Duphaston: Uses, Dosage, Side Effects, Fertility & Pregnancy Guide (2025)
Clear, up-to-date guide to Duphaston (dydrogesterone): what it’s for, how to take it, side effects, fertility and pregnancy use, and Australian availability.
If you’ve ever heard the name dydrogesterone and wondered what it does, you’re not alone. It’s a synthetic version of the natural hormone progesterone, and doctors use it for a handful of everyday health issues. Think of it as a backup plan when your body’s own progesterone isn’t doing its job.
Why does progesterone matter? It keeps the lining of the uterus ready for a fertilized egg, regulates the menstrual cycle, and supports early pregnancy. When levels dip, you might experience irregular periods, spotting, or trouble staying pregnant. That’s where dydrogesterone steps in, mimicking progesterone’s effects without many of the side‑effects of older hormone drugs.
1. Menstrual irregularities – If your cycle is too short, too long, or you get heavy bleeding, a short course of dydrogesterone can help reset things.
2. Threatened miscarriage – Some obstetricians give it in early pregnancy to support the uterine lining, especially if hormone tests show low progesterone.
3. Endometriosis pain – Hormone balance can ease the painful tissue growth that occurs outside the uterus.
4. Assisted reproductive technologies (ART) – In IVF cycles, dydrogesterone is often used after embryo transfer to keep the uterus receptive.
Most people tolerate dydrogesterone well, but it’s not a free‑for‑all. Common mild side effects include headache, nausea, and a feeling of bloating. If you notice severe stomach pain, unusual bleeding, or signs of a blood clot (like sudden leg swelling), get medical help right away.
Because it’s a hormone, it can interact with other meds like anticoagulants or certain antibiotics. Always tell your doctor about every prescription, supplement, or over‑the‑counter drug you’re taking.
When it comes to buying dydrogesterone online, a few rules keep you safe:
When you order, make sure the packaging shows the expiry date, batch number, and dosage strength (usually 10 mg tablets). Store the pills in a cool, dry place and don’t use them past the expiry date.
Bottom line: dydrogesterone can be a handy tool for hormone‑related issues, but it works best under a doctor’s guidance. If you think it might help you, schedule a chat with your GP, get a prescription, and then choose a licensed online pharmacy that follows the safety tips above.
