Can Calquence (acalabrutinib) cause hair loss?
Hair loss is listed as a possible side effect of Calquence (acalabrutinib). Reports include shedding/hair thinning (and, in some cases, scalp hair changes) during treatment. [1]
How common is hair loss with Calquence?
The exact frequency can vary by study and reporting, but hair loss has been captured in Calquence’s safety information as an adverse reaction, which means it can occur in some patients. [1]
What does hair loss look like, and when does it happen?
Hair loss from cancer therapies (including targeted treatments like acalabrutinib) typically shows up as gradual thinning or increased shedding rather than sudden bald patches. Timing can differ from person to person, with some noticing changes after starting therapy and others later during treatment. [1]
Should you stop Calquence if you notice hair loss?
Do not stop Calquence on your own. If you notice hair loss, talk with your prescriber so they can assess whether it’s likely related to Calquence and whether any supportive steps or dose adjustments are needed. [1]
What else can cause hair loss while on Calquence?
Hair loss can also come from other factors that commonly overlap with cancer treatment, such as other medications, illness-related stress, nutritional issues, thyroid problems, or immune-related causes. Your clinician can help sort out the most likely contributor based on your full medication list and health history. [1]
