Tamoxifen 20 mg (Tamoxifen Citrate) – 30 Tablets

Tamoxifen 20 mg is a prescription medication containing the active ingredient Tamoxifen Citrate. It is a highly important drug used in oncology for the treatment and prevention of hormone receptor-positive (HR+) breast cancer. This 30-tablet package is manufactured by Deva.

In addition to its primary medical use, Tamoxifen is also one of the most common “off-label” compounds used by men as a Post-Cycle Therapy (PCT) agent after an anabolic steroid cycle.

Product Overview: Tamoxifen 20 mg (Tamoxifen Citrate)

Tamoxifen 20 mg is a non-steroidal medication classified as a SERM (Selective Estrogen Receptor Modulator). This means it has the unique ability to act as both an anti-estrogen and an estrogen, depending on the tissue it is in.

• For Breast Cancer (Primary Use): In breast tissue, Tamoxifen acts as a potent anti-estrogen. It is used to treat HR+ breast cancer in both pre- and postmenopausal women and is also used as a long-term therapy (for 5-10 years) to reduce the risk of cancer recurrence.
• For Male Use (Off-Label / PCT): In men, Tamoxifen is used to stimulate the body’s natural testosterone production. It is also used to prevent or treat gynecomastia (male breast tissue development).

How Does Tamoxifen 20 mg (Tamoxifen Citrate) Work?

Tamoxifen Citrate works by selectively binding to estrogen receptors.

• In Breast Tissue: It physically blocks estrogen from attaching to the receptors on cancer cells. Since these “HR+” cancer cells need estrogen to grow, Tamoxifen effectively “starves” them.
• In Men (PCT): It works by blocking estrogen receptors in the hypothalamus and pituitary gland. This action prevents estrogen’s negative feedback, which in turn “tricks” the brain into releasing more LH (Luteinizing Hormone) and FSH (Follicle-Stimulating Hormone). These hormones signal the testes to restart and increase natural testosterone production.
• In Other Tissues (e.g., Bone): In contrast, Tamoxifen acts as an estrogen in bone tissue, which can be beneficial in helping to maintain bone density in postmenopausal women.

Frequently Asked questions (FAQ) about Tamoxifen 20 mg

Is Tamoxifen the same as Nolvadex?

Yes, Nolvadex is the original brand name for Tamoxifen Citrate. Tamoxifen 20 mg (by Deva) and Nolvadex 20 mg are medically the same active ingredient and strength.

What is the difference between Tamoxifen (a SERM) and Arimidex (an AI)?

This is a critical distinction.

• Tamoxifen (SERM): Blocks estrogen from attaching to receptors (like a key breaking off in a lock). It does not lower the amount of estrogen in your body.
• Arimidex (Aromatase Inhibitor – AI): Stops the production of estrogen (it stops the aromatase enzyme). It actively lowers total estrogen levels.

Can Tamoxifen 20 mg be used to prevent gynecomastia?

Yes, this is a common off-label use. By blocking estrogen receptors in the breast tissue, it can prevent gynecomastia from developing or help treat it in its early stages.

What are the most common side effects of Tamoxifen?

The most common side effect is hot flashes. Other side effects can include mood swings, nausea, and fatigue.

Important Safety Information
