Nolvadex (Tamoxifen Citrate)

Tamoxifen citrate, the active ingredient in Nolvadex, is a selective estrogen receptor modulator presented as an oral tablet for oral use. It is used to treat estrogen receptor‑positive breast cancer and to reduce the risk of recurrence in high‑risk patients. GNH USA supplies Nolvadex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres, pharmacies and clinics worldwide.

Nolvadex acts on estrogen‑dependent breast cancer pathways and is indicated for several clinical situations. - Estrogen receptor‑positive breast cancer (adjuvant): Reduces risk of disease recurrence after surgery. - Metastatic breast cancer: Improves progression‑free survival in advanced disease. - Prevention of breast cancer recurrence: Decreases likelihood of new tumor development following primary treatment. - High‑risk women for breast cancer: Lowers incidence of first‑time breast cancer in women with elevated risk.

Common Side Effects: - Hot flashes: Transient feeling of warmth and sweating. - Nausea: Mild to moderate stomach upset. - Menstrual irregularities: Changes in cycle length or flow. - Fatigue: Generalized tiredness. - Vaginal discharge: Increased lubrication or spotting. - Mood swings: Fluctuations in emotional state.

Serious or Rare Side Effects: - Thromboembolic events: Deep vein thrombosis or pulmonary embolism. - Endometrial cancer: Unusual uterine bleeding or pain. - Liver toxicity: Jaundice or elevated liver enzymes. - Severe allergic reaction: Rash, swelling, or difficulty breathing. - Visual disturbances: Blurred vision or retinal changes. - Pulmonary embolism: Sudden shortness of breath or chest pain.

Before initiating Nolvadex, consider the following precautions. - Pregnancy: Contraindicated (Category D) due to potential fetal harm. - Thromboembolic risk: Monitor for signs of deep vein thrombosis or pulmonary embolism. - Liver function: Assess hepatic enzymes prior to therapy and periodically thereafter. - Vision changes: Promptly report any ocular symptoms such as blurred vision. - Drug interactions: Review concomitant medications for CYP2D6 inhibitors and anticoagulants. - Store at ambient temperature: Keep below 25 °C in the original container, protect from moisture.

Nolvadex may interact with several drug classes; monitoring is essential. Major Interactions (Avoid): - Strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine): May increase tamoxifen plasma levels. - Warfarin: Potential enhancement of anticoagulant effect, increasing bleeding risk. - Aromatase inhibitors: May counteract estrogen‑modulating actions. Moderate Interactions (Monitor Closely): - SSRIs: May reduce effectiveness of hot‑flash management. - Antacids: May affect oral absorption if taken simultaneously.
