Summary

  • Tucatinib is used to treat HER2-positive breast cancer, which is a type of cancer that tests positive for a protein called human epidermal growth factor receptor 2. This protein promotes the growth of cancer cells. Tucatinib is often used in combination with other therapies to enhance its effectiveness.

  • Tucatinib works by blocking a protein called HER2, which is found in some cancer cells. This protein helps cancer cells grow and spread. By blocking HER2, Tucatinib slows or stops the growth of these cancer cells, helping to control the disease and improve outcomes for patients.

  • The usual starting dose of Tucatinib for adults is 300 mg taken twice daily. It is taken orally, which means by mouth, with or without food. Always follow your doctor's specific dosing instructions for your personal health needs.

  • Common side effects of Tucatinib include diarrhea, nausea, and fatigue, which means feeling very tired. These effects vary from person to person and are usually mild to moderate. If you experience severe or persistent symptoms, consult your healthcare provider.

  • Tucatinib can cause liver problems, so regular liver function tests are recommended. If you experience symptoms like yellowing of the skin or eyes, contact your doctor immediately. Tucatinib is not recommended during pregnancy or breastfeeding due to potential risks to the baby.
