Tykerb Dosage Guidelines: Form, Potency, Administration Method, and Additional Information
Tykerb, the brand name for the oral antineoplastic drug lapatinib ditosylate, is a crucial treatment option for individuals with HER2-positive advanced or metastatic breast cancer. This medication, which belongs to a class of drugs known as tyrosine kinase inhibitors, comes in the form of tablets.
Approved by the Food and Drug Administration (FDA), Tykerb is primarily used in combination therapies to combat HER2-positive breast cancer. It is often prescribed in conjunction with either capecitabine (Xeloda) or letrozole (Femara) for treating metastatic breast cancer that is also hormone receptor-positive (HR+).
The recommended dosage for Tykerb is 1,500 mg once daily, consisting of six 250-mg tablets taken once per day. However, the dosage your doctor prescribes may vary depending on factors such as the type and severity of your breast cancer, other medications you are taking, side effects you experience, your heart function and liver function, and any other medical conditions you may have.
It is essential to follow the dosage prescribed by your doctor and avoid taking more or less than the recommended amount. If you believe you've taken too much Tykerb, call your doctor right away. Additionally, always avoid eating grapefruit or drinking grapefruit juice while taking Tykerb, as it may interact with the medication.
Swallow Tykerb tablets whole and take them 1 hour before or after a meal. If you miss a dose, skip it and take your next dose at your regular time the next day. It is crucial to maintain a consistent dosing schedule to ensure the effectiveness of the treatment.
Currently, there is no generic form of Tykerb available, but it is expected to become available around April 18, 2026, based on estimated patent expiration and generic entry dates controlled by the European Patent Office.
If you take drugs known as CYP3A4 inducers, your doctor may prescribe a higher dosage of Tykerb than usual. Conversely, if you have a heart problem called decreased left ventricular ejection fraction (LVEF) or take certain drugs known as CYP3A4 inhibitors, your doctor may prescribe a lower starting dosage of Tykerb.
