Calquence (Generic Acalabrutinib)
Actual product appearance may differ slightly.
Why is this medication prescribed?
Mantle cell lymphoma (MCL), a quickly progressing malignancy that starts in immune system cells, is treated with acalabrutinib after at least one prior chemotherapeutic drug has failed to control the disease. It is also used to treat small lymphocytic lymphoma and chronic lymphocytic leukaemia (CLL, a kind of malignancy that starts in the white blood cells), either alone or in combination with obinutuzumab (Gazyva) (SLL: a type of cancer that begins in the white blood cells). Kinase inhibitors are a class of drugs that includes acalabrutinib. It functions by preventing the aberrant protein from signalling cancer cells to proliferate. The spread of cancer cells is halted as a result.
How should this medicine be used?
Acalabrutinib is available as a pill to swallow. It is typically taken every 12 hours (twice a day), with or without food, for however long your doctor suggests you receive treatment. Acalabrutinib should be taken every day at roughly the same time. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Provide acalabrutinib exactly as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.
With a glass of water, swallow the capsules whole; do not open, chew, or break them.
Depending on the negative effects you experience, your doctor may shorten or discontinue your acalabrutinib medication altogether. Make careful to discuss your feelings during treatment with your doctor. Without consulting your doctor, do not discontinue taking acalabrutinib.

What should I know about storage and disposal of this medication?
Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).
Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at http://goo.gl/c4Rm4p for additional information.
