Cancer drugs A to Z list
Nilotinib is a type of targeted cancer drug. It is also known as Tasigna. It is a treatment for chronic myeloid leukaemia (CML).
You might have nilotinib:
as a first treatment for chronic phase CML if you can’t have imatinib
if other treatment such as imatinib doesn't work, stops working or is causing difficult side effects
Treatment for chronic myeloid leukaemia (CML)
Nilotinib is a type of targeted cancer drug called a tyrosine kinase inhibitor (TKI). Tyrosine kinases are proteins that act as chemical messengers and can stimulate cancer cells to grow.
Nilotinib blocks a tyrosine kinase protein called BCR-ABL. The protein is made by CML cells that have an abnormal chromosome called the . Blocking this protein stops the leukaemia cells that have the Philadelphia chromosome growing. Most people with CML have the Philadelphia chromosome.

You take nilotinib as capsules.
You swallow the capsules whole with water. You take nilotinib on an empty stomach. This means taking your capsules at least 2 hours before a meal and you not eating for 1 hour after.
If you can't swallow the capsules, you can mix the powder from the capsule with a teaspoon of apple sauce. You need to swallow it immediately and don't use any food other than apple sauce.
Whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, not more or less.
Talk to your healthcare team before you stop taking a cancer drug, or if you have missed a dose.
You take nilotinib twice a day about 12 hours apart.
You take nilotinib for as long as it is working and you are not experiencing too many side effects.
Your doctor may stop nilotinib if your CML has been very well controlled for a number of years.
You have blood tests before and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
Before treatment starts you may have a blood test to check for viruses such as hepatitis B, hepatitis C, and . This is called a viral screen.
It’s important for your doctor to know if you have had any of these viruses. This is because this treatment can weaken your and can cause the virus to become active again (reactivation).
You also have an before you start this treatment, and regularly while you have treatment.

Side effects can vary from person to person. They also depend on what other treatments you're having.
Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:
you have severe side effects
your side effects aren’t getting any better
your side effects are getting worse
Early treatment can help manage side effects better.
We haven't listed all the side effects here. Talk to your healthcare team if you have any new symptoms that you think might be a side effect of your treatment.
Remember it is very unlikely that you will have all of these side effects. But you might have some of them at the same time.
These side effects happen in more than 10 in 100 people (more than 10%). You might have one or more of them. They include:
Skin problems include a skin rash and itching. Less commonly nilotinib can make your skin dry, red, cracked, sore, and spotty.
Rarely your skin can have areas that feel thinner or thicker. You might develop cysts, lumps and have patchy areas where your skin is lighter or darker in colour. Your skin might also be more sensitive to light.
Let your doctor, nurse or pharmacist know of any skin changes. They can let you know what you can use to help.
The upper part of your breathing system includes the mouth, nose, nose passages, throat and voice box.
There is a chance you can get an infection whilst on nilotinib to this part of the body. Symptoms can include a sore throat, runny or stuffy nose, sneezing, cough, high temperature, lack in energy and generally feeling unwell.
Let your healthcare team know if you have any of these symptoms
Nilotinib can cause headaches. It can also cause a severe headache, often called a migraine, but this happens less often.
Tell your doctor or nurse so they can give you painkillers to help.
Nilotinib can cause liver changes. These are usually picked up on blood tests and are mild and unlikely to cause symptoms.
Rarely your liver might get bigger or stop working properly. This can cause symptoms such as yellowing of the skin and whites of the eyes, passing dark coloured urine or you might feel sick.
You have regular blood tests to check for any changes in the way your liver is working. Let your healthcare team know if you have any of these symptoms.
Nilotinib commonly causes pain in your muscles, joints, back and tummy (abdomen). It can also cause pain in other areas of the body such as your mouth, throat, chest and bones but this is less common.
Rarely your breasts can hurt. Your body may also feel stiff and you might have joint swelling.
Let your doctor or nurse know if you are in any pain so that they can give you painkillers.
Tiredness and weakness (fatigue) can happen during and after treatment. Doing gentle exercises each day can keep your energy up. Don't push yourself, rest when you start to feel tired and ask others for help.
Feeling or being sick is usually well controlled with anti sickness medicines. It might help to avoid fatty or fried foods, eat small meals and snacks and take regular sips of water. Relaxation techniques might also help.
It is important to take anti sickness medicines as prescribed even if you don’t feel sick. It is easier to prevent sickness rather than treat it once it has started.

Contact your advice line if you have diarrhoea. For example, in one day you have 2 or more loose bowel movements than usual. If you have a , you might have more output than normal. Your doctor may give you anti diarrhoea medicine to take home with you after treatment.
Try to eat small meals and snacks regularly. It’s best to try to have a healthy balanced diet if you can. You don’t necessarily need to stop eating foods that contain fibre. But if your diet is normally very high in fibre, it might help to cut back on high fibre foods such as beans, nuts, seeds, dried fruit, bran and raw vegetables.
