TUKYSA Will be Sent to You by a Specialty Pharmacy

A Specialty Pharmacy understands the unique needs of people living with cancer. Specialty Pharmacies also fill prescriptions for medications that may not be available at your local pharmacy.

In most cases, your TUKYSA (tucatinib) prescriptions will be filled in 1 of the following ways:

  • Your healthcare provider may send your prescriptions to a Specialty Pharmacy; or
  • There may be a pharmacy at your healthcare provider's office or hospital that can fill your prescriptions for pick-up or delivery to your home

Your TUKYSA and capecitabine may come from two different pharmacies. If you have any challenges in coordination of care or scheduling deliveries, Seagen has dedicated staff, Seagen Secure, to help support you in obtaining your medicines.
