Sorafenib (Nexavar, Soranib): — A Guide for Patients and Families

Both contain the same active medicine, sorafenib, and work in exactly the same way. Nexavar is the original brand made by Bayer; Soranib is a licensed generic manufactured by Cipla in India. The main practical difference is cost — Soranib is considerably less expensive, which matters when treatment continues for months or longer. Your oncologist will advise which is appropriate, and your insurance or government scheme may cover one but not the other. Ask at your first dispensing appointment so you are not caught off guard.

Hand-foot skin reaction — redness, tenderness, numbness or peeling on the palms and soles — is the side effect most closely associated with sorafenib. It can become severe enough to affect walking or using your hands if it is not caught early. Tell your team as soon as you notice any change to the skin on your hands or feet, even if it seems mild. Keeping the skin well moisturised, wearing soft footwear and avoiding unnecessary pressure on affected areas are the first steps. Your team can adjust your dose or prescribe a specific cream if it becomes troublesome.

Yes, and this matters more than it might seem. Sorafenib interacts with a number of medicines, including some commonly prescribed for blood pressure and heart conditions. Grapefruit and Seville oranges are known to affect how certain drugs are processed by the body. Herbal and Ayurvedic preparations are generally not tested alongside cancer medicines, and some plant-based preparations affect the liver's ability to process sorafenib — which can change how much of the drug reaches your bloodstream. Tell your oncologist and pharmacist about every medicine, supplement or preparation you take, including things bought without a prescription. They need to know, and there is no judgement in asking.

Your oncologist will use imaging — usually a CT or MRI scan — at regular intervals to assess the disease. For liver cancer, certain blood markers may also be monitored. The goal of sorafenib is often to stabilise the disease rather than shrink it, so a scan showing the tumour has not grown is a meaningful, positive result — not a disappointing one. How you feel day to day is not a reliable guide to response: the treatment can be working without you feeling noticeably better, and tumours can progress with few symptoms. Trust the imaging results and your oncologist's interpretation of them.

Some thinning or change in hair texture is possible with sorafenib, but the significant hair loss associated with conventional chemotherapy — where large amounts fall out in a short time — is not typical with this drug. Any change tends to be gradual and partial. Hair texture may also change while you are on treatment. Tell your team if the change feels more than mild, as it can occasionally point to other issues worth checking. Most people find any hair change on sorafenib manageable compared to what they had expected.

Yes. Sorafenib is prescribed and monitored at CION centres. Because it is a tablet taken at home rather than an infusion, you will not come in for each dose — but regular monitoring appointments are built into your treatment plan from the start. Your team will track your blood pressure, blood counts and liver function, and coordinate response-assessment scans including PET-CT through partner imaging centres where needed. If a side effect concerns you between appointments, contact the team that day rather than waiting for your next scheduled visit.
