Calquence (acalabrutinib) is a targeted cancer treatment used for chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), and mantle cell lymphoma (MCL), in certain patients. It helps slow the progression of cancer and helps extend patients’ lives. Calquence works by blocking a protein called Bruton tyrosine kinase (BTK), which plays a key role in cancer cell growth and division. By inhibiting BTK, Calquence helps to slow cancer growth.
Benefits
- Offers a targeted treatment for CLL, SLL, and MCL by selectively inhibiting BTK.
- Demonstrated high response rates and durable remissions in clinical studies.
- Can be used as first-line therapy or in relapsed/refractory settings.
- Lower risk of some side effects compared to earlier BTK inhibitors (e.g., ibrutinib).
- Convenient oral capsules, taken at home, improving quality of life and treatment adherence.
- May delay or eliminate the need for chemotherapy in some patients.
Dosage
- Standard dose: 100 mg orally every 12 hours (total of 200 mg/day).
- Capsules should be swallowed whole with water, with or without food.
- Continue treatment until disease progression or unacceptable toxicity.
- Dose adjustments may be required in the case of side effects or drug interactions.
Warnings and Precautions
- Serious infections (bacterial, viral, or fungal) may occur; monitor for fever, cough, or other infection signs.
- Risk of bleeding, including severe and fatal cases; caution in patients on blood thinners or with bleeding disorders.
- May cause atrial fibrillation or other heart rhythm abnormalities; patients with cardiovascular risk factors should be monitored.
- Can lead to cytopenias (low blood cell counts); regular blood tests are necessary.
- Second primary cancers, including skin cancers, have been reported; sun protection is recommended.
- Use with caution in patients with liver impairment.
- Avoid use during pregnancy or breastfeeding. Effective contraception is required during and for 1 week after the last dose.
- Avoid strong CYP3A inhibitors or inducers, which can alter acalabrutinib levels significantly.
Usage Instructions
- Take one capsule (100 mg) every 12 hours, consistently at the same times each day.
- Swallow capsules whole; do not open, crush, or chew.
- If a dose is missed, take it as soon as possible unless it’s within 3 hours of the next dose—then skip the missed dose.
- Regular monitoring (blood tests, ECGs, checkups) is essential during treatment.
- Do not stop treatment unless directed by your doctor.
Common Side Effects
Mild to moderate effects: headache, diarrhea, constipation, fatigue, muscle or joint pain, cough, nausea, easy bruising.
Serious (seek medical attention): signs of infection (such as fever, chills, or sore throat), irregular heartbeat or chest discomfort, unusual bleeding or bruising, swelling or difficulty breathing, sudden weight gain, severe headaches, or changes in vision or mental status, and any new or changing skin lesions that could indicate skin cancer.

Will the pills or packaging be different when I order from YouDrugstore?
If you usually take a brand name pill and have instead ordered a generic drug, your pills may look different. Although they may look different, generic versions of a drug have the same active ingredients and work in exactly the same way as the brand-name medication. The appearance of medication or packaging may also differ from country to country, even though the strength is the same. For example, Celexa 20MG is usually a peach-colored pill, but in Canada it is white and slightly smaller, even though the same company manufactures both pills. Two different brands of generic medication may also look different because they are made by different manufacturers, although they are equivalent in every other way.
How does medication from Canada differ from medication in other regions of the world?
Canada has high standards and regulations governing the manufacturing of medication and health products and the licensing of doctors and pharmacists. Despite some possible cosmetic differences, medication from Canada is the same quality and strength as medication from other areas like the United States.
Why are prices on YouDrugstore different from prices at other pharmacies?
Unlike some regions of the world, Canadian medication prices are regulated with limits on how much patients have to pay for their prescriptions. This means that Canadian drug costs are often lower than other regions.
