Tamoxifen 20 mg tablets

Reason for shortage

AstraZeneca global API shortage. Critical for breast cancer patients — oncologist guidance essential before any change.

What to do

1. 1.
   Contact your pharmacist — Your pharmacist can check current stock levels and advise on nearby pharmacies that may have supply. They can also assist with early dispensing to avoid running out.
2. 2.
   Ask your doctor about alternatives — Your GP or specialist can review whether a therapeutically equivalent alternative is appropriate for your situation. Never switch medicines without medical guidance.
3. 3.
   Request early repeat if eligible — If you have active repeats, your pharmacist may dispense an early repeat to build a short buffer supply while the shortage persists.
4. 4.
   Check TGA for updates — The TGA Medicine Shortage Information (MSI) database is updated regularly with expected resolution dates and approved substitutions.
5. 5.
   Consider compounding if appropriate — For some medicines (particularly oral liquids or specific doses), a compounding pharmacist may be able to prepare an equivalent formulation.
