Sorafenib (Nexavar)
Tests and Monitoring — While You Are on Sorafenib
Sorafenib works across multiple pathways in the body, which means it can affect blood pressure, liver function, and other systems alongside the cancer. Regular tests are how your team catches those changes early, before they become uncomfortable or unsafe.

- Starts before your first tablet — Baseline blood tests are done before treatment begins so your team has a reference point for every result that follows.
- Blood pressure is the most frequent check — Sorafenib commonly raises blood pressure. Home monitoring between visits may be part of your plan.
- Liver and blood count are checked regularly — Liver enzymes and blood cell levels are monitored throughout treatment, typically every few weeks at the start.
- Skin reactions are watched at every visit — Hand-foot skin reaction does not show up in a blood test. Your team will look at your palms and soles at each appointment.

When you are on sorafenib, regular blood tests and blood pressure checks are part of the treatment. They detect side effects early, when they are easier to manage. Blood pressure, liver function, and blood count are monitored most often. Tell your team about any new symptom between visits — do not wait.
How monitoring is set up from the start
Before your first dose
Your team runs baseline blood tests covering liver function, kidney function, blood count, thyroid, and electrolytes. These results become the reference point for everything that follows. Your blood pressure is recorded at this visit too.
First two to four weeks
Blood tests and blood pressure are checked more frequently at the start of treatment. This is when the body is adjusting to sorafenib and when side effects are most likely to appear for the first time.
Each follow-up visit
As your results stabilise, monitoring typically moves to every four to six weeks. Blood pressure, liver function, blood count, and kidney function are checked at most visits. Your team will also examine your hands and feet.
Between visits
You may be asked to check your blood pressure at home and keep a log. If anything changes — a new rash, unusual fatigue, yellowing of the skin or eyes — call your team the same day rather than waiting for your next appointment.
When a result is abnormal
Depending on what is found, your team may ask you to return sooner, adjust your dose, or pause treatment while the result is investigated. Most dose adjustments are temporary. An abnormal result is information that lets your team act — not a sign the treatment is failing.
What to bring to every appointment
- Your home blood pressure log, if your team asked you to keep one
- A list of any new symptoms since your last visit, even ones that seem minor
- All medicines, supplements, and herbal preparations you are currently taking
- Any new prescription from another doctor or dentist
- Your sorafenib tablets, so your team can confirm the dose and timing

What each test is looking for — and when to act
| Test | What it checks for | When your team needs to know |
|---|---|---|
| Blood pressure | Sorafenib commonly raises blood pressure, sometimes significantly, even in people whose blood pressure was normal before starting treatment | Any reading notably higher than your usual, or any headache, visual disturbance, or chest discomfort — call the same day |
| Liver function (ALT, AST, bilirubin) | Sorafenib can affect liver enzyme levels; this is monitored especially carefully in patients being treated for liver cancer | Yellowing of the skin or eyes, dark urine, right-sided abdominal pain, or results that are rising visit on visit |
| Blood count (CBC) | Platelet and white cell levels, which sorafenib can reduce in some patients | Unusual bruising, bleeding that is hard to stop, signs of infection, or marked unexplained fatigue |
| Kidney function (creatinine, electrolytes) | Sorafenib can alter the kidney's handling of certain electrolytes, including phosphate and calcium | Significant swelling in the legs, a noticeable change in urine output, or results trending away from your baseline |
| Thyroid function (TSH) | Sorafenib can cause an underactive thyroid in some patients, particularly those being treated for thyroid cancer | Unexplained weight gain, persistent fatigue, or feeling cold in a way that is new for you |
| Typically starts | Baseline tests are taken before your first tablet; monitoring continues at each visit for the full duration of treatment | Any new symptom between visits — do not wait for your next scheduled appointment |
Why your hands and feet need a check at every visit
Hand-foot skin reaction does not show up in a blood test, but it is one of the most common side effects of sorafenib. It causes redness, tenderness, blistering, or thickening of skin on the palms and soles.
NCCN guidelines on sorafenib include examination of the hands and feet at every clinic visit as part of routine monitoring. If you notice these changes between visits, contact your team before they worsen — early treatment, including prescription creams and dose adjustment, works much better than waiting.
Do not walk barefoot on hard floors and avoid tight shoes. Keeping skin well-moisturised from the first week of treatment, before any reaction develops, reduces its severity in a proportion of patients.

Common questions
Frequently asked questions
How often will I need blood tests on sorafenib?
Most often every four to six weeks once your results are stable, and more frequently in the first weeks of treatment when the body is adjusting. Your team will set the schedule based on your baseline results, your cancer type, and how your body responds. The frequency can increase again if a result needs to be watched more closely, or ease off if everything remains stable over a longer period.
Can I skip a monitoring appointment if I feel well?
No. Feeling well does not mean the monitored values are normal. The changes sorafenib causes in the liver or blood pressure often produce no symptoms until they become significant. These appointments are not a check on how you feel — they are a check on what is happening that you cannot feel. Skipping them removes your team's ability to catch problems early, when they are easiest to manage.
Should I check my blood pressure at home between appointments?
Ask your team — many oncologists will recommend it, particularly if your blood pressure has risen since starting sorafenib. A basic automatic cuff from a pharmacy is sufficient. If your team asks you to keep a log, bring it to every visit. If you ever get a reading that is markedly higher than your usual, or you develop a headache with visual changes, call the same day rather than waiting for your next appointment.
What happens if one of my blood tests comes back abnormal?
It depends on which test and how far from your baseline it has moved. For a mildly elevated result, your team may repeat the test sooner and continue treatment with close observation. A more significant result may lead to a dose reduction or a temporary pause while the value is investigated and settles. Stopping sorafenib permanently is a last resort. Most abnormal results are managed without ending treatment, and acting early is what keeps the milder options available.
Are there tests I should have before starting sorafenib?
Yes. Baseline blood tests are done before your first dose so that every result during treatment has a reference point. These typically cover liver function, kidney function, blood count, thyroid, and electrolytes, and your blood pressure is recorded. If the baseline tests show anything that needs attention first, your oncologist will address that before starting. The pre-treatment checks are a standard part of beginning sorafenib — not a sign that something is already wrong.
