Tasigna (Nilotinib) — Patient Information (United Kingdom)

Tasigna is a prescription medicine used to treat certain blood cancers, including chronic myeloid leukaemia (CML) with specific genetic changes. This guide is written in clear, patient-friendly language to help you understand how Tasigna works, how it is usually taken, and what to consider for day-to-day use in the UK.

Always follow the instructions given by your healthcare team. Information below is general and may not cover every personal situation.

1) Basic product information

2) What Tasigna is used for (indications)

Tasigna is used to treat Philadelphia chromosome–positive (Ph+) chronic myeloid leukaemia (CML), in adults, including:

• Newly diagnosed Ph+ chronic-phase CML
• Chronic-phase CML when the disease is resistant or after failure of prior therapy

Your specialist will decide whether Tasigna is appropriate based on your blood counts, genetic test results, treatment history, and monitoring results.

3) Mechanism of action (how it works)

CML is driven by an abnormal protein called BCR-ABL, which signals cells to grow and multiply uncontrollably. In Ph+ CML, the BCR-ABL fusion gene produces a tyrosine kinase that drives the disease.

Nilotinib blocks (inhibits) the BCR-ABL tyrosine kinase. By reducing this signalling, Tasigna helps:

• Control leukaemia cell growth
• Allow blood counts to return toward normal
• Reduce the number of cancer cells over time
• Support long-term disease control for appropriate patients

4) Pharmacokinetics (what the body does to Tasigna)

“Pharmacokinetics” describes how the medicine is absorbed, distributed, broken down, and eliminated. Key points for Tasigna include:

• Absorption: Nilotinib is absorbed after swallowing the capsules. A key safety/efficacy factor is that food—especially certain meals—can significantly increase drug exposure.
• Distribution: Once absorbed, nilotinib travels in the bloodstream and reaches tissues where it can act on target cells.
• Metabolism: Nilotinib is mainly metabolised in the liver, involving enzymes such as CYP3A4.
• Elimination: The medicine and its metabolites are eliminated mainly via the bile/feces pathway.
• Half-life: It has a dosing interval designed to maintain effective exposure while managing safety considerations.

Practical implication: Because nilotinib exposure can vary with food and with interactions affecting CYP3A4, your exact dosing schedule and avoidance of interacting substances are important.

5) Typical dosing schedule and timing

Tasigna dosing depends on your diagnosis (newly diagnosed vs. resistant/refractory), disease phase, and how you respond. Your prescriber will specify the exact dose for you. Common adult regimens are:

• Newly diagnosed Ph+ chronic-phase CML: often 300 mg twice daily
• Other Ph+ chronic-phase CML (resistance/intolerance to prior therapy): often 400 mg twice daily

Important: Dose changes may be made based on blood test results, side effects, heart monitoring, and treatment response milestones. Do not adjust your dose unless your specialist tells you to.

How to take Tasigna

• Swallow capsules whole with water.
• Do not take with food.
• Avoid eating close to your dose (see food section below).
• Try to take doses at roughly the same times each day.

Timing around meals (food interaction guidance)

Food can increase nilotinib absorption, which may raise the risk of side effects. A commonly used rule in clinical practice is:

• Take Tasigna at least 2 hours after food and wait at least 1 hour before eating after the dose.
• Follow the schedule you were given by your oncology team/pharmacist, especially if they provided a stricter plan.

If you miss a dose, follow the instructions from your healthcare team. Do not take double the next dose to make up for a missed one.

6) Food interactions (what to avoid)

The most important food interaction is that Tasigna should be taken on an empty stomach. This is because a meal can substantially increase drug levels.

Practical tips:

• Choose regular meal times so you can plan your capsules around them.
• If you prefer breakfast, consider taking your morning dose after breakfast rather than with it—while keeping the timing rules.
• Avoid changing your diet drastically without telling your clinician, especially if you have weight loss or reduced appetite.

7) Alcohol and medicine interactions

Alcohol

There is no universal rule that all patients must avoid alcohol completely. However, alcohol may:

• Increase strain on the liver (important because nilotinib is metabolised in the liver)
• Worsen nausea or fatigue
• Increase the likelihood of missed doses due to timing problems

If you drink alcohol, consider discussing a personalised approach with your healthcare team—particularly if you have liver issues or abnormal liver function tests.

Medicine interactions (especially CYP3A4-related)

Nilotinib levels can be affected by other medicines that influence CYP3A4. This can lead to:

• Increased nilotinib exposure (higher risk of side effects)
• Reduced nilotinib exposure (possible loss of effectiveness)

Tell your specialist/pharmacist about all medicines and supplements you take, including:

• Medicines for infections (e.g., some antibiotics and antivirals)
• Medicines for heart rhythm or blood pressure
• Medicines for acid reflux (some can affect absorption)
• Anti-fungal medicines
• Herbal products (particularly St John’s wort)
• Over-the-counter products you buy without prescription

General caution: Avoid starting new medicines (including short courses) without checking interactions. Your pharmacist can quickly screen most interactions.

Note: Tasigna also has cardiac safety considerations (see safety section). Medicines that affect heart rhythm or potassium/magnesium levels may be of particular concern.

8) Safety profile and important warnings

Like all medicines, Tasigna can cause side effects. Many are manageable with monitoring and supportive care, but some require prompt medical attention.

Common side effects

• Fatigue
• Nausea
• Headache
• Skin rash
• Diarrhoea or constipation
• Muscle or joint pain
• Low blood counts (anaemia, neutropenia, thrombocytopenia) — often monitored through regular blood tests

Serious or important risks (monitor closely)

Your healthcare team will monitor you closely, often with blood tests and heart assessments. Seek medical advice urgently if you experience symptoms consistent with the conditions below.

• Heart rhythm changes (QT prolongation): Tasigna may affect the heart’s electrical system. Your clinician may perform ECGs and check electrolytes. Symptoms to take seriously include palpitations, dizziness, fainting, or severe light-headedness.
• Cardiovascular effects: There is an increased risk of certain cardiovascular events in some patients. Your doctor may assess risk factors such as previous heart disease, blood pressure, cholesterol, smoking status, and diabetes.
• Metabolic effects: Nilotinib can influence blood sugar and cholesterol in some people.
• Liver effects: Changes in liver enzymes may occur, so liver function tests are monitored.
• Pancreatic effects (rare): Tell your clinician if you develop severe abdominal pain, especially with vomiting.

Who may need extra caution?

• People with a history of QT prolongation or significant heart disease
• People taking other medications that may also affect heart rhythm
• People with low potassium or magnesium levels
• People with liver impairment or raised liver enzymes

When to contact your healthcare team urgently

Contact urgent care/your clinical team if you develop:

• Fainting, severe dizziness, or sudden palpitations
• Chest pain or symptoms suggestive of stroke
• Severe or persistent abdominal pain, especially with fever or vomiting
• Signs of infection (fever, chills) if your blood counts are low

9) Practical use tips (helpful day-to-day guidance)

• Set reminders: Tasigna is usually taken twice daily. Consistent timing helps maintain steady exposure.
• Keep an “empty stomach” routine: Plan meals and snacks around your doses to avoid food-related absorption changes.
• Hydration: Drink water with your capsules. If you experience diarrhoea, maintain fluid intake.
• Blood tests and monitoring: Attend all appointments for ECGs, blood counts, liver tests, lipids, and electrolytes as scheduled.
• Medication list: Keep an up-to-date list (including OTC products and supplements) to review at each appointment.
• Report new symptoms promptly: Early reporting improves the ability to manage side effects.
• Storage: Store capsules according to the package instructions (commonly at room temperature, away from moisture and heat).

10) How to handle missed doses

If you miss a dose, follow the advice provided by your healthcare team or the medicine leaflet. In general, patients should avoid taking extra capsules to “catch up” unless instructed.

If you are unsure, contact your pharmacist for guidance. Having a missed-dose plan can reduce stress during treatment.

11) Alternative options to consider

Treatment choice for CML depends on treatment phase, prior therapy, response goals, and safety considerations. Other medicines in the same therapeutic area (tyrosine kinase inhibitors) may be considered by your specialist, such as:

• Imatinib
• Dasatinib
• Bosutinib
• Ponatinib (for selected cases)

If Tasigna is not suitable due to side effects or interactions, your clinician may recommend switching to another option. Do not switch without specialist guidance, because dosing schedules and food restrictions can differ.
