel something is exactly the delay that turns a manageable situation into a serious one. If your latest blood test showed a raised result, contact your nurse team the same day and let them tell you whether it needs urgent action or closer monitoring. The call takes minutes and takes the decision off you.
Will my targeted therapy have to stop because of raised liver enzymes?
Not necessarily. Whether treatment is paused, dose-reduced, or continued depends on how high the enzyme level is and whether it is climbing between tests. NCCN and ASCO guidance outlines a graded approach: mild rises are usually monitored while treatment continues, moderate rises may prompt a temporary pause, and severe rises typically require treatment to stop until the liver recovers. Many patients restart the same drug once levels normalise. Reporting early is what keeps the milder options available.
Can I take paracetamol for pain while my liver enzymes are raised?
Do not take paracetamol — or ibuprofen — without asking your oncology team first. Both are processed by the liver, and taking them while your liver is already under strain adds to the load. The same applies to combination cold and flu tablets, many of which contain paracetamol. Your team can advise on the safest option for your pain. If you have already taken some before reading this, tell them at your next contact — it helps them interpret your next blood test correctly.
Can herbal or traditional medicines cause my liver enzymes to rise?
Yes, and this is much more common than most people expect. A number of widely used herbal preparations — including some taken routinely in India for general health — are metabolised by the liver and are known to raise enzyme levels on their own. The combination with a targeted therapy drug can push levels higher than either would alone. Your team is not asking you to stop anything without reason. They need a complete picture of what your liver is processing so they can read your results correctly. List everything, including powders, tonics, and teas.
How long does it take for liver enzymes to come down after a dose pause?
It varies depending on how high the levels were and how your liver responds. Mild elevations that prompted a short pause often settle within a few weeks. More significant rises can take longer, and your team will recheck at intervals they set based on your pattern rather than at a fixed date. The goal is to wait until levels return to a safe range before deciding whether to restart at the same dose, restart lower, or consider a different treatment. Your individual response guides the timing — there is no single answer that applies to everyone.
