Generic and biosimilar versions of liver cancer medicines: what to know | CION Cancer Clinics
Generic sorafenib and lenvatinib tablets and biosimilar bevacizumab infusions are approved in India and widely used, and they usually cost much less than the original brands. The choice of medicine comes first; the version comes second. This page explains what generic and biosimilar mean, which liver cancer medicines have cheaper versions, and how to choose one safely with your oncologist. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
Are generic sorafenib and biosimilar bevacizumab safe to use?
Yes, when they come from a maker your oncologist trusts and are approved by the Indian drug regulator. Generic sorafenib and lenvatinib tablets, and biosimilar bevacizumab infusions, are used every day in Indian cancer care, and they usually cost much less than the original brands.
This page is about medicines for hepatocellular carcinoma (HCC), the cancer that starts in the liver itself. If your liver cancer spread from the bowel or elsewhere, the medicines are different, and colorectal cancer in the liver is covered under colon cancer.
Why India has so many versions
India has a large medicine industry and patent rules that allow cheaper versions once a patent ends or is overridden. Sorafenib is a well-known example: India allowed an Indian company to make it under a compulsory licence, which opened the way for affordable versions. For a family paying month after month, that difference is often what keeps treatment going.
What does not change
The decision about which medicine you need comes first. A generic or a biosimilar changes the price of a medicine, not whether it suits your liver or your cancer. Your oncologist chooses the medicine, then helps you choose the version.
Never switch brands on your own or buy from an unknown seller online. Ask your oncologist first.The three words you will hear
Original brand, generic, biosimilar: what is the difference?
Pharmacies and relatives often use these words loosely. They mean quite different things.
Original brand
The medicine as first developed and tested in the large trials. It is usually the most expensive version, because the maker is recovering the cost of research.
Generic
A copy of a tablet medicine made by chemistry. The active ingredient is the same molecule as the original. Sorafenib, lenvatinib, regorafenib and cabozantinib are tablets of this kind.
What may differ
- The colour, shape and packet
- The inactive fillers in the tablet
- The price
Biosimilar
A version of a medicine made in living cells, such as an antibody given as an infusion. It cannot be an exact copy, because living cells never make two identical batches. It must be shown to work and behave like the original before approval.
Which liver cancer medicines have them
Bevacizumab has several biosimilars in India. Atezolizumab, durvalumab and tremelimumab are newer, and at the time of writing cheaper versions are limited or not available. Ask your oncologist what can be sourced now.
Not sure whether this applies to you?
Ask an oncologistChoosing a version
How do I choose a generic or biosimilar safely?
Agree the medicine first
Your oncologist and the tumour board decide which medicine suits your liver, your cancer and your fitness. Only then talk about versions.
Ask which makers they use
Oncologists know which makers supply reliably and which they have used before. Ask for two or three names you can price.
Buy from a licensed pharmacy
Use a hospital pharmacy or a licensed chemist with a bill. Avoid unknown online sellers, loose strips and medicines brought back without a prescription.
Check your insurer or scheme
Some policies name the brand on the claim. Ask whether changing version affects cover. Read about insurance and biosimilars.
Stay with one version if you can
Changing brand mid-treatment is sometimes fine, but tell your team each time so side effects are tracked properly.
On your prescription
What do the words on the bill and the box mean?
- Molecule or generic name
- The name of the medicine itself, such as sorafenib. It stays the same whichever company makes it.
- Brand name
- The name a company gives its version. One molecule can be sold under many brand names in India.
- Biological medicine
- A medicine made in living cells, usually given by infusion. Bevacizumab and atezolizumab are biological medicines.
- Reference product
- The original medicine a biosimilar is compared against when it is tested.
- CDSCO
- The Central Drugs Standard Control Organisation, India's drug regulator. It approves medicines, including generics and biosimilars, before sale.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
Did you know
Bevacizumab, generic or original, needs an endoscopy first if you have cirrhosis, because it can make bleeding from swollen veins in the food pipe more likely. A cheaper version does not change that check. Read why you need an endoscopy before bevacizumab.
Commonly believed
Is a cheaper version a weaker medicine?
"Cheaper means it has less medicine in it."
An approved generic contains the same active ingredient as the original. The lower price comes from not repeating years of research, not from a smaller amount. The sorafenib myths page covers generic quality in more detail.
"A biosimilar is just an untested copy."
A biosimilar has to be compared closely with the original in the laboratory and in people before approval. It is not identical, because no biological medicine is, but it must behave the same way in practice.
"Imported brands are always safer."
Safety depends on the maker's quality and the supply chain, not on the country printed on the box. A licensed Indian maker your oncologist knows is a sound choice.
"If side effects change, the generic is fake."
Side effects can change for many reasons, including your liver function. Tell your team. Do not stop or switch the medicine on your own.
Being straight with you
What this page cannot tell you
It cannot tell you which brand to buy, or whether a particular batch from a particular seller is genuine. Your oncologist and a licensed pharmacy are the people to ask. It also cannot give prices, which change often. The page on the monthly cost of each systemic option explains how to get a written estimate.
Who this does not suit
A cheaper version does not make a medicine suitable for someone it would not otherwise suit. If your liver function is weak, if you have had a liver transplant, or if bleeding risk rules out bevacizumab, the version is not the question. For some people, supportive care without these medicines is the kinder plan, and a cheaper option should not change that decision.
It cannot predict what will be available
New generics and biosimilars reach India every year, and some disappear. What is true today may change. Ask at each stage of treatment.

Common questions about generic and biosimilar liver cancer medicines
Is generic sorafenib as good as the original?
An approved generic contains the same active ingredient and is expected to work the same way. Indian generics of sorafenib have been in use for years. Buy from a licensed pharmacy, use a maker your oncologist is happy with, and report any new side effect.
Is there a generic lenvatinib in India?
Yes, several Indian companies sell lenvatinib. Prices differ between makers and pharmacies. The lenvatinib price page covers brand and generic options. Ask your oncologist which makers they trust before you buy.
Can biosimilar bevacizumab be used with atezolizumab?
Many oncologists in India do pair a biosimilar bevacizumab with atezolizumab to lower the cost. Whether it suits you is a decision for your oncologist. The biosimilar bevacizumab page explains more.
Is there a cheaper atezolizumab?
At the time of writing, cheaper versions of atezolizumab are not widely available in India. This may change. Ask your oncologist what can be sourced now, and ask about the drug access programmes some makers run.
Can I switch to a biosimilar halfway through treatment?
Often yes, but only with your oncologist's agreement. Tell the team the exact version you are switching to, so any change in side effects is linked to the right medicine. Do not alternate between brands from month to month without telling anyone.
Will my insurer pay for a generic or biosimilar?
Most policies cover approved versions, but rules differ. Ask your insurer or scheme desk in writing before you change. This is general information, not advice on your policy, so your insurer has the final word.
Is it safe to buy these medicines online?
Only from a licensed pharmacy that asks for a prescription and gives a proper bill. Cancer medicines need correct storage, and fake medicines do circulate. If the price seems far too low, ask your oncologist before using it.
Who should I ask about the right version for me?
Your medical oncologist, who knows your liver function and your plan. Call the CION helpline if you want a second opinion on the medicine or the version, and someone will arrange a consultation.
