For postmenopausal women who are treating breast cancer with exemestane, dosing typically starts at 25 mg once daily after a meal. Generally, women with early breast cancer can take exemestane after two to three years of taking tamoxifen. Some women who are taking certain other medications may need to take a higher dose of exemestane (50 mg once daily). Do not adjust your exemestane dose unless your healthcare provider specifically instructs you to do so.
Exemestane Dosing: An IntroductionThe dose of exemestane (Aromasin®) that your healthcare provider recommends will vary, depending on a number of factors, including:
- The severity of your breast cancer (see Breast Cancer Stages)
- Other medications you may be taking
- Other medical conditions you may have.
As is always the case, do not adjust your exemestane dose unless your healthcare provider specifically instructs you to do so.
Exemestane Dosing for Breast Cancer
The recommended dose of exemestane in postmenopausal women is exemestane 25 mg once daily after a meal. For women with early breast cancer, exemestane is approved for use after two to three years of tamoxifen (Nolvadex®, Soltamox®) for two to three additional years (for a total of five years of treatment). For women with more advanced breast cancer, exemestane should be continued until the breast cancer worsens.
Women taking certain other medications may need to take a higher dose -- exemestane 50 mg once daily after a meal (see Drug Interactions With Exemestane).
