Entax 20 mg Tablet

Entax 20 mg Tablet is a prescription anti-cancer medicine that contains tamoxifen 20 mg in each tablet. Tamoxifen is a selective estrogen receptor modulator (SERM) used in hormone receptor-positive breast cancer treatment and risk reduction. Entax 20 mg Tablet may be used as part of treatment after surgery, with other cancer therapy, or for certain people who need ongoing hormone-related breast cancer care. It is manufactured by Neon Laboratories and supplied as a strip/box of 10 tablets.

How it works: Tamoxifen in Entax 20 mg Tablet blocks estrogen from attaching to hormone receptors in breast tissue, which can slow or stop the growth of estrogen-sensitive cancer cells. As a tablet, it is taken by mouth and absorbed into the body to provide ongoing anti-estrogen effect over time.

Entax 20 mg Tablet is the higher-strength sibling of Entax 10 mg Tablet, so it is usually chosen when a doctor wants the full 20 mg daily dose or a specific treatment plan that calls for fewer tablets per day. Because this is a 20 mg strength, it is not a starter dose for everyone; your doctor will decide whether this tablet strength fits your stage of treatment, tolerance, and overall plan.

• Hormone receptor-positive breast cancer
• Adjuvant treatment after breast cancer surgery
• Reduction of breast cancer recurrence risk
• Breast cancer treatment in selected patients
• Doctor-directed endocrine therapy

• Swallow the Entax 20 mg Tablet whole with water; do not crush or chew unless your doctor tells you to.
• Take it at the same time each day to help you remember your dose.
• You can take Entax 20 mg Tablet with or without food.
• If your stomach feels upset, taking it with a meal may help.
• Do not take extra tablets to make up for a missed dose unless your prescriber instructs you to.
• Follow your oncologist’s schedule exactly, since the tablet strength is 20 mg and the total daily amount matters.

Each Entax 20 mg Tablet provides tamoxifen 20 mg. Depending on the reason it is prescribed, a doctor may tell you to take it once daily or on another schedule that matches your treatment plan; the exact dose and duration are individualized. Do not exceed the amount your doctor prescribed, because the correct daily total depends on your cancer history, other medicines, and risk factors.

Do not change your dose or stop the medicine without speaking to your doctor.
