Sprycel (Dasatinib) — Patient Information (UK)

Sprycel is a prescription medicine containing dasatinib, used to treat certain types of leukaemia. This guide is written to help you understand what the medicine does, how it works, and what to expect in everyday use. It does not replace advice from your healthcare team.

1. Basic product information

If you are not sure which strength you are taking, check your pack and confirm with your pharmacist.

2. How Sprycel works (mechanism of action)

Sprycel contains dasatinib, which belongs to a group of medicines called tyrosine kinase inhibitors (TKIs). Many leukaemias are driven by signals from abnormal proteins. Dasatinib helps block these abnormal signals.

In particular, dasatinib inhibits BCR-ABL tyrosine kinase activity (often found in chronic myeloid leukaemia and certain types of Philadelphia chromosome–positive acute lymphoblastic leukaemia). This can slow or stop cancer cell growth and support remission in eligible patients.

Dasatinib can also affect other kinases involved in cell signalling, which contributes to its anti-cancer activity.

3. Pharmacokinetics (how your body handles it)

Pharmacokinetics describes what the body does to the medicine—how it is absorbed, distributed, metabolised and removed.

• Absorption: Dasatinib is absorbed after oral dosing.
• Time to peak: The medicine reaches its highest levels in the blood after a few hours (exact timing can vary between individuals).
• Protein binding: Dasatinib is significantly bound to blood proteins.
• Metabolism: It is mainly processed by the liver (primarily via CYP enzymes).
• Elimination: The medicine and its metabolites are cleared from the body over time, mainly through the liver and bile pathways.
• Half-life: Dasatinib has a duration in the body that supports once-daily or twice-daily schedules depending on the regimen and indication.

Because dasatinib is metabolised in the liver, liver function and drug interactions can influence how safely and effectively it works for you.

4. What Sprycel is used for (indications)

Sprycel is used to treat specific leukaemias, typically where cancer cells carry the Philadelphia chromosome or related genetic changes involving BCR-ABL. Your specialist will select the indication based on your test results and prior treatment history.

Common indications in clinical use may include:

• Chronic Myeloid Leukaemia (CML)
  • In chronic phase, including in adults who are newly diagnosed or who have had prior treatment.
  • In accelerated phase or blast phase in selected circumstances (where appropriate).
• Philadelphia chromosome–positive Acute Lymphoblastic Leukaemia (Ph+ ALL)
  • In adults or children in certain settings, depending on age group, prior therapy, and eligibility.

Exact availability of indications can depend on local clinical guidelines and the specific UK product licence. Always follow your clinician’s plan.

5. Timing and how to take Sprycel

How often?

Sprycel dosing depends on your individual condition, your treatment phase, and your tolerance. Some regimens use once daily, others twice daily. Use only the schedule your healthcare team provides.

When to take it

• Try to take it at the same time each day to maintain steady medicine levels.
• If you are taking it twice daily, spread doses roughly 12 hours apart unless your prescriber advises otherwise.
• If you miss a dose, do not double up to make up for it—ask your pharmacist for guidance.

How to swallow the tablets

• Swallow the tablets whole with water.
• Do not crush, split, or chew unless your pharmacist or clinician instructs you otherwise.

Practical routine tips

• Consider a pill organiser for daily doses (only if advised safe with your tablet formulation).
• Keep a medication diary to track doses and side effects.
• If you have mobility or memory challenges, set phone alarms or use a dosing chart.

6. Food interactions and eating while taking Sprycel

Food can affect how much of a medicine gets absorbed. For dasatinib, the impact of food may be clinically relevant. In many cases, guidance recommends taking dasatinib consistently with respect to meals.

General patient-friendly advice:

• Follow the directions on your medicine label or the instructions from your clinic.
• If you are told to take it with or without food, keep to that approach each time.
• Avoid making frequent changes (for example, switching between “with meals” and “on an empty stomach”) without asking your pharmacist.

If you have dietary concerns (e.g., nausea affecting meals), speak with your healthcare team so they can help you manage symptoms while keeping dosing consistent.

7. Alcohol interactions

Alcohol does not typically have a single “direct” interaction that everyone will experience with dasatinib, but it may increase the risk of side effects—particularly those involving the liver, tiredness, dizziness, or stomach upset.

• Prefer to limit alcohol while you are taking Sprycel.
• If you have liver problems, ask your clinician for specific advice.
• Be cautious if you experience fatigue, light-headedness, or nausea—alcohol can worsen these for some people.

If you would like, tell your pharmacist how much alcohol you usually drink so they can advise safely.

8. Interactions with other medicines (including common medicines)

Dasatinib can interact with other medicines due to liver metabolism and changes in stomach acidity. Some interactions can be significant.

Stomach acid–reducing medicines (important)

Medicines that change stomach acidity can affect dasatinib absorption. This includes:

• Proton pump inhibitors (PPIs) (e.g., omeprazole, esomeprazole, lansoprazole)
• H₂-receptor antagonists (e.g., famotidine)
• Antacids (e.g., aluminium/magnesium preparations)

Your healthcare team may recommend alternatives or timing adjustments. Do not start or stop acid-suppressing medicines without checking first.

Enzyme-inducing medicines (can reduce effect)

Some medicines can increase liver enzyme activity, potentially reducing dasatinib blood levels. Examples include certain anticonvulsants and some treatments used for infections. Always share your full list of medicines with your pharmacist.

Other anticancer and blood-related medicines

• Other medicines that also affect blood counts can increase the risk of low blood cells (e.g., anaemia, infection risk, bleeding risk).
• Combination therapy can require close monitoring.

Herbal and over-the-counter products

• Be cautious with St John’s wort and other herbal products.
• Always check OTC cold/flu remedies, supplements, and pain relief options for compatibility.

What to do

• Keep an up-to-date list of all medicines, including creams, inhalers, eye drops, and supplements.
• Ask your pharmacist to check interactions, especially before starting new medicines.
• Do not stop Sprycel if another medicine is proposed—ask first about safe alternatives.

9. Dosing (overview and adjustments)

Your dose of Sprycel depends on your indication and clinical factors. Dosage may be modified during treatment based on blood test results, side effects, and overall tolerance.

Typical dosing patterns (general)

• Adults: Doses vary by the phase of disease and treatment history; many regimens use once-daily or twice-daily dosing.
• Children/young people: Dosing is typically weight- or protocol-based and may differ from adult schedules.

The exact dose strength and schedule must follow your individual plan.

Dose adjustments

If side effects occur—especially severe blood count changes or significant non-haematological toxicities— your clinician may:

• Interrupt treatment temporarily
• Reduce the dose
• Stop treatment if risks outweigh benefits

Do not adjust your dose yourself. Always contact your treating team for advice.

10. Safety profile (what to watch for)

Like all medicines, Sprycel can cause side effects. Not everyone will experience them, and many can be managed with monitoring, dose adjustment, and supportive treatment.

Commonly monitored issues

• Blood cell changes: low white blood cells and/or platelets may increase infection or bleeding risk.
• Infections: because of changes to the immune system.
• Fatigue and reduced energy levels.
• Gastrointestinal effects: nausea, diarrhoea, abdominal discomfort.
• Muscle or joint discomfort in some patients.
• Headache.

Serious side effects (seek medical help urgently)

Contact urgent medical services or your oncology team right away if you develop:

• Breathing difficulties, chest pain, or sudden shortness of breath
• Fever or signs of infection (especially if you feel unwell and have low blood counts)
• Unusual bruising, bleeding, black stools, or blood in urine/vomit
• Severe or persistent vomiting or inability to keep fluids down
• Severe rash, swelling of the face/lips, or signs of allergy
• Severe dizziness or fainting

Monitoring while on Sprycel

Your healthcare team will likely monitor:

• Full blood counts regularly
• Liver function blood tests
• Symptoms related to fluid retention and breathing
• Heart-related symptoms if risk factors exist (your clinician will advise)

If you receive blood test schedules or symptom checklists, keep them and attend appointments as planned.

11. Practical use tips (day-to-day guidance)

• Take a consistent dose: use the same timing each day.
• Keep follow-up appointments: monitoring is central to safe treatment.
• Know your “red flags”: fever, shortness of breath, bleeding, or severe weakness should be reported promptly.
• Stay hydrated: especially if you have diarrhoea or reduced appetite.
• Protect yourself from infection: practice good hand hygiene and follow advice about vaccination timing.
• Manage nausea early: if nausea happens, ask about anti-nausea options rather than waiting until it worsens.
• Track symptoms: jot down new symptoms, when they started, and what makes them better/worse.

12. Alternative options (what your clinician may consider)

In leukaemia, treatment choice depends on disease subtype, genetic features, prior therapies, age, and overall health. If Sprycel is not suitable due to side effects, resistance, or other factors, your specialist may discuss alternatives.

Possible alternative approaches can include:

• Other BCR-ABL tyrosine kinase inhibitors (TKIs), depending on availability and indication.
• Chemotherapy in certain settings, sometimes combined with targeted therapy.
• Immunotherapy or cellular treatments where appropriate and in specific clinical pathways.
• Supportive and symptom-relieving care to manage side effects (for example, infection prevention strategies and blood support).

Discuss options with your oncology team; switching therapies should be carefully planned with monitoring.
