2. INR 4.5–10 (No bleed): Routine use of Vitamin K is NOT recommended.
3. INR > 10 (No bleed): Give Oral Vitamin K (2.5–5 mg).
4. Major Bleeding (Any INR): Give IV Vitamin K (5–10 mg) and 4-factor Prothrombin Complex Concentrate (PCC).

Flashcard 138: When is Tamoxifen used in Breast Cancer management?
Answer: • ER/PR +ve premenopausal women (First-line)
• ER/PR +ve postmenopausal women (Alternative to Aromatase Inhibitors)
• Chemoprevention in high-risk women
• Male breast cancer (DOC)
Extra: Tamoxifen is a Selective Estrogen Receptor Modulator (SERM). While primarily the drug of choice for hormone receptor-positive premenopausal women, it can be used in postmenopausal women if Aromatase Inhibitors (AIs) are contraindicated or not tolerated. It also significantly reduces the risk of recurrence and is used for primary prevention in high-risk individuals. Unlike AIs, Tamoxifen is also the standard for treating male breast cancer.
