Tamoxifen 20 mg is a widely used medication in the treatment and prevention of certain types of breast cancer. As a selective estrogen receptor modulator (SERM), Tamoxifen has proven effectiveness in hormone-receptor-positive breast cancers, significantly improving survival rates and reducing recurrence. Whether you're a patient undergoing treatment or a caregiver seeking accurate information, this article provides comprehensive coverage of everything you need to know about Tamoxifen 20 mg dosage, usage, pricing, and purchasing it from an online pharmacy in France.

What is Tamoxifen 20 mg?

Tamoxifen 20 mg is an oral medication primarily prescribed to treat estrogen receptor-positive (ER+) breast cancer. It works by blocking estrogen receptors in breast tissue, preventing estrogen from binding and fueling the growth of cancer cells. Tamoxifen is also approved for the prevention of breast cancer in high-risk individuals and is commonly used both in pre-menopausal and post-menopausal women.

Brand names such as Tamodex 20 mg tablet are among the commonly used generic versions of this medicine, offering the same therapeutic benefits at a more affordable cost.

Tamoxifen 20 mg Dose: How to Use

The minimum adult dose of tamoxifen is 20 mg. But your dose—based on the severity of the disease, weight, age, and how you respond to therapy—will be customized by your doctor. Below is a general guide:

For Breast Cancer Treatment:

The recommended dosage in the majority of patients is 10 mg once daily.

Duration: Typically five years, but here up to 10 years

For Breast Cancer Prevention:

High-risk individuals (e.g., familial history of breast cancer): 20 mg once per day for up to 5 years

Note: Tamoxifen should be taken at the same time each day - plan a daily drug schedule that will be easy to remember. Don't change your medications for treatment dose without the advice of a health care professional.

Approved Medical Uses in France

In France, Tamoxifène 20 mg is indicated by the ANSM (1) :

Metastatic breast cancer in pre- and post-menopausal women.

Risk reduction therapy in women at high risk of breast cancer (genetic or familial risk) (under specialist supervision).

Drug Interactions

Always tell your doctor about all supplements or medications you take.

Common interactions include:

Specific antidepressants (i.e., fluoxetine, paroxetine, and sertraline) can inhibit the liver enzymes (CYP2D6) involved in activating tamoxifen and may reduce its effectiveness.

Anticoagulants (warfarin)—may increase bleeding risk; adjust dose as needed.

Hormone therapies or contraceptives that contain estrogen can neutralize tamoxifen’s anti-estrogenic effects.

Antifungal or antibiotic medications (ketoconazole, erythromycin) — may change tamoxifen metabolism.

Your healthcare provider may suggest other medicines or change the dose of the medicine you are taking.
