About Duphaston
Duphaston (10 mg oral tablet) is a prescription-only medication used in hormone therapy for women. It contains the synthetic progestogen dydrogesterone, which mimics the activity of natural progesterone to support the menstrual cycle, assist conception, and treat a range of estrogen-dominant conditions. In Australia the product is approved by the Therapeutic Goods Administration for luteal-phase support in assisted reproduction, management of menstrual disorders, endometriosis, and secondary amenorrhoea. Off-label use may be considered for threatened miscarriage or pre-term labour under specialist supervision.
What is Generic Duphaston (Dydrogesterone)?
Generic Duphaston (Dydrogesterone) belongs to the class of synthetic progestogens, a subgroup of hormonal agents that act on progesterone receptors. The medication received TGA approval in the early 2000s and is supplied as a 10 mg film-coated tablet for oral administration. It is marketed in Australia as a prescription product and is not listed on the Pharmaceutical Benefits Scheme, meaning patients typically obtain it through private prescription.
How Duphaston Works
Dydrogesterone binds selectively to the progesterone receptor isoforms PR-A and PR-B, reproducing the downstream effects of endogenous progesterone without significant androgenic or estrogenic activity. By activating these receptors, the drug stabilises the endometrial lining, suppresses the proliferative actions of estrogen, and promotes secretory transformation essential for implantation.
Pharmacokinetic data show rapid oral absorption, with peak plasma concentrations reached within 1-2 hours. The drug’s half-life ranges from 5 to 7 hours, allowing once-daily dosing for most indications. Metabolism occurs primarily via hepatic CYP3A4 pathways, and metabolites are excreted renally. The relatively short half-life explains why steady-state levels are achieved within a few days of therapy, providing prompt hormonal support when needed.
Why Duphaston Is Used for Hormone Therapy and Women’s Health Conditions
- Luteal-phase support in assisted reproduction - By recreating a progesterone-rich environment, Duphaston enhances endometrial receptivity, increasing implantation rates in IVF cycles. Guidelines from the Royal Australian and New Zealand College of Obstetricians and Gynaecologists place progestogen support as a first-line adjunct after embryo transfer.
- Management of menstrual disorders (e.g., irregular cycles, heavy bleeding) - The drug counteracts unopposed estrogen, reducing endometrial over-growth and stabilising bleeding patterns. Clinical trials report a 60 % improvement in cycle regularity compared with placebo.
- Endometriosis - Progesterone resistance is a hallmark of endometriosis; dydrogesterone’s selective receptor activity alleviates pain and suppresses ectopic endometrial tissue, offering symptom relief comparable to other progestins but with fewer androgenic side effects.
- Secondary amenorrhoea - In women with hypothalamic or pituitary dysfunction, Duphaston provides the missing progesterone signal, prompting withdrawal bleeding and restoring normal hormonal feedback loops.
- Threatened miscarriage (off-label) - Small RCTs suggest that early luteal support may reduce miscarriage risk, though the indication remains unapproved in Australia.
Compared with natural micronised progesterone, dydrogesterone has a more predictable oral bioavailability and fewer gastrointestinal complaints, making it a convenient alternative for many patients.
Off-Label and Investigational Uses of Duphaston
Evidence from limited randomised studies indicates potential benefit in preventing pre-term birth when administered to women with a short cervix, and in treating chronic pelvic pain associated with adenomyosis. Neither indication is approved by the TGA, and clinicians should only consider such use under the direct supervision of a qualified specialist. Off-label use should be evaluated on a case-by-case basis, weighing the existing data against individual risk factors.
Is Duphaston Right for You?
Ideal candidates include women undergoing IVF, those with documented luteal-phase deficiency, and patients experiencing irregular or heavy menstrual bleeding unresponsive to first-line hormonal contraceptives. The medication is generally well tolerated in the adult female population; however, caution is advised in women with severe hepatic impairment, known hypersensitivity to dydrogesterone, or a history of thromboembolic disease. Pregnancy and lactation considerations are addressed in the product information, and the drug is not recommended for use in children or men.
Taking Duphaston Effectively
- Timing: Take the tablet once daily, preferably at the same time each morning to maintain steady plasma levels.
- Food interactions: Dydrogesterone can be taken with or without food; a light meal may reduce occasional stomach upset.
- Missed dose: If a dose is forgotten within 12 hours, take it as soon as remembered; otherwise, skip the missed tablet and continue the regular schedule-do not double-dose.
- Travel: For long trips across time zones, keep dosing time consistent with your home schedule; a short adjustment (±2 hours) is acceptable.
- Alcohol: Moderate consumption does not significantly affect drug levels, but excessive intake may increase the risk of hepatic strain.
Understanding Side Effects and How to Manage Them
Common adverse events-mild nausea, breast tenderness, and headache-stem from the progestogenic activity on central nervous system receptors and peripheral tissues. Taking the tablet with food or a small snack often eases gastrointestinal discomfort. Headaches can be mitigated by maintaining adequate hydration and regular sleep patterns.
Less frequent but serious reactions, such as signs of hepatic dysfunction (jaundice, dark urine) or venous thromboembolism (leg swelling, sudden chest pain), reflect rare off-target effects and require immediate medical attention. Patients should be educated to report any unusual symptoms promptly.

Frequently Asked Questions
-
Can I use Duphaston to delay my period? Dydrogesterone can postpone withdrawal bleeding when taken throughout the luteal phase, but this use is off-label and should be discussed with a gynaecologist.
-
Is it safe to take Duphaston while on hormonal contraception? Concurrent use is generally unnecessary and may increase the risk of hormonal excess; clinicians usually advise stopping one agent before starting the other.
-
How long does it take to see improvement in heavy menstrual bleeding? Most women notice a reduction in flow within one to two cycles, although full stabilisation may require three months of continuous therapy.
-
Will Duphaston affect my fertility after stopping it? The drug does not impair ovarian reserve; normal cycles typically resume within a few weeks after discontinuation.
-
Are there any dietary restrictions while on Duphaston? No specific foods need to be avoided, but a balanced diet supports overall hormonal health.
-
Can I purchase Duphaston without a prescription through your platform? Australian law requires a valid prescription for all progestogens, and our service only processes orders that include a prescriber’s authorization.
-
What should I do if I experience severe breast pain? Persistent or worsening breast discomfort warrants medical evaluation to rule out underlying pathology.
-
Is Duphaston compatible with herbal supplements like chasteberry? Some botanicals possess mild progestogenic activity; combining them may amplify effects, so discuss any supplement use with your healthcare provider.
-
How does Duphaston compare with micronised progesterone capsules? Dydrogesterone offers more consistent oral absorption and fewer gastrointestinal side effects, whereas micronised progesterone may be preferred for patients seeking a natural hormone source.
-
Will taking Duphaston increase my risk of blood clots? The progestogenic component carries a low but present risk of venous thromboembolism, especially in women with pre-existing risk factors; risk assessment is essential before initiation.
