New cancers, including skin cancer, have happened in people during treatment with BTK (Bruton tyrosine kinase) inhibitors such as CALQUENCE. During clinical trials, skin cancer was reported in 6% of 1029 patients exposed to CALQUENCE.
It’s always important to use sun protection and follow sun safety guidelines when outside in sunlight. Your healthcare provider or dermatologist will check you for skin cancer during treatment with CALQUENCE and can help answer any further questions you may have.
