Nolvadex (Tamoxifen Citrate)

Tamoxifen citrate, the active ingredient in Nolvadex, is a selective estrogen receptor modulator presented as a oral tablet for oral use. It treats estrogen receptor‑positive breast cancer, helps prevent disease in high‑risk women, and is used to manage gynecomastia. GNH USA supplies Nolvadex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres, pharmacies and clinics worldwide.

Nolvadex (tamoxifen citrate) is employed in the management of estrogen‑driven conditions, primarily breast cancer and related disorders. - Estrogen receptor‑positive breast cancer (adjuvant): Reduces risk of recurrence after surgery or radiation. - Metastatic breast cancer: Delays disease progression and improves survival. - High‑risk women (chemoprevention): Lowers incidence of developing breast cancer. - Gynecomastia: Decreases breast tissue growth in males.

Tamoxifen citrate may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Hot flashes: Sudden feeling of warmth, often with sweating. - Nausea: Mild to moderate stomach upset. - Fatigue: Generalized tiredness. - Vaginal discharge or dryness: Changes in vaginal secretions.

Serious or Rare Side Effects: - Deep vein thrombosis or pulmonary embolism: Blood clots in veins or lungs. - Endometrial cancer: Abnormal growth of uterine lining. - Liver toxicity: Elevated liver enzymes or hepatitis. - Severe visual disturbances: Retinal changes affecting vision.

When prescribing Nolvadex, clinicians should consider several safety precautions to minimize risk. - Pregnancy: Contraindicated in pregnancy due to potential fetal harm; avoid use in pregnant women. - Thromboembolic risk: Assess history of clotting disorders before initiating therapy. - Liver function: Monitor hepatic enzymes regularly during treatment. - Ocular health: Perform baseline eye examination and monitor for visual changes. - Drug interactions: Review concomitant medications for CYP2D6 inhibitors or inducers. - Store at ambient temperature: Keep tablets below 25 °C in the original container, protected from moisture and light.

Tamoxifen citrate can interact with other medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid): - Strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine): Reduce conversion to active metabolites, decreasing efficacy. - Warfarin: May enhance anticoagulant effect, increasing bleeding risk. - Hormonal contraceptives: Potentially reduced contraceptive effectiveness.

Moderate Interactions (Monitor Closely): - SSRIs with moderate CYP2D6 inhibition (e.g., sertraline): May modestly affect tamoxifen metabolism. - Aromatase inhibitors: Combined use may increase hormonal side‑effects. - Antacids containing aluminum or magnesium: May affect absorption if taken simultaneously.
