- Adjuvant Treatment: For most patients, the standard dose is 20 mg taken orally once a day.
- Metastatic Breast Cancer: The initial dose may start at 20 mg, which can be increased to 40 mg depending on response and tolerability.
- Preventive Use: Women at high risk of breast cancer often take 20 mg daily for five years.

Consulting with Healthcare Providers
It’s crucial to have regular discussions with healthcare providers about tamoxifen dosage. Adjustments may be necessary over time based on how well the patient responds to treatment and their ability to tolerate any side effects.
